PRODUCT INSPECTION AND TEST

The Products of Dean Pump Division are subject to thorough and rig-

orous quality control and inspection procedures through out the

whole of the manufacturing process to assure proper operation in full

conformity with established performance stand ards. On completion

of inspection each unit is oiled sealed against the entrance of dirt

and tagged with a signed certificate of inspection prior to shipment.

Each pump when shipped is ready to perform the service for which

it was designed with minimum maintenance and expense if properly

installed and operated in accordance with the instructions furnished.

WARNING

Read the instruction manual completely before installing filling oper-

ating or maintaining this equipment.

Obtain read and heed the MSDS (Material Safety Data Sheet) for

the fluids being handled before attempting to fill operate or main-

tain this equipment. Obtain instructions from the Safety Engineer

responsible for your facility before performing any work on the

pumping equipment and systems.

Proper storage while not in use and proper installation and startup

are essential for successful pump operation. Misuse or improper stor-

age installation or operation of pumps may result in serious loss or

damage. Dean Pump Division is not responsi ble for any loss or dam-

age resulting from causes beyond its control and is not liable for

charges for work performed or materials furnished to repair such

loss or damage.

All installation, operation, and maintenance must be done by thor-

ou hly qualified personnel in strict accordance with this manual and

must comply with all local, state and Federal codes. Only Dean

authorized service parts must be used in the repair of these pumps.

RECEIVING PUMP

When the pump is received from the transportation company it

should be promptly inspected for dama e and such dama e noted

on the bill of ladin before it is si ned. Claims for shippin dama e

must be filed a ainst the carrier.

Care should be exercised in unloadin and handlin the pump.

STORAGE

Pumps must be properly covered and protected against mois ture

dirt and physical damage during storage prior to installa tion. If pro-

longed storage is anticipated a heavy protective coating should be

applied to bearings and all exposed machined surfaces. A rust pre-

ventative must be used to protect all steel or cast iron parts.

Compression packing or mechanical seals should be removed and

stored as well as protected separately.

Pumps must also be protected from moisture dirt and physical dam-

age during and after installation while the system is being complet-

ed. Pumps “stored” on their foundations must be com pletely checked

for proper installation prior to start-up.

Care in storage and installation will preserve the built in quality of

each Dean Product.

INSTALLATION

Always wear the appropriate protective apparel when working on

or around the pumping equipment. Safety glasses with side shields

heavy work gloves (use insulated work gloves when handling hot

items) steel-toed shoes hard hat and any other protective gear as

needed for protection. One example of other gear would be breath-

ing apparatus when working near toxic materials. Use lifting

devices manufactured expressly for the purpose of lifting to move

the pumping machinery. Do not attempt to lift the assembly or its

components manually. Use only devices with lifting capabilities in

excess of the weight of the unit being lifted. Inspect straps chains

hooks etc. for damage and lifting capability before use. Lift only at

the center of gravity.

Personal injury death and/or equipment damage could occur if

good lifting practices are not used.

APPLICATION AND REAPPLICATION

At the time of installation the equipment received should have

already been selected for the service required. You must read the

paperwork for the installation and check the serial number of the

pump to assure that you are installing the correct pump into the ser-

vice for which it was selected.

Many pumps look identical from the outside but can be made of dif-

ferent materials and/or be constructed differently inside. Personal

injury death equipment damage product (pumpage) damage

and/or product loss could occur if the incorrect pump is installed.

Do not transfer an existing pump to any other service conditions until

you have thoroughly reviewed the pump construction materials siz-

ing sealing pressure containing capability head/capacity capabili-

ty and temperature capability with respect to the required service.

Consult your Dean Pump sales engineer with all the service require-

ments and a full description of the existing pump (including the serial

number) seal and sub-systems so that we can assist you in a suc-

cessful reapplication.

PUMP FOUNDATION

The pump foundation provides rigid support to the baseplate and

maintains the alignment of the pumping unit. Baseplates are

designed to rigidly support the pump and driver without vibration or

distortion only when they are properly set leveled and secured to

the foundation.

The purchaser may elect to mount the pump without grouting the

baseplate. In any case the baseplate must be fully supported by the

customer’s mounting means to prevent vibration and distortion.

BASEPLATE MOUNTING AND ALIGNMENT

The sequence of mounting which must be observed for proper base-

plate and pump mounting is:

1) Place baseplate with pump and driver mounted thereon on the

pump foundation.

2) Use wedges under the baseplate edges at each foundation

bolt to properly support and level the unit. Check this with a

spirit level. Pull down the baseplate mounting bolt nuts tightly

and recheck for level. Correct if necessary.

3) Align the driver to the pump. See “Pump and Driver

Ali nment’’ on page 4.

4) Grout the baseplate. Do not rout the baseplate to the founda-

tion until the pump and driver are correctly ali ned. The

baseplates are provided with grouting holes. Fill the entire

void under the baseplate with grout and firmly embed the

baseplate edges.

5) Connect the suction and discharge piping without forcing the

piping into position. See “Suction and Dischar e Pipin ’’ on

page 4. The pipe flanges must line up with the pump flanges

“ freely”.

Install a “new”bolt of the correct size per ASME/ANSI

B16.5 and the correct material per ASME/ANSI B16.5 in

every bolt hole. Tighten all bolts evenly. Use only new

uncorroded fasteners.

WARNING:

Strain caused by “forcin ”, improper flan e boltin , and/or

misali nment may cause failure of the pumpin unit, flan es, pipin

and/or fluid (pumpa e) release which could cause personal injury,

death, and/or dama e to this and/or other equipment.

6) Recheck pump and driver alignment to ensure that no distortion

of the pump unit has been caused by piping strain. Correct

piping if misalignment has occurred and again align pump and

driver.

