WARNING
Rea the instruction manual completely before installing, filling, oper-
ating, or maintaining this equipment.
Obtain, rea an hee the MSDS (Material Safety Data Sheet) for
the flui s being han le 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

INSTALLATION
Always wear the appropriate protective apparel when working on
or aroun the pumping equipment. Safety glasses with si e shiel s,
heavy work gloves (use insulate work gloves when han ling hot
items), steel-toe shoes, har hat, an any other protective gear as
nee e for protection. One example of other gear woul be breath-
ing apparatus when working near toxic materials. Use lifting
evices, manufacture expressly for the purpose of lifting, to move
the pumping machinery. Do not attempt to lift the assembly or its
components manually. Use only evices with lifting capabilities in
excess of the weight of the unit being lifte . Inspect straps, chains,
hooks, etc. for amage an lifting capability before use. Lift only at
the center of gravity.
Personal injury, eath, an /or equipment amage coul occur if
goo lifting practices are not use .
APPLICATION AND REAPPLICATION
At the time of installation, the equipment receive shoul have
alrea y been selecte for the service require . You must rea the
paperwork for the installation an check the serial number of the
pump to assure that you are installing the correct pump into the ser-
vice for which it was selecte .
Many pumps look i entical from the outsi e but can be ma e of if-
ferent materials an /or be constructe ifferently insi e. Personal
injury, eath, equipment amage, pro uct (pumpage) amage,
an /or pro uct loss coul occur if the incorrect pump is installe .
Do not transfer an existing pump to any other service con itions until
you have thoroughly reviewe the pump construction, materials, siz-
ing, sealing, pressure containing capability, hea /capacity capabili-
ty, an temperature capability with respect to the require service.
Consult your Dean Pump sales engineer with all the service require-
ments an a full escription of the existing pump (inclu ing the serial
number), seal, an sub-systems so that we can assist you in a suc-
cessful reapplication.
PUMP FOUNDATION
The pump foun ation provi es rigi support to the baseplate an
maintains the alignment of the pumping unit. Baseplates are
esigne to rigi ly support the pump an river without vibration or
istortion only when they are properly set, levele , an secure to
the foun ation.
The purchaser may elect to mount the pump without grouting the
baseplate. In any case the baseplate must be fully supporte by the
customer’s mounting means to prevent vibration an istortion.
BASEPLATE MOUNTING AND ALIGNMENT
The sequence of mounting which must be observe for proper base-
plate an pump mounting is:
1) Place baseplate, with pump an river mounte thereon, on the
pump foun ation.
2) Use we ges un er the baseplate e ges, at each foun ation
bolt, to properly support an level the unit. Check this with a
spirit level. Pull own the baseplate mounting bolt nuts tightly
an recheck for level. Correct if necessary.
3) Align the river to the pump (except for pumps with optional
“C” face motor support). 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. Channel
type baseplates are ma e with open en s to allow easy grout-
ing an o not require grouting holes in the baseplate.
Fabricate structural steel baseplates are provi e with grout-
ing holes. Fill the entire voi un er the baseplate with grout an
firmly embe the baseplate e ges.
5) Connect the suction an ischarge 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 an the correct material per ASME/ANSI B16.5, in
every bolt hole. Tighten all bolts evenly. Use only new
uncorro e 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 an river alignment (except for pumps with
optional “C” face motor support) to ensure that no istortion of
the pump unit has been cause by piping strain. Correct
piping if misalignment has occurre an again align pump an
river.
7) Connect all other (auxiliary) piping necessary for safe an
successful operation of the equipment in the specific service
con itions 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 river (motor,
turbine, or engine) an pump shafts. Installation of piping 3
TYPICAL FOUNDATION LAYOUT

