loss or damage.
All installation, operation, and maintenance must be done by thor-
oughly 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 damage and such damage noted
on the bill of lading before it is signed. Claims for shipping damage
must be filed against the carrier.
Care should be exercised in unloading and handling 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,
sizing, sealing, pressure containing capability, head/capacity capa-
bility, and temperature capability with respect to the required
service. Consult your Dean Pump sales engineer with all the service
requirements and a full description of the existing pump (including
the serial number), seal, and sub-systems so that we can assist you in
a successful reapplication.
PUMP FOUNDATION
The pump foundation provides rigid support to the baseplate and
maintains the exact 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.
NOTE: Refer to MC 1.2.34 FBP when Dean FRP baseplates are used.
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
Alignment’’ on page 5.
4) Grout the baseplate. Do not grout the baseplate to the founda-
tion until the pump and driver are correctly aligned. Channel
type baseplates are made with open ends to allow easy grout-
ing and do not require grouting holes in the baseplate.
Fabricated structural steel baseplates are provided with grout-
ing 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 Discharge Piping’’ on
page 5. 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 “forcing”, improper flange bolting, and/or
misalignment may cause failure of the pumping unit, flanges, piping
and/or fluid (pumpage) release which could cause personal injury,
death, and/or damage 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 Cooling
Requirements” on page 10.
WARNING:
Make sure that all piping 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 damage to this
and/or other equipment.
Install pressure relief valves in any cavities that could be subjected to
pressures in excess of the allowable working pressure. Explosion,
personal injury, death, and/or damage to this and/or other equip-
ment may occur if pressure exceeds allowable.
One example of the above would be the cooling 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 degrees 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
may have forced the pump out of alignment. If so, correct the
TYPICAL FOUNDATION LAYOUT

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. NOTE: Refer to
MC 1.2.34 FBP when Dean FRP baseplates are used.
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 suc-
tion 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
important 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 fil-
ter installed in the suction line is recommended. Commercially
able to the pump and should be considered at the time the system
is designed.
NOTE: See page 26 for Installation of pHP self-priming pumps.
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
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 alignment must always be checked and corrected before the
baseplate is grouted to the foundation and again 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 align the unit will result in
vibra tion, short bearing 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. Any and all loads upon the
pump must be with-in the maximum allowable values given in the
section titled “Allowable Nozzle Loads” on page 6.
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 alignment must always be checked and correct-
ed at the operating 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. Rotate the shaft on
which the dial indicator is mounted, allowing the indicator button
to move on the stationary coupling hub. The indicator dial move-
ment will show the difference in distance between the two hubs.
This indicates the amount of angular misalignment between the
hubs and therefore the shaft axes. Good practice suggests align-
ment to within 0.002" T.l.R.
available strainers or filters as recommended by their manufactur-
ers can do an excellent job. In addition, special filtering and
mechanical seal flushing may be required. Consult your Dean rep-
resentative. Suction line screens or strainers may usually be
removed when, after several days of use, no dirt has been collect-
ed and the system is clean.
Remember that screens and filters in the suction line are restrictive
devices which reduce the net positive suction head (NPSH) avail-
TYPICAL PUMP PIPING

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. 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 misalignment is
of major proportions, the baseplate has been improperly installed
on the foundation and must be releveled before proceeding with
alignment.
After each change, it is necessary to recheck both angular and
offset alignment of the coupling. After driver is aligned to the
pump, tighten all hold-down bolts and then recheck alignment.
Allowable error of shaft alignment is somewhat dependent on
the coupling type. However, the closer the running alignment,
the better the running life will be.

