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

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.

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.

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.
