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 .

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.
PUMP LUBRICATION
8

9
It is important that a pump shoul never be subjecte to thermal or
pressure shock. The liqui shoul therefore be allowe to flow into
the casing slowly. A centrifugal pump shoul never be starte until
all the parts are up to the temperature of the liqui to be pumpe .
If the pump is equippe with cooling water piping this shoul be
turne 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 liqui supplie to the pump is below atmos-
pheric pressure or locate below the pump, the pump must be
prime prior to start up. The priming may be ac complishe in any
of several ways, three of which are liste .
1) An exhauster may be connecte to the ischarge piping
between the pump an the ischarge shut-off valve. With the
ischarge shut-off valve close an the suction valve open, the
air can be exhauste from the pump an piping.
2) With a foot valve installe in the suction piping, the pump may
be fille with liqui intro uce somewhere above the pump in
the ischarge line. The seal chamber shoul be vente to
allow complete filling. A foot valve may create extensive losses
an shoul be taken into consi eration in calculating the avail-
able NPSH.
3) A vacuum pump (preferably a wet vacuum pump) may be
use for evacuating air from the pump an piping. The
vacuum pump shoul be connecte as is the exhauster
covere in No. 1.
When the source of liqui supplie to the pump is above atmospher-
ic pressure or above the pump centerline, the pump may be fille by
venting through a blee 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
shippe with the coupling spacer not installe to allow alignment
an motor rotation irection check. If, however, someone installe
this spacer assembly, lock-out the power to the river (motor, turbine,
engine, etc.), an remove the spacer assembly at this time. If the
pump was purchase with the “C” face motor support option, the
coupling will not have a spacer assembly. To check rotation irec-
tion, push the starting button an instantly push the stop button. This
will allow the motor to turn over a few revolutions an the irection
of rotation to be observe . A irection of rotation arrow is shown on
the front of the pump casing. If rotation is incorrect, change the
wiring connections an 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 (except for pumps with the optional
“C” face motor support). 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 started. Bolt the cou-
plin uard securely into place, checkin to assure that it is not con-
tactin 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 shoul be starte with the suction valve open
an the ischarge valve opene a slight amount.
As soon as the pump is up to spee , the ischarge valve must be
opene slowly. A centrifugal pump cannot be operate with the
ischarge valve close without heating up angerously. During the
first several minutes of operating watch the pump carefully for
overheating, vibration, an other abnormal con itions. If trouble
evelops, stop pump at once an correct the problem.
STARTING THE PUMP

10
PUMP START UP CHECK LIST
To avoi prolonge own time an facilitate rapi repair of am-
age pump parts, Dean recommen s 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 exten from a
spare mechanical seal or seal parts through complete casing back-
cover-impeller-bear ing housing assemblies prepare for imme iate
insertion in the pump casing. Consult your Dean representative who
will assist you in selecting your spares stock.
ORDERING SPARE PARTS
Spare part or ers will be han le with a minimum elay if
the following information is furnishe by the customer with the
or er:
1) Give the pump serial number an size. These may be
foun on the pump name plate. The serial number is also
stampe on the suction flange or the top e ge of the bear-
ing housing front flange.
2) Give the part name, part number, an material of part.
These shoul agree with the stan ar parts list.
3) Give the quantity of each part require .
4) Give complete shipping instructions.
SPARE PARTS
These points must be checked after pump installation and before
startin up the pump.
1) Rea instruction manual thoroughly an un erstan it.
2) Review pump or er hea sheet for the service rating of the
pump an any special features.
3) Check all piping connections making certain that they are both
tight an in the proper places. All piping inclu es seal, cooling,
or heating piping.
4) Make sure that the baseplate has been properly installe .
5) Check the electrical or steam line connections to the river.
6) Break the coupling by removing the coupling spacer (except for
pumps with the optional “C” face motor support) an bump the
motor starting button to check motor rotation. Operating the
pump in reverse rotation may cause extensive amage. If river
rotation is correct, replace the coupling spacer. If not, connect
the wiring for proper rotation an recheck.
7) Check coupling for proper alignment (except for pumps with
the optional “C” face motor support). Realign if neces sary.
8) If pump seal chamber is packe , check to be sure that
glan stu nuts are pulle up only finger tight an that the
glan is not cocke .
9) Rotate the pump shaft by han to be sure there is no
bin ing or rubbing within the pump or river. Correct any
ifficulties at once.
10) Check to see that the pump is properly lubricate .