7) Connect all other (auxiliary) piping necessary for safe and

successful operation of the equipment in the specific service

conditions of the application. See “Pump Coolin

Requirements” on page 6.

WARNING:

Make sure that all pipin is installed into its correct connection.

Installation of a pipe into an incorrect location could result in an

explosion and personal injury or death as well as dama e to this

and/or other equipment. Install pressure relief valves in any cavities

that could be subjected to pressures in excess of the allowable work-

in pressure. Explosion, personal injury, death, and/or dama e to

this and/or other equipment may occur if pressure exceeds allow-

able.

One example of the above would be the coolin jacket around the

seal chamber. If this chamber were full of water and someone

would close both the inlet and outlet valves and then operate the

pump at 500 de rees fahrenheit, the vapor pressure of the water,

665 PSIG, would far exceed the capacity of the jacket and possibly

other parts. In this example, a relief valve must be installed between

the pump and the outlet valve.

8) Recheck the alignment between the driver (motor

turbine or engine) and pump shafts. Installation of piping

TYPICAL FOUNDATION LAYOUT

may have forced the pump out of alignment. If so correct the

piping to remove the distorting load and realign the pump

and driver.

9) The pump and driver alignment must again be checked at the

operating temperature and alignment corrected under the hot

condition.

10) After about two weeks of normal pump operation the pump

and driver alignment should again be checked under the hot

condition. If alignment is still correct the driver feet may be

doweled to the baseplate. If the alignment has changed

realign the unit and recheck after two weeks.

SUCTION AND DISCHARGE PIPING

Suction and discharge nozzle sizes of Dean pumps are selected for

proper performance of the pumping unit and are not intended to

determine the suction and discharge pipe sizes. Pipe sizes must be

determined by the user based on the system requirements.

Suction piping should have a minimum friction loss and thus should

be as short and straight as possible with a pipe diameter as large as

economically feasible for the flow rate handled. Suction piping

should never be smaller in diameter than the suction nozzle size.

When the suction piping is larger than the suction nozzle size an

eccentric reducer is required at the suction flange and must be

installed with the taper located on the underside to eliminate air or

vapor pockets. The section of piping attached to the suction flange

of the pump should be straight for a length of eight pipe diameters

or more.

Discharge piping may be the same size as larger or smaller than

the discharge nozzle as the system flow may demand.

In new installations or rebuilt systems dirt pipe scale welding slag

and general construction debris may get into the piping. It is impor-

tant to prevent this material from entering the pump and damaging

pump parts mechanical seal faces or seal chamber packing.

Mechanical seal parts are especially subject to damage even by

very small particles. To prevent damage a strainer or filter installed

in the suction line is recommended. Commercially available strainers

or filters as recommended by their manufacturers can do an excel-

lent job. In addition special filtering and mechanical seal flushing

may be required. Consult your Dean representative. Suction line

screens or strainers may usually be removed when after several

days of use no dirt has been collected and the system is clean.

of the pump shaft when the unit is running. Although pumps and

drivers are check aligned at the factory this is only to confirm that

the unit can be aligned in the field and handling during shipment

and installation will cause the alignment to change. The pump and

driver ali nment must always be checked and corrected before the

baseplate is routed to the foundation and a ain before the pump

is first started. If the baseplate mounting instructions have been

carefully fol lowed no difficulties in making the alignment should

be experi enced. Failure to properly ali n the unit will result in

vibra tion, short bearin life, and reduced mechanical seal or shaft

packing life.

Pumps are not constructed to be used as pipe anchors. Both suc-

tion and discharge piping must be supported independently of the

pumping unit and thermal expansion joints provided to guard

against expansion loads on the pump. Pipes should be anchored

between the expansion joint and the pump and as closely to the

pump as possible. Failure to provide proper piping support and

expansion joints may impose strains on the pump ing unit which

will result in serious misalignment. Maximum allowable piping

loads are shown on page 5 in this manual.

No allowance for thermal expansion is made for motor driven

units in mounting the driver. Allowance for turbine mounting

should be in accordance with the turbine manufacturer’s recom-

mendations. Final ali nment must always be checked and correct-

ed at the operatin temperatures of the pump and driver.

Misalignment of the two shafts is of two kinds. The first of these is

angular misalignment where the axis of one shaft is at an angle

from the other. The other is offset alignment where the center of

one shaft is offset from the center of the other shaft. These effects

usually occur together so that both angular and offset misalignment

are present.

Coincident alignment of the driver and pump shaft is measured at

the faces of the coupling hubs. Because of the variety of coupling

types furnished at customer’s request the procedure here given is

general in nature but may be applied by simple adaption to most

coupling types.

The first step is to remove the spacer from the coupling. To one of

the remaining coupling hubs firmly seated on the shaft attach a

dial indicator. Let the indicator button ride on the face of the other

coupling hub and near the outside diameter. See illustration on

page 5. Rotate the shaft on which the dial indicator is mounted

allowing the indicator button to move on the stationary coupling

hub. The indicator dial movement will show the difference in dis-

tance between the two hubs. This indicates the amount of angular

misalignment between the hubs and therefore the shaft axes.

Good practice suggests alignment to within 0.002" T.l.R.

TYPICAL PUMP PIPING

Remember that screens and filters in the suction line are restrictive

devices which reduce the net positive suction head (NPSH) available

to the pump and should be considered at the time the system is

designed.

PUMP AND DRIVER ALIGNMENT

Proper running life of a pump and driver unit depends on the accu-

racy with which the axis of the driver shaft coincides with the axis

MAXIMUM MOMENTS APPLIED TO A PUMP ON A FULLY BOLTED

AND GROUTED BASEPLATE. LOADS ARE TO BE APPLIED ONLY

THROUGH THE SUCTION AND DISCHARGE FLANGES.