Notes:
1) The loads shown in Tables 1 through 4 are for a pump
mounted upon a fully grouted metal base plate with anchor
bolts.
2) The loads given in Tables 1 through 4 are for pumps con-
structed of 316 Stainless Steel when operated between
–20°F. and 100°F.
3) The temperature for a corresponding allowable nozzle load
is the temperature of the pumped liquid.
4) For an individual(single) load, the value of the applied load
must not exceed the maximum allowable value, for that
location, given in Table 1. i.e. The applied load divided by
the allowable load must be less than or equal to 1.0.
5) For a combination of more than one force and/or moment,
the applied loads must not exceed any limit of any Equation
(Sets 2 through 5) or any table (2 through 4).
6) When combining loads, the absolute value of any individual
load must not exceed the value given in Table 1.
7) The loads in the tables must be multiplied by adjustment
factors when applicable. The lowest correction factor must
be applied when more than one adjustment factor is
involved. There are cases where one adjustment factor is
applied in Table 2 and another adjustment factor is applied
to Tables 3 and 4.
Adjustment of allowable loads is required for:
Pump constructed of a material other than 316 S/S.
Pumping Liquid at temperatures above 100°F.
The base plate is not grouted.
The base plate is nonmetallic.
INSTRUCTIONS FOR USE OF ALLOWABLE LOADS
1) Determine the applied nozzle loads from the suction and dis-
charge piping systems.
2) Use the correction factor from Table 5 for the pump material
and operating temperature. For intermediate temperatures not
shown in Table 5 linear interpolation is permitted. Multiply the
values in Table 2 (For the applicable pump size) by the correc-
tion factor to obtain the allowable values.
3) If the base plate is metal, fully grouted, and anchored, evaluate
the values of the de-rated Table 2 to see if any value is lower
than the corresponding value in Table 1. If so, substitute the
lower of the values into Table 1. No corrections are needed to
Tables 3 and 4. Go to step 7.
4) If the base plate is un-grouted metal that is anchored down, use
the corrected values of Table 2 from Step 2 above and 80% of
the values in Tables 3 and 4. After adjusting the values in
Tables 3 and 4, if the absolute values of any of them or the
adjusted values of Table 2 (from Step 2 above) are lower than
the corresponding values in Table 1, substitute the lower of the
values into Table 1. Go to step 7.
5) If the base plate is grouted, anchored, and non-metallic, multi-
ply the original values of Table 2 by 80%. Compare these cor-
rected values with the Table 2 corrected values of Step 2
above. Use the lesser of the two corrected values as the Table 2
corrected values. Multiply the values of Tables 1, 3, and 4 by
80%. If any of the values of the de-rated table 2 are lower than
the corresponding values in the de-rated Table 1, substitute the
lower of the values into Table 1. Go to step 7.

PUMP COOLING REQUIREMENTS
10
Pumps are furnished with optional seal chamber jacket, jacketed
casing, jacketed mechanical seal gland, and bearing housing cool-
ing coil according to the pump service.
SEAL CHAMBER COOLING
Cooling is recommended under these conditions:
1) With a mechanical seal when the pumping temperature is
above 350°F. Individual plant specifications may require cool-
ing above 250°F. Specific applications or liquids may require
cooling at lower temperatures.
2) With a mechanical seal when pumping liquids of 0.75 specific
gravity, or less, when the pumping temperature permits further
cooling.
3) With packing at temperatures above 250°F.
MECHANICAL SEAL GLAND COOLING
Mechanical seal gland cooling is generally applied under the same
conditions as those for seal chamber cooling. For pumping tempera-
tures only slightly above those requiring seal chamber cooling,
gland cooling may not be required on a specific application.
BEARING HOUSING COOLING
Cooling of the bearing housing is applied to cool the lubricating oil
and bearings. 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 contamina-
tion of the oil.