11) Remove all irt, waste, tools, an construction ebris from
the area.
12) Check to see that the coupling guar 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 river (motor, turbine, engine, etc.) an lock
the switching evice so that it can not be restarte . Tag the
switching evice so that no one will attempt to restart the unit.
b) Close the suction an ischarge valves completely to isolate the
pump from the system. Lock the valves in the close position
an tag them so that no one will attempt to open them.
c) Turn off, lock out, an tag all sub-systems an auxiliary equip-
ment an auxiliary supply lines to isolate the pumping unit from
any an all power, energy, an /or flui s.
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.
) Remove the coupling, guar (s).
e) If the pump an river are in epen ently mounte to a com-
mon baseplate (not connecte 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 an river (motor or turbine) are connecte togeth-
er by a “C” face motor support (83), isconnect the power
supply from the river. Place woo block an we ges, un er
the rear feet of motor sizes 143TC through 215TC, or un er
the motor support (83) of motors sizes 254TC through 365TC.
These blocks are to be positione so as to support the weight of
the motor an the motor support (83) when they are separate
from the pump. Hook a lifting hoist to the lifting eye(s) of the
motor an 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
an motor support (83) as you are removing these bolts.
Carefully move the motor an motor support (83) assembly hor-
izontally an axially away from the pump, gui ing 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 flui s from all the auxiliary sub-systems (lubrication,
cooling, heating, seal barrier, etc.) that are connecte to the
pump. Drain each flui into a separate container. Use caution
require for each flui after rea ing the MSDS (Material Safety
Data Sheet) for each.
k) Flush each sub-system with a compatible, non-toxic, non-haz-
ar ous, stable liqui . Drain into in ivi ual containers for each
flui . Disconnect an remove all auxiliary piping.
l) Carefully blee off any pressure remaining in the pump.
Pressure remaining in the pump will be epen ent upon the
pressure in the system when the pump was stoppe ; the quality,
type, an con ition of the isolation valves; the thermal expan-
sion values of the flui an the pump material; an the change
in the vapor pressure of the flui between the temperature at the
time the isolation valves were close an the ambient tempera-
ture. Blee ing must be through a valve rain line pipe to a
close container mounte lower than the pump. The container
must be arrange with a relief passage to some point where
pressure an fumes will not be harmful to personnel. The con-
tainer must also have a level evice so that etermination can
be ma e that sufficient flui has been raine to empty the
pump cavity an the volume of flui that was containe in the
run of suction an ischarge pipe between the isolation valves
an the pump. After the initial rush of flui from the pump
relieves the pressure, the rain valve can be opene further to
spee the raining operation. When flui quits running into the
rain tank, gage the volume to see if it is sufficient to have fully
raine the contents of the pump an the suction an is-
charge pipes between the isolation valves.
If the system was constructe without any rain connections, it
will be necessary to consult the esigners of the system for safe
raining proce ures.
m) Now rain any small piping, that contains the flui pumpe ,
from all low points into the same container use to rain the
pump. Do not rain any other flui s ( ifferent then the
pumpage) into this container as they may not be compatible.
Personal injury, eath, an /or equipment amage coul 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

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 gaskete
joint at the back of the casing (5), loosen the casing nuts (5C)
only one full turn, an then use the jack screws in the flange of
the cra le spacer (7) to break the gasket seal. If flui an /or
pressure remains in the pump it will spray out now. Use
extreme caution, wearing protective gear, to avoi injury. Do
not procee with isassembly until leakage ceases completely.
If leakage oes not cease, the isolation valves may not be seal-
ing. Note that if the pump was purchase without a rain, the
pump will contain flui which will flow out at the time the nuts
are loosene an 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) an using a mechanical lifting
apparatus to support the weight, pull the rotating unit from the
casing (5).
p) Flush the wette parts, now expose , with a compatible, non-
toxic, non-hazar ous, stable liqui .
q) Remove the gasket from the face of the casing (5) or the casing
back cover (22) epen ent on which one the gasket may have
a here to. The type of gasket an material of construction will
vary with service requirements. Attack by prying an then, if
necessary, layering off the ol 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 an uring the
scraping operation to re uce the possibility of fibers becoming
airborne. Wear a respirator uring this operation an until all
ebris has been ispose of in a plastic bag. Remove all of the
gasket material own to clean metal surfaces on both parts that
contacte the gasket. Place all of the gasket resi ue in a plastic
bag, seal the bag an ispose.
r) The rotating assembly of the pump can now be move to a
more convenient location for further isassembly. Use mechani-
cal lifting equipment to move assemblies an components.