Maximum allowable forces and moments calculated from these force equations or the tabulated moment tables are

those resulting in a maximum of .010 inch movement of the shaft measured at the shaft coupling when the pump is

mounted on its baseplate and that baseplate is fully bolted to a properly designed foundation and is fully grouted

in place. For a full discussion see API Standard 610 5th Edition.

Data Sheet 1198

To check the offset alignment mount the dial indicator as above

except with the indicator button on an outside diameter of the sta-

tionary coupling hub. See illustration below. Rotate the shaft on

which the dial indicator is mounted allowing the indicator button to

ride on the outside diameter of the stationary hub. The indicator dial

move ment will show the difference in the center locations of the two

shafts. Good practice suggests alignment to within 0.002" T.I.R.

Angular and offset alignment is adjusted by placing thin metal shims

under the driver mounting feet to bring the drive into exact alignment

with the bolted down pump. If misali nment is of major proportions,

the baseplate has been improperly installed on the foundation and

must be releveled before proceedin with ali nment.

On the R440 series pumps moderate alignment adjustments may

be made by using the jack bolts provided on the bearing housing

foot. Loosen the two bearing housing foot hold-down bolts and the

jack bolt lock nuts. Adjustments of the jack bolts may then be made.

After each change by shims or jack bolts it is necessary to recheck

both angular and offset alignment of the coupling. After the pump

and driver are aligned tighten all hold-down and jack bolt lock nuts

and then recheck alignment.

Allowable error of shaft alignment is somewhat dependent on the

coupling type. However, the closer the runnin ali nment, the better

the runnin life will be.

PUMP COOLING REQUIREMENTS

Pumps may be furnished with the following jackets or cooling coil:

1) Stuffing box

2) Mechanical seal gland (optional)

3) Casing pedestals (optional)

4) Bearing housing cooling coil (optional)

Cooling is recommended under the following conditions:

STUFFING BOX COOLING

1) With a mechanical seal when the application requires

cooling.

2) With a mechanical seal when pumping liquids of 0.75 specific

gravity or less when the pumping temperature permits further

cooling.

3) With stuffing box packing except Grafoil at temperatures

above 250°F.

MECHANICAL SEAL GLAND COOLING

When the mechanical seal application requires cooling of the

seal faces. This depends on the liquid pumped and the pumping

temperature.

BEARING HOUSING COOLING

At pumping temperatures below 500°F such cooling is rarely

necessary. Excessive cooling of the bearing housing may lead

to early bearing failure from moisture condensation and contami-

nation of the oil.

COOLING WATER PIPING

The cooling water piping depends on what cooling coil or jackets

are furnished and used. Jackets to be piped in series are Casing

Pedestal Cooling Stuffing Box Cooling and Bearing Housing

Cooling with the cooling water to flow in that sequence. Not all of

these jackets will necessarily be used. All other jackets or cooling

coil should be piped in parallel with separate flow to each. The cus-

tomer must provide piping and a shut-off valve on each cooling inlet.

The customer must also provide the outlet piping from each jacket or

cooling coil fitted with a pressure relief valve set at a maximum of

150 PSIG and then a flow control valve. Pipe each outlet from the

valve to it's own sight drain or through a suitable flow indicating

device into the plant cooling water system.

In no case should the outlets be piped into the municipal water

system.

COOLING WATER FLOW RATES

Stuffin box coolin , when used has flow rates related to pumping

temperature. See the chart below. The lower flow rates will lead to

higher cooling water temperature and promote more rapid scaling

within the jacket. Higher flow rates will do no harm.

Mechanical seal land coolin flow should be adjusted to about 1/2

GPM.

Bearin housin coolin flow rate when not in series with the stuff-

ing box cooling should be adjusted to 1/2 GPM. This will maintain

the oil temperature below 130°F at all pumping temperatures.

The pumps may be operated without bearing housing cooling if

experience with the particular installation shows that the bearing

temperature without cooling does not rise above 200°F.

As stated before pumps operating at 500°F and lower seldom

require bearing housing cooling.

Casin pedestal coolin flow rates are equal to stuffing box cooling

flow rates when piped in series. If piped separately the flow need

not be over 1/2 GPM.

WARNING—EXTREME HAZARD TO PERSONNEL: When cool in

water is used to cool the stuffin box, land, or bearin housin

jackets, it is mandatory that the coolin water be allowed to flow at

any time the pump is runnin . Closin the inlet and/or outlet valves

under runnin conditions may result In the water In the jackets

reachin hi h pressure which may lead to the rupture of a water

jacket with extreme hazard to personnel.

WARNING—EXTREME HAZARD TO PERSONNEL: Improper connec-

tion of coolin water pipin may result in the injection of coolin

water into the pump stuffin box and into the pumpa e. Dependin

on temperature this may cause a violent steam explosion in the

pump, pipin , or associated equipment with extreme hazard to per-

sonnel. It may also cause serious contamination of the pumpa e and

heavy corrosion of pump or equipment parts.

CASING PEDESTAL COOLING

Casing pedestal cooling is used to equalize and minimize thermal

expansion of the pedestal pump supports.

CONNECTION

PIPING CONNECTIONS FOR R5000 SERIES PUMPS

Connections (1) and (3) are cooling water inlets. Connections (2)

and (4) are cooling water outlets. Do not control cooling water flow

with a valve on connections (1) and/or (3). Connections (3) and (4)

may be reversed if so desired.

Openings (1) and (2) are stuffing box cooling jacket connections

and are covered at the manufacturing plant with thread protectors

for shipment.

Openings (3) and (4) are bearing housing oil cooler connections

and are covered at the manufacturing plant with thread protectors

for shipment.

Openings (5) and (6) are connections into the center of the mechani-

cal seal cavity (or to the lantern ring if the box is packed) and are

sealed with standard metal threaded pipe plugs at the manufactur-

ing plant.