may have force the pump out of alignment. If so, correct the
piping to remove the istorting loa , an realign the pump
an river.
9) The pump an river alignment must again be checke
(except for pumps with optional “C” face motor support) at the
operating temperature an alignment correcte un er the hot
con ition.
10) After about two weeks of normal pump operation the pump
an river alignment shoul again be checke (except for
pumps with optional “C” face motor support) un er the hot
con ition. If alignment is still correct, the river feet may be
owele to the baseplate. If the alignment has change ,
realign the unit an recheck after two weeks.
SUCTION AND DISCHARGE PIPING
Suction an ischarge nozzle sizes of Dean pumps are selecte for
proper performance of the pumping unit an are not inten e to
etermine the suction an ischarge pipe sizes. Pipe sizes must be
etermine by the user base on the system requirements.
Suction piping shoul have a minimum friction loss an thus shoul
be as short an straight as possible with a pipe iameter as large as
economically feasible for the flow rate han le . Suction piping
shoul never be smaller in iameter than the suction nozzle size.
When the suction piping is larger than the suction nozzle size an
eccentric re ucer is require at the suction flange an must be
installe with the taper locate on the un ersi e to eliminate air or
vapor pockets. The section of piping attache to the suction flange
of the pump shoul be straight for a length of eight pipe iameters
or more.
Discharge piping may be the same size as, larger, or smaller than
the ischarge nozzle as the system flow may eman .
In new installations or rebuilt systems, irt, pipe scale, wel ing slag,
an general construction ebris may get into the piping. It is impor-
tant to prevent this material from entering the pump an amaging
pump parts, mechanical seal faces, or seal chamber packing.
Mechanical seal parts are especially subject to amage even by
very small particles. To prevent amage, a strainer or filter installe
in the suction line is recommen e . Commercially available strainers
or filters as recommen e by their manufacturers can o an excel-
lent job. In a ition, special filtering an mechanical seal flushing
may be require . Consult your Dean representative. Suction line
PUMP AND DRIVER ALIGNMENT
Proper running life of a pump an river unit epen s on the accu-
racy with which the axis of the river shaft coinci es with the axis
of the pump shaft when the unit is running. Although pumps an
rivers are check aligne at the factory, this is only to confirm that
the unit can be aligne in the fiel an han ling uring shipment
an installation will cause the alignment to change. The pump and
driver ali nment must always be checked and corrected (except for
pumps with optional “C” face motor support) 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 lowe , no ifficulties in making the alignment shoul be experi -
ence . Failure to properly ali n the unit will result in vibra tion,
short bearin life, an re uce mechanical seal or shaft packing
life.
Pumps are not constructe to be use as pipe anchors. Both suc-
tion an ischarge piping must be supporte in epen ently of the
pumping unit an thermal expansion joints provi e to guar
against expansion loa s on the pump. Pipes shoul be anchore
between the expansion joint an the pump an as closely to the
pump as possible. Failure to provi e proper piping support an
expansion joints may impose strains on the pump ing unit which
will result in serious misalignment. Maximum allowable piping
loa s are shown on page 5 in this manual.
No allowance for thermal expansion is ma e for motor riven
units in mounting the river. Allowance for turbine mounting
shoul be in accor ance with the turbine manufacturer’s recom-
men ations. 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 kin s. 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 an offset misalignment
are present.
Coinci ent alignment of the river an pump shaft is measure at
the faces of the coupling hubs. Because of the variety of coupling
types furnishe at customer’s request, the proce ure here given is
general in nature but may be applie by simple a aption to most
coupling types.
The first step is to remove the spacer from the coupling. To one of
the remaining coupling hubs, firmly seate on the shaft, attach a
ial in icator. Let the in icator button ri e on the face of the other
coupling hub an near the outsi e iameter. See illustration on
page 5. Rotate the shaft on which the ial in icator is mounte ,
allowing the in icator button to move on the stationary coupling
hub. The in icator ial movement will show the ifference in is-
tance between the two hubs. This in icates the amount of angular
misalignment between the hubs an therefore the shaft axes.
Goo practice suggests alignment to within 0.002" T.l.R.
TYPICAL PUMP PIPING
screens or strainers may usually be remove when, after several
ays of use, no irt has been collecte an the system is clean.
Remember that screens an filters in the suction line are restrictive
evices which re uce the net positive suction hea (NPSH) available
to the pump an shoul be consi ere at the time the system is
esigne .

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 an moments calculate from these force equations or the tabulate moment tables are
those resulting in a maximum of .010 inch movement of the shaft measure at the shaft coupling when the pump is
mounte on its baseplate an that baseplate is fully bolte to a properly esigne foun ation an is fully groute
in place. For a full iscussion see API Stan ar 610, 5th E ition.

To check the offset alignment, mount the ial in icator as above
except with the in icator button on an outsi e iameter of the sta-
tionary coupling hub. See illustration below. Rotate the shaft on
which the ial in icator is mounte , allowing the in icator button to
ri e on the outsi e iameter of the stationary hub. The in icator ial
move ment will show the ifference in the center locations of the two
shafts. Goo practice suggests alignment to within 0.002" T.I.R.
Angular an offset alignment is a juste by placing thin metal shims
un er the river mounting feet to bring the rive into exact alignment
with the bolte own 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.
After each change, it is necessary to recheck both angular an offset
alignment of the coupling. After river is aligne to the pump, tight-
en all hol - own bolts an then recheck the alignment.
Allowable error of shaft alignment is somewhat epen ent on the
coupling type. However, the closer the runnin ali nment, the better
the runnin life will be.