DISASSEMBLY PROCEDURE
To further ismantle the pump, perform the following steps in the
sequence shown:

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 parts.
To reassemble the pump, perform the following steps:
a) Clean all parts thoroughly.
b)
If nee e , press a new throat bushing (54) carefully into the casing
backcover (22).
c) If nee e , press a new casing backcover ring (6) into the casing
backcover (22).
) If nee e , press a new casing ring (6A) into the casing (5).
e) If the bearing housing foot (9) was remove , bolt it back to the
bearing housing (26). Be sure that the owel pins are in place
between the foot (9) an the housing (26). Tighten the cap-
screws to 50 ft. lb for series R4140 an R4170 pumps. Tighten
the capscrews to 80 ft. lb. for series R4180 an R4240 pumps.
f) If the bull’s eye sight glass was remove , apply pipe sealant to
the threa s of a new bull’s eye sight glass an tighten it into the
si e of the bearing housing (26). Torque to 50 ft. lb.
g) If the bearing housing vent (80) was remove , install a new
vent (80), without threa sealant, into the top of the bearing
housing (26). Tighten to 20 ft. lb.
h) Install new “O” rings onto the O.D. an into the I.D. of both the
labyrinth seals (76 an 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 en cover
(28). The “expulsion port” (the slot in the O.D.) of the labyrinth
(76A) must be positione at the bottom of the en cover. This
will be inline with the machine “oil return” slot in the en
cover (28).
k) Press the bearings (25 an 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 matche pair of angular
contact bearings an must be assemble “back to back”. See
the illustration on page 18. If the pump is of series R4140,
R4170, or R4180, 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
(31A), while hol ing the shaft (29) against rotation with a hook
spanner in the keyway at the coupling en of the shaft. Another
way to keep the shaft from turning is to place the coupling hub
an key onto the shaft an hol the hub with a wrench. Tighten
the nut to the torque value below:
75 ft. lb. on the R4140 series
90 ft. lb. on the R4170 series
100 ft. lb. on the R4180 series
130 ft. lb. on the R4240 series
Ben one of the tabs of the lockwasher (31A) into the corre-
spon ing slot in the locknut (31).
m) Lubricate the O.D. of the bearings (25 an 25A) an the bores
of the bearing housing (26). Sli e the shaft (29) bearing (25
an 25A) assembly into the rear of the bearing housing (26). If
the pump is of the R4140, R4170,or R4180 series, after the
ra ial bearing (25) has passe through the rear bore of the
housing, reach into the opening, with snap ring pliers, an
place the retaining ring (75B) into the rear bore of the housing.
Install the retaining ring with the opening in the ring at the bot-
tom of the housing so that it is centere with the oil return
groove in the housing. The ring oes not have to be in it’s
groove as the bearing housing is machine with a long cham-
fer that allows the thrust bearing (25A) to push the ring into its
groove as the shaft assembly is pushe into the bearing hous-
ing. The shaft assembly may now be fully inserte until the thrust
bearing (25A) is firmly against the retaining ring (75B), an the
retaining ring is firmly in its groove.
If the pump is of the R4240 series, fully insert the shaft assembly
into the bearing housing until the thrust bearing (25A) is firmly
against the shoul er in the rear bore of the bearing housing.
n) Lubricate the en cover gasket (77B), which is an
“O” ring.
Place the en cover gasket (77B) onto the en cover (28).
Lubricate the I.D. of the rear labyrinth seal (76A), which is in the
en cover (28). Lubricate the area of the pump shaft (29), just
behin the thrust bearing (25A), where the rear labyrinth seal
(76A) will be mounte . Sli e the bearing en cover (28), labyrinth
seal (76A) assembly carefully over the en of the pump shaft (29).
Be careful that the “O” ring in the I.D. of the labyrinth seal (76A)
oes not contact the keyway of the shaft (29) an become am-
17

age . Placing a piece of plastic electrical tape over the keyway,
before this assembly operation, will give a measure of protection.
Rotate the en cover (28) so that the machine “oil return slot” is
towar s the bottom of the bearing housing (26). Seat the en
cover fully into the bearing housing an tighten the en cover bolts
to 20 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 an carefully gui e the en of the tubing through the tub-
ing connector on the opposite si e of the bearing housing (26).