Connection (7) is for the “Automatic Oiler/Bull’s Eye Oil Level

Indicator” which is shipped in a box in the coupling guard assembly

and must be installed into one of these (two) connections. There is a

connection (7) on both sides of the pump. One of these connections

is plugged and the other has a plastic shipping protector installed.

Remove the plastic shipping protector and install the Automatic

Oiler. The Automatic Oiler can be moved if so desired to opposite

side of the pump. See Pump Lubrication on page 8.

Connection (8) is the oil drain. This is plugged with a standard

metal threaded pipe plug.

Connection (9) is the oil reservoir vent which is shipped installed.

Opening (10) is the oil fill connection. This connection is plugged

with a standard metal threaded pipe plug. There is a connection

(10) on both sides of the pump so that the oil reservoir may be con-

veniently filled from either side.

Lubrication of the ball type bearings in Dean pumps is by oil

contained in the sump of the bearing housing (26). The oil must

be a good grade of rust and oxidation inhibited non-foaming

industrial oil with a viscosity of approximately 500 SSU at

100°F. This will be an ISO 100 oil.

Failure to level the pump assembly when the entire unit is

installed may adversely affect the oil level and reduce bearing

life. Proper care should be taken to avoid this condition.

The R5000 series pumps are supplied with an “Automatic Oiler”

that has a built-in Bull’s Eye Level Indicator. The Automatic Oiler was

shipped in the cloth accessories bag attached to the pump to avoid

damage. Screw the glass reservoir from the body of the oiler. Install

the oiler body into either of the upper 1” NPT tapped holes (connec-

tion #7 on page 7) on either side of the bearing housing (26). The

bearing housing is supplied with duplicate connections on both sides

so that you can place the oiler on the side that is most easily viewed.

The pump was shipped with a plastic shipping protector in one of

the connections and the other is plugged.

Fill the sump of the bearing housing (26) through one of the (two)

NPT tapped openings (connections #10 on page 7) on the side

until the level reaches the center of the Bull’s Eye level indicator. The

Automatic Oiler will maintain this level as long as there is any oil in

the glass reservoir of the automatic oiler.

Invert the glass reservoir so that the bias cut tube is pointing

upward and fill it with oil through this tube. Screw the glass

reservoir back into the body of the Automatic Oiler.

The oil should be drained and replaced at regular intervals the

intervals depending on the atmospheric conditions (dust soot

corrosive vapors humidity temperature variations etc.) prevailing at

the pump installation site. The bearing housing should be flushed

with a good solvent before the oil is replaced.

Pumps ar shipp d from th factory without oil in th b aring housing.

PUMP LUBRICATION

TYPICAL PUMP PIPING

It is important that a pump should never be subjected to thermal or

pressure shock. The liquid should therefore be allowed to flow into

the casing slowly. A centrifugal pump should never be started until

all the parts are up to the temperature of the liquid to be pumped.

If the pump is equipped with cooling water piping this should be

turned on before filling the pump.

FILLING

WARNING:

Before fillin the pump with liquid, check to see that all possible leak

locations are sealed. See that the point where the pump shaft enters

the pressure containin cavity is sealed. Normally this sealin is

accomplished with shaft packin or a mechanical face seal. See that

all of the connections into the pressure containin cavity are sealed

or connected to a related pipin system that also has all possible

leak paths sealed. Do not plu unused jacket cavities, as this could

develop dan erous pressure build-up. Use a wrench on all bolted

joints to apply torque to assure that all askets are sealed in a ti ht

joint. Check to see that all threaded pipe connections are also ti ht

enou h to seal the Liquid pressure that will be applied when the sys-

tem is started.

When the source of liquid supplied to the pump is below atmos-

pheric pressure or located below the pump the pump must be

primed prior to start up. The priming may be ac complished in any

of several ways three of which are listed.

1) An exhauster may be connected to the discharge piping

between the pump and the discharge shut-off valve. With the

discharge shut-off valve closed and the suction valve open the

air can be exhausted from the pump and piping.

2) With a foot valve installed in the suction piping the pump may

be filled with liquid introduced somewhere above the pump in

the discharge line. The seal chamber should be vented to

allow complete filling. A foot valve may create extensive losses

and should be taken into consideration in calculating the avail-

able NPSH.

3) A vacuum pump (preferably a wet vacuum pump) may be

used for evacuating air from the pump and piping. The

vacuum pump should be connected as is the exhauster

covered in No. 1.

When the source of liquid supplied to the pump is above atmospher-

ic pressure or above the pump centerline the pump may be filled by

venting through a bleed off line to atmosphere or back to the pump

suction source.

It Is most Important to check the direction of rotation of the pump

before allowin the pump to come up to speed. The pump was

shipped with the coupling spacer not installed to allow alignment

and motor rotation direction check. If however someone installed

this spacer assembly lock-out the power to the driver (motor turbine

engine etc.) and remove the spacer assembly at this time. To check

rotation direction push the starting button and instantly push the stop

button. This will allow the motor to turn over a few revolutions and

the direction of rotation to be observed. A direction of rotation arrow

is shown on the front of the pump casing. If rotation is incorrect

change the wiring connections and recheck rotation. Operatin the

pump in reverse rotation may cause extensive dama e.

WARNING:

Lock-out the power to the driver (motor, turbine, en ine, etc.)

Install the shaft couplin spacer assembly. Be sure that you install all

the retainin devices and bolts and that they are ti ht. Read and

comply with the couplin manufacturers instructions. Personal injury,

death, and/or equipment dama e could occur if the couplin spacer

is not properly installed. Remove all debris and tools from the area

near the shafts and the shaft couplin . Do this to assure that nothin

is cau ht and thrown by the rotatin parts when the pump is start-

ed. Bolt the couplin uard securely into place, checkin to assure

that it is not contactin any parts that will rotate when the pump is

started.

