A - GENERAL INFORMATION
2. FOUNDATION
The pump foundation should be sufficiently substantial
to form a level, rigid support for the combined weight
of the pump and driver and maintain alignment of the
installed unit. Foundation bolts, of the proper size, should
be imbedded in the concrete. A pipe sleeve, about 2½”
diameters larger than the bolt, should be used to allow for
final positioning of the bolts. See Figure 1.
TO THE PURCHASER:
Congratulations! You are the owner of one of the finest
pumps on the market today. These pumps are products
engineered and manufactured of high quality components.
With years of pump building experience along with a
continuing quality assurance program combine to produce
a pump which will stand up to the toughest applications.
Check local codes and requirements before installation.
Servicing should be performed by knowledgeable pump
service contractors or authorized service stations.
RECEIVING:
Upon receiving the pump, it should be inspected for
damage or shortages. If damage has occurred, file a claim
immediately with the company that delivered the pump.
If the manual is removed from the crating, do not lose or
misplace.
STORAGE:
Short Term - Pumps are manufactured for efficient
performance following long inoperative periods in storage.
For best results, pumps can be retained in storage, as
factory assembled, in a dry atmosphere with constant
temperatures for up to six (6) months.
Long Term - Any length of time exceeding six (6) months,
but not more than twenty four (24) months. The units
should be stored in a temperature controlled area, a roofed
over walled enclosure that provides protection from the
elements (rain, snow, wind blown dust, etc..), and whose
temperature can be maintained between +40 deg. F and
+120 deg. F. Pump should be stored in its original shipping
container and before initial start up, rotate impeller by hand
to assure seal and impeller rotate freely.
Figure 1. Foundation Bolt Location and Anchorage
3. MOUNTING:
Pumps and drivers that are received from the factory
with both machines mounted on a common base plate,
were accurately aligned before shipment. All baseplates
are flexible to some extent and, therefore, must not be
relied upon to maintain the factory alignment. Preliminary
alignment is necessary after the complete unit has been
leveled on the foundation, and again, after the unit is
piped, and rechecked periodically as outlined in the
following paragraphs.
SERVICE CENTERS:
For the location of the nearest Deming Service Center,
check your Deming representative or Crane Pumps &
Systems Service Department in Piqua, Ohio, telephone
(937) 778-8947 or Crane Pumps & Systems Canada, Inc.,
Bramton, Ontario, (905) 457-6223.
Position unit on foundation and level the base plate,
using rectangular metal blocks and shims, or wedges
having a small taper. A gap of 3/4” to 1½” should be
allowed between the base plate and foundation for
grouting.
B - INSTALLATION
Adjust the metal supports or wedges until the shafts of
the pump and driver are level. Check the coupling faces,
as well as the suction and discharge flanges of the pump
for horizontal or vertical position by means of a level.
Correct the positions, if necessary, by adjusting the
supports or wedges under the base plate, as required.
1. LOCATION
The pump should be installed as near the source of liquid as
possible with a minimum of piping on the suction side of the
pump. The discharge piping should be as direct as possible
with a minimum of fittings to lower friction loss.
The unit should be installed with adequate head room and
a maximum area for inspection and service. The installation
should be dry, well ventilated, and protected against moisture
and flooding.

4. FLEXIBLE COUPLING ALIGNMENT
A flexible coupling should not be used to compensate for
misalignment of the pump and driver shafts. The purpose
of the flexible coupling is to compensate for temperature
changes and to permit end movement of the shafts without
interference with each other, while transmitting power from
the driver to the pump.
ANGULAR
MISALIGNMENT
CAUTION! - Remove and lock out power to
driver.
FACTORY ALIGNMENT
Pump and drivers that are received from the factory
with both machines mounted on a common baseplate,
were accurately aligned before shipment. All baseplates
are flexible to some extent and, therefore, must not be
relied upon to maintain the factory alignment. Preliminary
alignment is necessary after the complete unit has been
leveled on the foundation and again, after the unit is piped,
and rechecked periodically as outlined in the following
paragraphs.
FIELD ALIGNMENT
The faces of the coupling halves should be spaced far
enough apart so that they cannot strike each other when
the driver rotor is moved toward the pump. The necessary
tools for checking the alignment of a flexible coupling are a
straight edge and a taper gauge or a set of feeler gauges.
PARALLEL
MISALIGNMENT
NOTE: In most cases where extreme accuracy is
necessary, a dial indicator may be used to align coupling.
Angular alignment check is made by inserting a taper
gauge or feelers between the coupling faces at 90-degree
intervals around the coupling. The unit will be in angular
alignment when the coupling faces are exactly the same
distance apart at all points. (See Figure 2).