Apply pipe sealant to the 1” male pipe threa s, an tighten the 1”
tube connector into the bearing housing (26) with a torque of 50
ft. lb. The ferrules use in these tube connectors are plastic, to
enable isassembly an re-assembly without amaging 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 ra ial bearing (25), where the front labyrinth seal (76)
will be mounte . Sli e the seal ring (27), labyrinth seal (76) assem-
bly carefully over the en of the pump shaft (29). Be careful that
the “O” ring in the I.D. of the labyrinth seal (76) oes not contact
the keyways of the shaft (29) an become amage . 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 positione so that it is towar s the bot-
tom of the bearing housing (26)
q) Dean pumps are ma e with a lappe metal-to-metal joint between
the shaft sleeve (10) hook an the locating shoul er on the shaft
(29) to prevent liqui leakage un er the shaft sleeve. The following
instructions shoul be carefully observe when the shaft is reassem-
ble to the shaft:
1. Apply a small amount of 280 grit lapping compoun (simi-
lar to automobile valve grin ing compoun ) to the insi e
shoul er of the shaft sleeve hook.
2. Sli e the shaft sleeve (10) onto the shaft. Do not install the
shaft sleeve key (10K).
3. Rotate the shaft sleeve repeate ly by han in its place on
the shaft until the markings on both shaft an sleeve hook
show that complete metal-to-metal contact has been ma e.
4. Remove the shaft sleeve an flush all lapping compoun
from the sleeve an shaft. Reassemble the shaft sleeve on
the shaft with the shaft sleeve key (10K) in place.
r) Assemble the cra le spacer (7) to the bearing housing (26).
Tighten bolts to 50 ft. lb.
s) If the pump stuffing box is to be packe , sli e the packing
glan (13) over the shaft sleeve an back against the front
labyrinth seal (76).
t) If the pump is equippe with a mechanical seal, assemble the
seal parts on the shaft sleeve at this time. See separate mechan-
ical seal installation instructions.
u) Sli e the casing back cover (22) carefully into place an secure
it to the cra le spacer with the two capscrews. Be especially
careful not to amage mechanical seal parts. Tighten bolts to
30 ft. lb.
v) Place the impeller key (4) into the shaft (29) keyway an sli e
the impeller (3) into position on the shaft (29).
If the pump is of series R4140, R4180,or R4240, rive the
impeller lockwasher owel (12C) into the impeller washer
(12A) until it is flush with the si e of the washer that has a blin
hole. Place the impeller bolt (12) through the impeller lock
washer (12B) an then the impeller washer (12A) so that the
protru ing part of the impeller lock washer owel (12C) is
away from the hea of the impeller bolt (12). Screw the
impeller bolt (12) into the shaft (29) while gui ing the protru -
ing impeller lock washer owel (12C) into the keyways of the
impeller (3) an the shaft (29).
Tighten the impeller bolt (12) to the torque value below:
60 ft. lb. on the R4140 series
100 ft. lb. on the R4180 series
150 ft. lb. on the R4240 series
Use a rive pin punch to ben the e ge of the impeller lock
washer (12B) into the blin hole in the impeller washer (12A).
Use a chisel to ben the si e of the impeller lock washer (12B)
up against a flat of the impeller bolt (12) approximately 90°
from the blin hole.
If the pump is of series R4170, rive the impeller lockwasher
owel (12C) into the impeller washer (12A) until it is flush with
one si e of the washer. Place the impeller washer (12A) over
the threa e en of the shaft (29), gui ing the protru ing
impeller lock washer owel (12C) into the keyways of the
impeller (3) an the shaft (29). Place the impeller lock washer
(12B) over the threa e en of the pump shaft (29). Screw the
impeller nut (left han threa ) onto the en of the pump shaft
(29) an tighten it to 120 ft. lb. Use a rive pin punch to ben
the e ge of the impeller lock washer (12B) over the flat on the
si e of the impeller washer (12A). Use a chisel to ben the si e
of the impeller lock washer (12B) up against a flat of the
impeller nut (12), approximately 90° from the flat on the si e of
the impeller washer (12A).
w) Replace the coupling key into the keyway at the coupling en
of the pump shaft (29).
x) If the pump an river are in epen ently mounte to a com-
mon baseplate, place the pump coupling hub (inclu ing the
four axial bolts) onto the pump shaft (29), flush with the en of
the pump shaft, an tighten the set screws. Go to step z).
y) If the pump an river are connecte by a “C” face motor
support, place the pump coupling hub onto the pump shaft
(29), to the location note below, an tighten the set screws.