PUMP COOLING REQUIREMENTS
Pumps may be furnishe with the following jackets or cooling coil:
1) Stuffing box
2) Mechanical seal glan (optional)
3) Casing pe estals (optional)
4) Bearing housing cooling coil (optional)
Cooling is recommen e un er the following con itions:
STUFFING BOX COOLING
1) With a mechanical seal when the application requires
cooling.
2) With a mechanical seal when pumping liqui s 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 epen s on the liqui pumpe an the pumping
temperature.
BEARING HOUSING COOLING
At pumping temperatures below 500°F, such cooling is rarely
necessary. Excessive cooling of the bearing housing may lea
to early bearing failure from moisture con ensation an contami-
nation of the oil.
COOLING WATER PIPING
The cooling water piping epen s on what cooling coil or jackets
are furnishe an use . Jackets to be pipe in series are, Casing
Pe estal Cooling, Stuffing Box Cooling, an Bearing Housing
Cooling, with the cooling water to flow in that sequence. Not all of
these jackets will necessarily be use . All other jackets or cooling
coil shoul be pipe in parallel with separate flow to each. The cus-
tomer must provi e piping an a shut-off valve on each cooling inlet.
The customer must also provi e the outlet piping from each jacket or
cooling coil, fitte with a pressure relief valve set at a maximum of
150 PSIG, an then a flow control valve. Pipe each outlet from the
valve to it's own sight rain or through a suitable flow in icating
evice into the plant cooling water system.
In no case shoul the outlets be pipe into the municipal water
system.
COOLING WATER FLOW RATES
Stuffin box coolin , when use , has flow rates relate to pumping
temperature. See the chart below. The lower flow rates will lea to
higher cooling water temperature an promote more rapi scaling
within the jacket. Higher flow rates will o no harm.
Mechanical seal land coolin flow shoul be a juste to about 1/2
GPM.
Bearin housin coolin flow rate, when not in series with the stuff-
ing box cooling, shoul be a juste to 1/2 GPM. This will maintain
the oil temperature below 130°F at all pumping temperatures.
The pumps may be operate without bearing housing cooling if
experience with the particular installation shows that the bearing
temperature, without cooling, oes not rise above 200°F.
As state before, pumps operating at 500°F an lower, sel om
require bearing housing cooling.
Casin pedestal coolin flow rates are equal to stuffing box cooling
flow rates when pipe in series. If pipe separately, the flow nee
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 pe estal cooling is use to equalize an minimize thermal
expansion of the pe estal pump supports.

Lubrication of the ball type bearings in Dean pumps is by oil
containe in the sump of the bearing housing (26). The oil must
be a goo gra e of rust an oxi ation inhibite , non-foaming,
in ustrial 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
installe may a versely affect the oil level an re uce bearing
life. Proper care shoul be taken to avoi this con ition.
The R4000 series pumps are supplie with a “Bull’s Eye” type oil
level in icator, an fill openings on both si es of the bearing hous-
ing. Fill the sump through one of the NPT tappe openings on the
si e of the bearing housing until the oil level reaches the center of
the “Bull’s Eye” level in icator. The oil must be maintaine at this
level uring operation.
If the optional automatic oiler was supplie , it was packe separate-
ly for pump shipment to avoi amage. Install the oiler into the
upper 1” NPT tappe hole (connection #7 on page 7) on either si e
of the bearing housing. Screw the oiler reservoir from the top of the
“Bull”s Eye” housing, invert it, fill it with oil, an reinstall it into the
housing. Thereafter, the oil level in the bearing housing remains con-
stant as long as there is any oil in the reservoir cup. To maintain the
oil level between oil changes, refill the oil cup when the cup nears
empty.
The oil shoul be raine an replace at regular intervals, the inter-
vals epen ing on the atmospheric con itions ( ust, soot, corrosive
vapors, humi ity, temperature variations, etc.) prevailing at the
pump installation site. The bearing housing shoul be flushe with a
goo solvent before the oil is replace .
Pumps ar shipp d from th factory without oil in th b aring housing.