Parallel alignment check is made by placing a straight
edge across both coupling rims at the top, bottom and
at both sides. The unit will be in parallel alignment when
the straight edge rests evenly on the coupling rim at all
positions. Allowance may be necessary for temperature
changes and for coupling halves that are not of the same
outside diameter. Care must be taken to have the straight
edge parallel to the axis of the shafts. Correction for
Angular and Parallel Misalignment is made by adjusting
the shims under the driver. After each change, it is
necessary to recheck the alignment of the coupling halves,
as adjustment in one direction may disturb adjustments
already made in another direction.
PERFECT
ALIGMENT
The permissible amount of coupling misalignment will vary
with the type of pump and driver, but should be limited to
approximately .002 inches per inch of shaft diameter when
final adjustment is made. When the units are lined up cold,
it is necessary to make allowance for the vertical rise of
the driver caused by heating when in operation. When the
preliminary alignment has been completed the foundation,
bolts should be tightened evenly, but not too firmly.
Figure 2
5
There is always uneven flow in an elbow when it is
installed in any position other than a vertical position. This
unequal flow allows more water to enter one side of the
impeller than enters the other side causing a reduction
in capacity and efficiency. This condition may also cause
cavitation which would be characterized by noisy operation
and shorter pump life.
WARNING - Coupling guards must be used to
avoid serious injury to operating personnel.
5. GROUTING
Grouting compensates for unevenness in the foundation
and prevents vibration and shifting after mounting is
complete. Build a form around the base plate to contain
the grout, and sprinkle area with water to obtain a good
bond. The base should be completely filled with a good
quality, non-shrinking grout. The usual mixture for grouting
is one part Portland cement and two parts sand with
sufficient water to flow freely. It is also desirable to grout
the leveling pieces, shims or wedges in place. Foundation
bolts should be fully tightened when grout has hardened,
usually about 48 hours after pouring.
An eccentric rather than straight reducer and gate vale
with stem horizontal rather than vertical should be installed
in suction piping. (See Figure 3).
NOTE: A gate valve in the suction piping should not be
used as a throttling device, as this may cause the liquid to
overheat during operation.
DISCHARGE PIPING
A silent type check valve and a gate valve should be
installed in the discharge line. The check valve, placed
between the pump and the gate valve, is to protect the
pump against pressure surges and to prevent water
running back through the pump in case of failure of the
driver. The gate valve is used in priming, starting and when
shutting down the pump. This is especially important when
the pump is operated against a high static head.
if increasers are used on the discharge side increase the
size of discharge piping, they should be placed between
the check valve and pump.
6. PIPING
The pump suction and discharge connections are not
intended to indicate the required suction and discharge
pipe sizes. The pipe diameter must be selected according
to the requirements of the pumping system and
recommended friction losses for the liquid being pumped.
Usually, it is advisable to increase the size of both the
suction and discharge pipes at the pump nozzles to have
minimum acceptable friction loss, suction pipe should
never be smaller in diameter than the pump suction
nozzle. When suction pipe is of larger diameter than the
pump suction nozzle, an eccentric reducer is required to
eliminate possible air or vapor pockets at the pump suction
inlet.
7. WIRING
For electric motor drives, connect power supply to conform
with national and local codes. Line voltage and wire capacity
must match the ratings stamped on the motor nameplate.
Both suction and discharge pipes must be supported
independently near the pump, so that when piping is
connected to the pump, no strain will be transmitted to the
pump. Piping should be arranged with as few bends as
possible, and, preferably, with long radius elbow whenever
possible.
8. ROTATION
Before starting the pump, check the required direction
of rotation of the pump. The proper direction is indicated
by a direction arrow on the pump casing. Separate the
coupling halves, then start motor to see that it rotates in
the direction required by the pump. If it does not, reverse
any two main leads of the 3-phase wiring to the motor.
The coupling halves can be reconnected and the pump
primed for starting.
Where vibration noises must be kept to a minimum a
flexible connection is recommended on both the suction
and discharge lines. This will eliminate any sound being
telegraphed through the pipe system.
C - OPERATION
NOTE: Flexible connector should have limiting bolts to
contain hydraulic forces.
1. PRIMING
Install pet cocks on top of casing as shown.
SUCTION PIPING
A horizontal suction line must have a gradual rise to the
pump. Any high point in the suction pipe can become filled
with air and prevent proper operation of the pump and may
cause loss of prime. The pipe and fittings must be free of
all air leaks.
CAUTION: Before starting the pump, the casing and
suction line must be filled with liquid. The pump must not
be run until it is completely filled with liquid, because of
danger of injuring some of the parts of the pump which
depend upon liquid for lubrication. Wearing rings will not
seize when the pump is filled with liquid but are very liable
to do so when the pump is run dry.