OPERATING

WARNING:

Before startin the unit, see that all personnel are a safe distance

away from all possible hazards, that all sub-systems are connected

and operatin , that all debris has been removed, that the shaft cou-

plin uard is securely in place, and that the pump is full of liquid.

Do not operate this pump at shut-off (no flow) as an explosion may

result. This can occur with any liquid, even “cold water”. Personal

injury, death, equipment dama e, and/or loss of product

(pumpa e) is likely to occur. If your system is operated where it is

possible for all outlets of the dischar e from the pump to be closed

while the pump is still operatin , a modification of the system needs

to be made to assure a continual flow of pumpa e throu h the

pump. NOTE: Some people have a belief that a bypass line from the

dischar e side of the pump to the suction side of the pump will

relieve this problem, this is “NOT TRUE”; DO NOT ATTEMPT THIS.

WARNING:

Do not operate a pump at a low flow condition, unless provision has

been made to prevent dan erous heat build up within the pump

casin . The liquid in the pump will heat up and this may result in

hi h pressure in the pump in a short time. Such pressure may result

in a rupture of the pressure-containin parts and cause severe haz-

ard to personnel and/or dama e to the system.

A centrifu al pump should never be run without liquid In the casin .

Extensive dama e may result, particularly to the mechanical seal or

compression packin . When the pump is equipped with a mechani-

cal seal, vent the pump seal chamber throu h the seal connection to

provide lubrica tion to the mechanical seal faces.

A centrifugal pump should be started with the suction valve open

and the discharge valve opened a slight amount.

As soon as the pump is up to speed the discharge valve must be

opened slowly. A centrifugal pump cannot be operated with the

discharge valve closed without heating up dangerously. During the

first several minutes of operating watch the pump carefully for

overheating vibration and other abnormal conditions. If trouble

develops stop pump at once and correct the problem.

STARTING THE PUMP

PUMP START UP CHECK LIST

To avoid prolonged down time and facilitate rapid repair of dam-

aged pump parts Dean recommends that the pump user maintain a

minimum stock of spare parts. If the pump service is critical or the

pump parts are of special materials spare parts stock is even more

important to the user. Such spares inventory may extend from a

spare mechanical seal or seal parts through complete casing back-

cover-impeller-bear ing housing assemblies prepared for immediate

insertion in the pump casing. Consult your Dean representative who

will assist you in selecting your spares stock.

ORDERING SPARE PARTS

Spare part orders will be handled with a minimum delay if

the following information is furnished by the customer with the

order:

1) Give the pump serial number and size. These may be

found on the pump name plate. The serial number is also

stamped on the suction flange or the top edge of the bear-

ing housing front flange.

2) Give the part name part number and material of part.

These should agree with the standard parts list.

3) Give the quantity of each part required.

4) Give complete shipping instructions.

SPARE PARTS

These points must be checked after pump installation and before

startin up the pump.

1) Read instruction manual thoroughly and understand it.

2) Review pump order head sheet for the service rating of the

pump and any special features.

3) Check all piping connections making certain that they are both

tight and in the proper places. All piping includes seal cooling

or heating piping.

4) Make sure that the baseplate has been properly installed.

5) Check the electrical or steam line connections to the driver.

6) Break the coupling by removing the coupling spacer assembly

and bump the motor starting button to check motor rotation.

Operating the pump in reverse rotation may cause extensive

damage. If driver rotation is correct replace the coupling spac-

er. If not connect the wiring for proper rotation and recheck.

7) Check coupling for proper alignment. Realign if neces sary.

8) If pump seal chamber is packed check to be sure that

gland stud nuts are pulled up only finger tight and that the

gland is not cocked.

9) Rotate the pump shaft by hand to be sure there is no

binding or rubbing within the pump or driver. Correct any

difficulties at once.

10) Check to see that the pump is properly lubricated.

11) Remove all dirt waste tools and construction debris from

the area.

12) Check to see that the coupling guard is securely in place.

WARNING:

Work must be performed only by thorou hly trained and qualified

personnel to assure quality repair and to reduce the possibilities of

injury to personnel and/or dama e to equipment. If you do not

have personnel who are capable of safe quality repair of this equip-

ment, we advise you to return the equipment to DEAN PUMP to be

repaired.

When it is necessary to open the pump and/or the pumpin system

the fluid will be exposed to the atmosphere and personnel in the

area. For the safety of all involved, the risk of exposure of personnel

to the hazards of the pumpa e can be reduced by flushin the entire

system with a compatible, nontoxic, non-hazardous, stable Liquid

before openin the pump or the system. In all cases, where the sys-

tem is flushed or not, use the utmost care around the pumpa e and

the, pumpin system.

Always wear the appropriate protective apparel when workin on

or around the pumpin equipment. Safety lasses with side shields,

heavy work loves (use insulated work loves when handlin hot

items), steel-toed shoes, hard hat, and any other protective ear as

needed for protection. One example of other ear would be breath-

in apparatus when workin near toxic materials.

Use only top quality tools.

a) Stop the pump. Turn off the power supply (electricity steam

etc.) to the pump driver (motor turbine engine etc.) and lock

the switching device so that it can not be restarted. Tag the

switching device so that no one will attempt to restart the unit.

b) Close the suction and discharge valves completely to isolate the

pump from the system. Lock the valves in the closed position

and tag them so that no one will attempt to open them.

c) Turn off lock out and tag all sub-systems and auxiliary equip-

ment and auxiliary supply lines to isolate the pumping unit from

any and all power energy and/or fluids.

WARNING:

Do not attempt to perform any work on the unit until you are confi-

dent that the pump and its contents have been stabilized at ambient

temperature, and atmospheric pressure.

Put on protective wear to protect human tissue from attack by the

fluids contained in the pump and any sub-systems, and from any

vapors or fumes that could possibly be released from these fluids.