INSTALLATION OF COOLING AND/OR SEAL CONNECTION PIPING TO THE PROPER CONNECTIONS IN MANDATORY. PUMP JACKET COOL-
ING WATER INSTALLED TO THE SEAL CONNECTIONS WILL RESULT IN INJECTION OF WATER INTO THE PUMPAGE WHICH MAY CAUSE SERI-
OUS CONTAMINATION OF THE PRODUCT AND HEAVY CORROSION. DEPENDING ON TEMPERATURE, IT MAY ALSO CAUSE A VIOLENT
STEAM EXPLOSION IN THE PUMP OR ASSOCIATED PIPING OR EQUIPMENT WITH EXTREME HAZARD TO PERSONNEL.
IMPORTANT WARNING
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 Seal
Chamber Cooling, and Bearing Housing Cooling Coil, 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 customer 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.
The relief valve is installed between the jacket and the flow control
valve to relieve any dangerous pressure that could develop in the
jacket. Pipe each outlet from the flow control valve to an open sight
drain or through a suitable flow indicating device into the plant cool-
ing water return system.
In no case should the outlet be piped into the municipal water
system.
Cooling jacket piping should be run to provide inlet water at the low-
est jacket connection and outlet from the highest connection.
COOLING WATER FLOW RATES
Seal chamber jacket cooling water flow rates are related to pumping
temperature. A rate of 2 to 5 GPM is advisable, the higher rate at a
pumping temperature of 500°F.
Mechanical seal gland cooling flow should be adjusted to about 1
/2
GPM.
Bearing housing cooling coil water flow rate should be adjusted to
1
/2GPM. This will maintain the bearing housing temperature in the
120°F to 200°F range. The pump may be operated without bearing
housing cooling if experience in the particular installation shows that
bearing housing temperatures do not rise above 200°F.

The optional seal chamber, mechanical seal gland, and pump
casing jackets may be used to provide pump heating. The jack-
ets are good for pressure to 125 psig and may be used with
steam or heat transfer liquids. Series or parallel piping of the
seal chamber and pump casing jackets may be used. The
mechanical seal gland jacket piping should be run indepen-
dently so as not to be a flow restriction.
When steam is used as the heating medium, inlet piping should be
run to the highest jacket connection and outlet should be from the
lowest connection to allow condensate to drain.
The casing and backhead may be lagged to minimize heat loss.
Remember that seal chamber temperatures above 350°F may
cause early failure of mechanical seal parts.
PUMP HEATING REQUIREMENTS
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 pump is fitted with a “Bull’s Eye” type oil level indicator, and fill
openings on both sides of the bearing housing. If it would be easier
to see, the “Bull’s Eye” can be removed and repositioned on the
opposite side of the bearing housing. Fill the sump through one of
the NPT fill openings on the side of the bearing housing until the oil
level reaches the center of the “Bull’s Eye” level indicator. The oil
must be maintained at this level during operation.
If the optional automatic oiler was supplied, it was packed sepa-
rately for pump shipment to avoid damage. Install the oiler into the
1” NPT tapped hole on either side of the bearing housing. Screw
the oiler reservoir from the top of the “Bull‘s Eye” housing, invert it,
fill it with oil, and reinstall it into the housing.
The oil should be drained and replaced at regular intervals, the
intervals depending on the atmospheric conditions (dust, soot, cor-
rosive 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 are shipped from the factory without oil in the bearing housing.
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 filling 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 containing cavity is sealed. Normally this sealing is
accomplished with shaft packing or a mechanical face seal. See that
all of the connections into the pressure containing cavity are sealed
or connected to a related piping system that also has all possible
leak paths sealed. Do not plug unused jacket cavities, as this could
develop dangerous pressure build-up. Use a wrench on all bolted
joints to apply torque to assure that all gaskets are sealed in a tight
joint. Check to see that all threaded pipe connections are also tight
enough 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 atmospher-
ic 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 available
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 allowing the pump to come up to speed. 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 direc-
tion of rotation to be observed. If the pump is fitted with the optional
“C” face motor support (83), the shaft coupling will be installed,
causing the pump shaft to rotate with the motor shaft. Be careful that
you push the start and stop buttons essentially at the same time so
that the unit does not come up to speed. The impeller is threaded on
to the pump shaft, and will unscrew causing damage if operated in
reverse direction. A direction of rotation arrow is shown on the front
of the pump casing. If rotation is incorrect, change the wiring con-
nections and recheck rotation. Operating the pump in reverse rota-
tion may cause extensive damage.
WARNING:
Lock-out the power to the driver (motor, turbine, engine, etc.)
Install the shaft coupling spacer. Be sure that you install all the
retaining devices and bolts and that they are tight. Read and comply
with the coupling manufacturers instructions. Personal injury, death,
and/or equipment damage could occur if the coupling spacer is not
properly installed. Remove all debris and tools from the area near
the shafts and the shaft coupling. Do this to assure that nothing is