Any valves or fittings should located at a distance equal
to 5 to 10 times the diameter of the suction pipe from the
pump suction nozzle. If an elbow must be installed at the
pump suction, it should be installed in a vertical position
to reduce unequal flow into the pump, which may cause
cavitation in the pump (See Figure 3).
Priming By Suction Pressure
When operating with suction pressure (flooded suction),
priming may be accomplished by bleeding all the air out of the
pump by opening the petcock located at the top of the upper
casing or at the top seal gland.
6
Figure 3
7
A pump operating under a suction lift may be primed by
any of the following methods, as may be best suited to the
conditions. The discharge valve should be closed during
priming operation.
The following important items should be checked as pump
is started and placed in operation.
a. Pump and driver securely bolted
b. Coupling properly aligned
c. Piping complete
d. Correct pump rotation
e. Pump shaft turns freely
f. Discharge valve closed
g. Suction valve open (if used)
h. Coupling Guard installed
i. Pump fully primed
j. Pump and driver properly lubricated
k. Seal water valve (if used) open
Priming by Ejector or Exhauster
This method is used when steam, high pressure water, or
compressed air is available.
1. Attach an air ejector to the highest point in the pump
casing. This will remove the air from the pump and
suction line.
2. As soon as the ejector waste pipe throws water
continuously, the pump may be started. After starting, a
steady stream of water from the waste pipe indicates
the pump is primed. If this stream of water is not
obtained, the pump must be stopped at once and the
process of priming repeated. A foot valve is unnecessary
when this kind of device is used.
Only after these items have been checked should the
pump be started.
3. INITIAL ADJUSTMENTS
Open discharge valve as soon as operating speed has
been reached. After the pump has been started the
packing box glands should be tightened to eliminate
excessive liquid loss. (Applies only to pumps having
packed stuffing boxes.) Packing should not be pressed
too tight, as this may result in burning the packing and
scoring the shaft or shaft sleeve. The best adjustment will
allow the liquid to drip slowly from the packing box gland.
This will permit proper lubrication of the shaft and dissipate
generated heat.
3. Open the discharge valve slowly and close off the
ejector.
Priming With Foot Valve
When it is not practicable to prime by ejector or exhauster,
the pump may be primed by the use of a foot valve. The foot
valve will prevent liquid running out through the suction inlet
and the pump can be completely filled with liquid from some
outside source. Pet cocks on the top of the pump should
be opened during filling to allow the air to escape. A tight
foot valve will keep the pump constantly primed so that the
pump may be used for automatic operation. The valve must
be inspected frequently, however, to see that it does not
develop leaks and thus allow the pump to be started dry.
As soon as the pump and driver have reached the normal
operating temperature, the unit should be shut down for
final coupling alignment. This should be done by following
the instructions found in Section B, Part 4.
Priming by Vacuum Pump
When neither of the above methods of priming are practical,
the pump may be primed by the use of a vacuum pump to
exhaust the air from the pump casing and suction line. A wet
vacuum pump is preferable, as it will not be injured if water
enters it. When a dry vacuum pump is used, the installation
must be such as to prevent liquid being taken into the air
pump. The vacuum pump manufacturer’s instructions
should be followed.
After the unit has been running for about one week,
the coupling halves should be given a final check for
misalignment caused by pipe strains or temperature
strains. If the alignment is correct, both pump and driver
may be dowelled to the baseplate if desired.
D. MAINTENANCE
2. STARTING THE PUMP
Position of Discharge Valve on Starting
A high or medium head centrifugal pump, when primed
and operated at full speed with the discharge gate valve
closed, requires much less power than when operated at
its rated capacity and head with the discharge gate valve
open. For this reason it is usually advantageous to have
the discharge gate valve closed when the pump is being
started. The pump must not be throttled by the use of a
valve in the suction line.
1. LUBRICATION
Grease Lubricated Pump
Pump bearings are properly lubricated with grease at the
factory before shipment. Periods of subsequent lubrication
depend on local conditions, loads, speeds, hours of
operation and temperature.
Periodic inspection of bearing lubrication should be made
and additional grease added as needed. At this time the
plug in the bottom of the bearing cover should be removed
and the bearing flushed with clean grease. A Chevron
SRI-2 or Shell Dolium “R” grease is recommended for
most installations. Do not overgrease as this causes high
bearing temperatures and shortens bearing life. The pump
should be run a short time to eject any excess grease and
the plug then replaced in the bearing cover.