This could mean breathin apparatus face shields, heavy lon sleeve

rubber loves, rubber apron, hood, and possibly more, dependent,

of course, on the properties of the fluids involved and the installed

drain and vent pipin arran ement. Personal injury and/or death

can occur if adequate precautions are not taken with re ard to the

fluid, the installation and the possibilities of the release of fluid,

vapors, and/or fumes.

d) Remove the coupling guard(s).

e) If the pump and driver are independently mounted to a com-

mon baseplate (not connected to each other with a motor sup-

port (83)) remove the spacer section of the coupling. Remove

the two bolts that fasten the bearing housing foot (9) to the

baseplate. Go to step (j).

f) If the pump and driver (motor or turbine) are connected togeth-

er by a “C” faced motor support (83) disconnect the power

supply from the driver. Place wood block and wedges under

the rear feet of motor sizes 143TC through 215TC or under

the motor support (83) of motors sizes 254TC through 365TC.

These blocks are to be positioned so as to support the weight of

the motor and the motor support (83) when they are separated

from the pump. Hook a lifting hoist to the lifting eye(s) of the

motor and take the slack out of the cable or chain. Make sure

that all of the components of the lifting apparatus are capable

of lifting the weight.

g) For units with motor sizes 143TC trough 215TC remove the

two bolts that fasten the motor support (83) to the baseplate.

For units with motor sizes 254TC through 365C remove the

two bolts that fasten the rear feet of the motor to the baseplate.

h) Remove the four bolts that fasten the motor support (83) to the

back of the pump. Be careful to support the weight of the motor

and motor support (83) as you are removing these bolts.

Carefully move the motor and motor support (83) assembly hor-

izontally and axially away from the pump guiding the assem-

bly to clear the pump coupling hub.

i) Remove the coupling elastomer from the coupling hub. The elas-

tomer may be in either the pump hub or the motor hub.

j) Drain all the fluids from all the auxiliary sub-systems (lubrication

cooling heating seal barrier etc.) that are connected to the

pump. Drain each fluid into a separate container. Use caution

required for each fluid after reading the MSDS (Material Safety

Data Sheet) for each.

k) Flush each sub-system with a compatible non-toxic non-haz-

ardous stable liquid. Drain into individual containers for each

fluid. Disconnect and remove all auxiliary piping.

l) Carefully bleed off any pressure remaining in the pump.

Pressure remaining in the pump will be dependent upon the

pressure in the system when the pump was stopped; the quality

type and condition of the isolation valves; the thermal expan-

sion values of the fluid and the pump material; and the change

in the vapor pressure of the fluid between the temperature at the

time the isolation valves were closed and the ambient tempera-

ture. Bleeding must be through a valved drain line piped to a

closed container mounted lower than the pump. The container

must be arranged with a relief passage to some point where

pressure and fumes will not be harmful to personnel. The con-

tainer must also have a level device so that determination can

be made that sufficient fluid has been drained to empty the

pump cavity and the volume of fluid that was contained in the

run of suction and discharge pipe between the isolation valves

and the pump. After the initial rush of fluid from the pump

relieves the pressure the drain valve can be opened further to

speed the draining operation. When fluid quits running into the

drain tank gage the volume to see if it is sufficient to have fully

drained the contents of the pump and the suction and dis-

charge pipes between the isolation valves.

If the system was constructed without any drain connections it

will be necessary to consult the designers of the system for safe

draining procedures.

m) Now drain any small piping that contains the fluid pumped

from all low points into the same container used to drain the

pump. Do not drain any other fluids (different then the

pumpage) into this container as they may not be compatible.

Personal injury death and/or equipment damage could occur.

WARNING:

Even thou h it mi ht appear that the cavity bein drained has com-

pletely drained, be extremely careful about openin the system

and/or openin the pump. If somethin solid in the pumpa e moves

to the vicinity of the drain connection, it could seal-off the drain and

maintain pressure in the cavity thou ht to have been drained. It is

also possible that the isolation valves are not sealin and therefore

R4140 DISASSEMBLY AND ASSEMBLY PROCEDURES

allowin liquid to flow from the system into the pump. Personal

injury, death and/or equipment dama e may occur if reat caution

is not exercised.

n) Because of the above possibility when you loosen the gasketed

joint at the back of the casing (5) loosen the casing nuts (5C)

only one full turn and then use the jack screws in the flange of

the cradle spacer (7) to break the gasket seal. If fluid and/or

pressure remains in the pump it will spray out now. Use

extreme caution wearing protective gear to avoid injury. Do

not proceed with disassembly until leakage ceases completely.

If leakage does not cease the isolation valves may not be seal-

ing. Note that if the pump was purchased without a drain the

pump will contain fluid which will flow out at the time the nuts

are loosened and the gasket seal is broken.

WARNING:

When you open the pump, the fluid will be exposed to the atmos-

phere and personnel in the area. For the safety of all involved, the

risk of exposure can be reduced by flushin the cavity that was just

drained with a compatible, non-toxic, non-hazardous, stable liquid,

before disassemblin the pump.

o) Remove the casing nuts (5C) and using a mechanical lifting

apparatus to support the weight pull the rotating unit from the

casing (5).

p) Flush the wetted parts now exposed with a compatible non-

toxic non-hazardous stable liquid.

q) Remove the gasket from the face of the casing (5) or the casing

back cover (22) dependent on which one the gasket may have

adhered to. The type of gasket and material of construction will

vary with service requirements. Attack by prying and then if

necessary layering off the old gasket with a sharp scraper

attempting to remove it in the largest possible pieces. Wear

heavy leather long sleeve work gloves when using the scraper.