caught and thrown by the rotating parts when the pump is started.
Bolt the coupling guard securely into place, checking to assure that it
is not contacting any parts that will rotate when the pump is started.
OPERATING
WARNING:
Before starting the unit, see that all personnel are a safe distance
away from all possible hazards, that all sub-systems are connected
and operating, that all debris has been removed, that the shaft cou-
pling guard 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 damage, and/or loss of product
(pumpage) is likely to occur. If your system is operated where it is
possible for all outlets of the discharge from the pump to be closed
while the pump is still operating, a modification of the system needs
to be made to assure a continual flow of pumpage through the
pump. NOTE: Some people have a belief that a bypass line from the
discharge 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 dangerous heat build up within the pump
casing. The liquid in the pump will heat up and this may result in
high pressure in the pump in a short time. Such pressure may result
in a rupture of the pressure-containing parts and cause severe haz-
ard to personnel and/or damage to the system.
A centrifugal pump should never be run without liquid In the casing.
Extensive damage may result, particularly to the mechanical seal or
compression packing. When the pump is equipped with a mechani-
cal seal, vent the pump seal chamber through 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 dis-
charge valve closed without heating up dangerously. During the first
several minutes of operating watch the pump carefully for overheat-
ing, vibration, and other abnormal conditions. If trouble develops,
stop pump at once and correct the problem.
These points must be checked after pump installation and before
starting 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 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 spacer. 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 diffi-
culties 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.
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 fol-
lowing 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 suc-
tion flange or the top edge of the bearing 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.

DISASSEMBLY AND RE-ASSEMBLY PROCEDURES
WARNING:
Work must be performed only by thoroughly trained and qualified
personnel to assure quality repair and to reduce the possibilities of
injury to personnel and/or damage 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 pumping 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 pumpage can be reduced by flushing the entire
system with a compatible, nontoxic, non-hazardous, stable liquid
before opening the pump or the system. In all cases, where the sys-
tem is flushed or not, use the utmost care around the pumpage and
the pumping system.
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 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 breathing apparatus face shields, heavy long sleeve
rubber gloves, rubber apron, hood, and possibly more, dependent,
of course, on the properties of the fluids involved and the installed
drain and vent piping arrangement. Personal injury and/or death
can occur if adequate precautions are not taken with regard 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
common baseplate (not connected to each other with a motor
support (83)), remove the spacer section of the coupling.
Remove the two bolts that secure 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. Remove any conduit and/or piping from
the driver. Place wood blocks and wedges, under the rear feet
of motors sizes 143TC through 215TC, or under the motor sup-
port (83) of motors sizes 254TC thru 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 through 215TC, remove the
two bolts that fasten the motor support (83) to the baseplate.
For units with motor sizes 254TC trough 365TC, 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
elastomer 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 than the
pumpage) into this container as they may not be compatible.
Personal injury, death, and/or equipment damage could occur.
WARNING:
Even though it might appear that the cavity being drained has com-
pletely drained, be extremely careful about opening the system
and/or opening the pump. If something solid in the pumpage moves
to the vicinity of the drain connection, it could seal-off the drain and
maintain pressure in the cavity thought to have been drained. It is