Be careful to not scar the gasket contact surfaces of the casing

or the casing back cover. Wet the gasket before and during the

scraping operation to reduce the possibility of fibers becoming

airborne. Wear a respirator during this operation and until all

debris has been disposed of in a plastic bag. Remove all of the

gasket material down to clean metal surfaces on both parts that

contacted the gasket. Place all of the gasket residue in a plastic

bag seal the bag and dispose.

r) The rotating assembly of the pump can now be moved to a

more convenient location for further disassembly. Use mechani-

cal lifting equipment to move assemblies and components.

DISASSEMBLY PROCEDURE

REASSEMBLY PROCEDURE

WARNING:

Use only hi h quality tools.

Wear protective equipment as advised at the be innin of this

section.

Use mechanical liftin equipment to lift assemblies and components.

Do not hammer on any parts. Personal injury and/or dama e to

equipment may occur.

Do not attempt to manufacture parts or modify Dean Pump parts in

any manner. Death, personal injury, and/or dama e to equipment

may occur. One example of the above would be overborin the

stuffin box or the seal chamber, which removes metal that is

required to contain fluids. Removal of this metal reduces the pres-

sure containin capability of the part and may create a leak path

throu h the part. If the part separates two different fluids, mixin of

the fluids could cause an explosion. Water leaka e into a heat

transfer liquid is one example of an explosive possibility.

Replace all askets, seals, bearin s, and lubricants. Replace all parts

that have worn, corroded, eroded, or otherwise deteriorated.

Use only Dean Pump Division of Met-Pro Corporation parts.

To reassemble the pump perform the following steps:

a) Clean all parts thoroughly.

If needed press a new throat bushing (54) carefully into the casing

backcover (22).

c) If needed press a new casing backcover ring (6) into the casing

backcover (22).

If needed press a new

casing ring (6A) into the casing (5).

e) If the bearing housing foot (9) was removed bolt it back to the

bearing housing (26). Be sure that the dowel pins are in place

between the foot (9) and the housing (26). Tighten the cap-

screws to 50 ft. lb.

f) If the bull’s eye sight glass was removed apply pipe sealant to

the threads of a new bull’s eye sight glass and tighten it into the

side of the bearing housing (26). Torque to 50 ft. lb.

g) If the bearing housing vent (80) was removed install a new

vent (80) without thread sealant into the top of the bearing

housing (26). Tighten to 20 ft. lb.

h) Install new “O” rings onto the O.D. and into the I.D. of both the

labyrinth seals (76 and 76A). Lubricate the “O” rings on the

O.D. of both labyrinths.

i) Press the front labyrinth seal (76) into the seal ring (27).

j) Press the rear labyrinth seal (76A) into the bearing end cover

(28). The “expulsion port” (the slot in the O.D.) of the labyrinth

(76A) must be positioned at the bottom of the end cover. This

will be inline with the machined “oil return” slot in the end

cover (28).

k) Press the bearings (25 and 25A) onto the pump shaft (29).

Press only on the inner races of the bearings. Do not press on

the outer races. The thrust bearing is a matched pair of angular

contact bearings and must be assembled “back to back”. See

the illustration on page 15. Be sure to place the snap ring (75B)

over the shaft before pressing on the last bearing(s).

I) Place a new bearing lock washer (31A) onto the pump shaft

(29). Tighten the bearing lock nut (31) against the lock washer

to 75 ft. lb. while holding the shaft (29) against rotation with a

hook spanner wrench in the keyway. Another way to keep the

shaft from turning is to place the coupling hub onto the shaft

and hold it with a wrench. Bend one of the tabs of the lock-

washer (31A) into the corresponding slot in the locknut (31).

m) Lubricate the O.D. of the bearings (25 and 25A) and the bores

of the bearing housing (26). Slide the shaft (29) bearing (25

and 25A) assembly into the rear of the bearing housing (26).

After the radial bearing (25) has passed through the rear bore

of the housing reach into the opening with snap ring pliers

and place the retaining ring (75B) into the rear bore of the

housing. Install the retaining ring with the opening in the ring at

the bottom of the housing so that it is centered with the oil return

groove in the housing. The ring does not have to be in it’s

groove. The bearing housing is machined with a long chamfer

that allows the thrust bearing (25A) to push the ring into it’s

groove as the shaft assembly is pushed into the bearing hous-

ing. The shaft may now be fully inserted until the thrust bearing

(25A) is firmly against the retaining ring (75B) and the retain-

ing ring is firmly in it’s groove.

n) Lubricate the end cover gasket (77B) which is an

“O” ring.

Place the end cover gasket (77B) onto the end cover (28).

Lubricate the I.D. of the rear labyrinth seal (76A) which is in the

end cover (28). Lubricate the area of the pump shaft (29) just

behind the thrust bearing (25A) where the rear labyrinth seal

(76A) will be mounted. Slide the bearing end cover (28) labyrinth

seal (76A) assembly carefully over the end of the pump shaft (29).

Be careful that the “O” ring in the I.D. of the labyrinth seal (76A)

does not contact the keyway of the shaft (29) and become dam-

aged. Placing a piece of plastic electrical tape over the keyway

before this assembly operation will give a measure of protection.

Rotate the end cover (28) so that the machined “oil return slot” is

towards the bottom of the bearing housing (26). Seat the end

cover fully into the bearing housing and tighten the end cover bolts

to 25 ft. lb.

o) Re-install the bearing housing oil cooler (109) into the bearing

housing (26). Install the oil cooler (109) into the open 1” NPT con-

nection and carefully guide the end of the tubing through the tub-

ing connector on the opposite side of the bearing housing (26).

Apply pipe sealant to the 1” male pipe threads and tighten the 1”

tube connector into the bearing housing (26) with a torque of 50

ft. lb. The ferrules used in these tube connectors are plastic to

enable disassembly and re-assembly without damaging the cooling

tube. When tightening these connectors tighten to only 5 ft. lb.

p) Lubricate the I.D. of the front labyrinth seal (76) which is in the

seal ring (27). Lubricate the area of the pump shaft (29) just in

front of the radial bearing (25) where the front labyrinth seal (76)

will be mounted. Slide the seal ring (27) labyrinth seal (76) assem-

bly carefully over the end of the pump shaft (29). Be careful that

the “O” ring in the I.D. of the labyrinth seal (76) does not contact

the keyways of the shaft (29) and become damaged. Press the

seal ring (27) labyrinth seal (76) assembly into the front of the

bearing housing (26). The “expulsion port” (the slot in the O.D.) of

the labyrinth (76) must be positioned so that it is towards the bot-

tom of the bearing housing (26)

q) Dean pumps are made with a lapped metal-to-metal joint between

the shaft sleeve (10) hook and the locating shoulder on the shaft

(29) to prevent liquid leakage under the shaft sleeve. The following

instructions should be carefully observed when the shaft is reassem-

bled to the shaft:

1. Apply a small amount of 280 grit lapping compound (simi-

lar to automobile valve grinding compound) to the inside

shoulder of the shaft sleeve hook.

2. Slide the shaft sleeve (10) onto the shaft. Do not install the

shaft sleeve key (10K).

3. Rotate the shaft sleeve repeatedly by hand in its place on

the shaft until the markings on both shaft and sleeve hook

show that complete metal-to-metal contact has been made.

4. Remove the shaft sleeve and flush all lapping compound

from the sleeve and shaft. Reassemble the shaft sleeve on

the shaft with the shaft sleeve key (10K) in place.

r) Assemble the cradle spacer (7) to the bearing housing (26).

Tighten bolts to 50 ft. lb.

s) If the pump stuffing box is to be packed slide the packing

gland (13) over the shaft sleeve and back against the front

labyrinth seal (76).

t) If the pump is equipped with a mechanical seal assemble the

seal parts on the shaft sleeve at this time. See separate mechan-

ical seal installation instructions.

u) Slide the casing back cover (22) carefully into place and secure

it to the cradle spacer with the two capscrews. Be especially

careful not to damage mechanical seal parts. Tighten bolts to

30 ft. lb.

v) Place the impeller key (4) into the shaft (29) keyway and slide

the impeller (3) into position on the shaft (29) Drive the impeller

lockwasher dowel (12C) into the impeller washer (12A) until it

is flush with the side of the washer that has a blind hole . Place

the impeller bolt (12) through the impeller lock washer (12B)

and then the impeller washer (12A) so that the protruding part

of the impeller lock washer dowel (12C) is away from the head

of the impeller bolt (12). Screw the impeller bolt (12) into the

shaft (29) while guiding the protruding impeller lock washer

dowel (12C) into the keyways of the impeller (3) and the shaft

(29). Tighten the impeller bolt (12) to 60 ft. lb.

Use a drive pin punch to bend the edge of the impeller lock

washer (12B) into the blind hole in the impeller washer (12A).

Use a chisel to bend the side of the impeller lock washer (12B)

up against a flat of the impeller bolt approximately 90° from

the blind hole.

w) Replace the coupling key into the keyway at the coupling end

of the pump shaft (29).

x) If the pump and driver are independently mounted to a com-

mon baseplate place the pump coupling hub (including the

four axial bolts) onto the pump shaft (29) flush with the end of

the pump shaft and tighten the set screws. Go to step (z).

y) If the pump and driver are connected by a “C” faced motor

support place the pump coupling hub onto the pump shaft

(29) to the location noted below and tighten the set screws.

For use with motor sizes 143TC and 145TC place pump hub

to overhang pump shaft by 1/16”.

For use with motor sizes 182TC and 184TC place pump hub

so that the pump shaft protrudes 3/16”.

For use with motor sizes 213TC and 215TC place pump hub

to overhang pump shaft by 5/16”.

For use with motor sizes 254TC and 256TC place pump hub

z) If the pump shaft is to be sealed with packing do so now. See

“Installation and Maintenance of Shaft Compression Packing”

section of this manual.

aa) Rotate the pump shaft by hand to be sure there is no internal

rubbing or binding.

ab) The partial assembly can now be taken to the assembly site.

Use proper lifting equipment and methods.

ac) Place a new casing gasket (77) into the casing (5). Unscrew the

two casing jacket bolts in the flange of the cradle spacer (7)

until neither protrudes from the flange towards the casing.

Inspect the face of the casing where the jack screws made con-

tact during disassembly and carefully remove any burrs with a

file.

ad) Using a hoist to lift and position the partial pump assembly

install it into the pump casing (5). Be careful to align the assem-

bly with the casing so that the impeller (3) slides freely into the

close clearance of the casing ring (6A). Screw the casing stud

nuts (5C) by hand into the casing studs (50) but do not tighten

them yet.

ae) If the pump and driver are independently mounted to a com-

mon baseplate go to step ap).

af) If the pump and driver are connected by a “C” faced motor

support (83) place wood blocks and wedges under the bear-

ing housing (26) to support the pump.

ag) Place the motor coupling hub onto the motor shaft to the loca-

tion noted below and tighten the set screws.

spacer section to the motor hub.

ai) Place the coupling elastomer into the pump coupling hub.

aj) Lift the motor and motor support (83) assembly with a hoist

and position it so that the motor support pilots onto the end of

the bearing housing (26) and so that the motor end of the cou-

pling engages the coupling elastomer that is retained in the

pump hub of the coupling. It may now be necessary to rotate

the motor shaft slightly to allow the coupling components to

engage. Install the bolts that retain the motor support (83) to the

bearing housing (26). Hand tighten the bolts.

ak) Remove all blocks and wedges while maintaining support with

a hoist. Gently and carefully lower the hoist enough to allow

the weight to seat the supporting feet onto the baseplate. When

the support feet make full contact with the base lightly tighten

the casing stud nuts (5C) and the bolts that retain the motor sup-

port (83) to the bearing housing (26).