18
also possible that the isolation valves are not sealing and therefore
allowing liquid to flow from the system into the pump. Personal
injury, death and/or equipment damage may occur if great caution
is not exercised.
n) Hook a lifting hoist to the lifting eye in the top of the bearing
housing (26) and take the slack out of the cable or chain. Make
sure that all of the components of the lifting apparatus are capa-
ble of lifting the weight. Because of the above possibility, when
you loosen the gasketed joint at the back of the casing (5),
loosen the casing capscrews (5D) or the casing stud nuts (5C)
(pH3170) only one full turn. Use jack screws in the holes pro-
vided in the flange of the cradle spacer (7), or the bearing
housing (26) of the pH2110, 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 com-
pletely. If leakage does not cease, the isolation valves may not
be sealing. Note that if the pump was purchased without a
drain, the pump will contain fluid which will flow out at the time
the bolts (or 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 flushing the cavity that was just
drained with a compatible, non-toxic, non-hazardous, stable liquid,
before disassembling the pump.
o) Remove the casing capscrews (5D) or the casing stud nuts (5C)
(pH3170) 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.
Wet the gasket before and during the scraping operation to
reduce the possibility of fibers becoming airborne. Wear a res-
pirator during this operation and until all debris has been dis-
posed 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
To further dismantle the pump, perform the following steps in the
sequence shown:
WARNING:
Use only high quality tools.
Flush parts as disassembled to remove hazardous residue from the
pumpage and/or sub-system fluids.
Wear protective equipment as advised at the beginning of this
section.
Use mechanical lifting equipment to lift assemblies and components.
Do not apply heat to parts to assist in disassembly. Explosion could
occur causing personal injury, death, and/or damage to equipment.
Do not attempt to drill, saw or otherwise cut parts to remove them.
Explosion and/or fuming could occur causing personal injury, death,
and/or equipment damage.
Do not hammer on any parts. Personal injury and/or damage to
equipment may occur.
a) Remove gland stud nuts (15) and slide gland (13) away from
seal chamber.
b) Remove packing from stuffing box if pump is packed. Use
packing extractor.
c) Remove the impeller (3) using a wrench on the flats of the pump
coupling hub to rotate the pump shaft (29) while holding the
impeller against turning. The impeller has a hex boss to aid
removal. The impeller thread is right hand.
d) Remove the two capscrews that secure the casing back cover
(22), to the bearing housing (26) of the pH2110 and
pHP2110 series pumps, or to the cradle spacer (7) of all other
series pumps. Carefully remove the casing back cover (22) axi-
ally, so as to not damage the pump shaft (29), shaft sleeve
(10), or mechanical seal rotary (95B).
e) If the pump is equipped with a mechanical seal, loosen the set
screws that retain the seal and remove the mechanical seal
rotary (95B). Remove the mechanical seal stationary (95A) and
gland (13). Remove the mechanical seal stationary (95A) from
the gland (13).
f) Remove the impeller gasket (77A) from the end of the pump
shaft (29) or from the impeller (3) depending on where the
gasket remained when the impeller (3) was removed.
g) Remove the shaft sleeve (10) and the sleeve key (10K) from the
pump shaft (29).
h) If the pump is of the pH2140, pHP2140, pH 2170, pH 3170,
or pH2180 series, and if you desire to do so, you can remove
the spacer cradle (7) from the bearing housing (26) by remov-
ing the four capscrews that hold these two pieces together.
Normally there is no reason to remove the spacer cradle (7).
i) Remove the pump coupling hub from the pump shaft (29).
j) If the pump is fitted with an optional oil cooler (109), remove it
at this time. Remove the “1
/2" tube X 1 /2" male pipe thread” fit-
ting from one end of the oil cooler (109). Remove the tubing nut
and tubing ferrule from the “1
/2" tube X 1" male pipe thread”
fitting that is in the bearing housing (26) on the same side that
you removed the first fitting. Unscrew the “1
/2" tube X 1" male
pipe thread” fitting, that is in the opposite side of the bearing
housing (26), from the bearing housing and pull the oil cooler
(109) out through the 1" NPT opening.
k) Remove the bearing end cover capscrews (28A). Pull the pump
shaft (29), bearings (25 & 25A), and bearing end cover (28)
as an assembly, axially, from the bearing housing (26).