WARNING! - Operating the pump with a closed
discharge valve can result in excessive heat
build-up and should be limited to the shortest
practical duration. Operating the pump at close
to shut-off head usually places greater bending strains
on the shaft than at operating points near the best
efficiency.
8
2. PACKING BOX
The packing glands should be adjusted occasionally to
insure proper packing lubrication. A slow dripping through
the gland is recommended for good lubrication and long
packing and shaft sleeve life.
14. Using overhead lifting device, hook onto rotating
assembly with nylon straps or rope, to not scratch
shaft. Remove bolts holding bearing housing to
pump casing. Remove rotating assembly from casing.
15. Mark impeller on coupling side , so if required to
remove from shaft, it will be reassembled correctly.
16. Remove coupling hub from pump shaft (may
require use of a gear or wheel puller). Remove
coupling key. (This is inboard side).
17. Remove three capscrews holding bearing cap and
bearing housing together. Remove bearing housing
(tap off using rubber hammer). Using a gear or wheel
puller, pull bearing off of shaft.
18. Remove bearing cap and water deflector (rubber
slinger) from shaft.
19. Loosen set screws in sleeve lock nuts, using a
spanner wrench. Remove (when used).
20. Remove seal cap. (Stationary seal seat is
pressed in).
21. Remove rotating seal assembly. (Packing and
packing bushing on pack pumps).
22. Slide shaft sleeve off
23. Remove both impellers and interstage diaphragm,
impeller key and casing rings.
24. Remove three capscrews holding bearing cap and
bearing housing together (outboard). Remove
bearing housing (Tap off using rubber housing).
25. Remove retaining ring (bearing snap ring).
26. Remove bearing (outboard) using gear or wheel puller.
27. Remove thrust collar. (Remove bearing cap before
thrust collar on verticals).
28. Repeat Steps 20 through 25.
When installing new rings of packing, clean packing box
and inspect parts for any damage. If the shaft sleeve is
worn or grooved, it should be replaced. New packing will
not do an adequate sealing job on a worn shaft sleeve.
Insert two new rings of packing in front of lantern ring.
Stagger joints to minimize leakage.
Tamp each ring in place. Replace lantern ring. Add two
rings of packing behind lantern ring. Replace gland and
bolts, rotate shaft and tighten gland securely. Loosen the
gland and add the final ring of packing. Be sure lantern
ring is positioned to receive lubrication through orifice.
Tighten nuts securely to seat packing and rotate shaft.
After rotating several turns, loosen nuts to finger tight for
starting.
3. DISASSEMBLY
The following procedure is for complete disassembly of
the pump. If complete disassembly is not necessary, use
only those steps which apply.
1. Shut off and lock put power to motor.
2. If hot liquids are being pumped, care should be
taken so personal injury is not incurred during
disassembly.
3. Totally depressurized pump and associated piping
by closing suction and discharge valves, to isolate
pump from system. Slowly open vent cock and then
remove drain plug from casing.
4. Remove all relief cooling, flush lines from pump.
5. Remove coupling guard
6. Loosen coupling set screws. Move coupling hubs
back and remove coupling sleeve.
7. Remove seal cap bolts by alternating the loosening
of the bolts. Exercise care to not cock the seal cap,
which could chip or crack the carbon seal face.
(Pack pumps remove packing gland).
8. Remove case rollpins. (Used to align upper and
lower halves).
9. Using some type of overhead lifting device, (a
frame, come a long chain fall, etc) hook onto the
two eyebolts or lifting lugs on top half of casing.
10. Remove bolts holding casing halves together. Turn
jackscrews in to separate the casing halves.
11. Set top half out of the way on a piece of cardboard
or wood, taking care not to scratch gasket surface.
12. Place casing gasket, as well as all other gaskets in
water to keep them from drying out and shrinking
13. Check seal setting (distance from machined surface
at the end of the stuffing box area to the seal collar).
This will need to be known to reset collar in the
proper position, if disassembly requires removal of
collar. (See Chart “Construction Details”).
4. REASSEMBLY
The following procedure is for the complete assembly of
the pump. This procedure must be followed for satisfactory
operation. If pump is not completely disassembled, use
only the steps that are applicable.
1. Install both impellers and interstage diaphragm,
with gasket between impellers. Make sure impeller
is installed on shaft the same way it came off, per
mark put on it during disassembly. (Double check
vane curvature as indicated as shown in Figure 4.
Figure 4
9
2. Install shaft sleeves. Be sure good hub gaskets are
in place on sleeves, to seal between sleeve and
impeller. If sleeves have internal o-rings, be sure
they are good. Make sure there are not sharp edges
or corners to cut o-rings. Line up slots on sleeves
with impeller key. If pack pump, install stuffing box
bushing. On mechanical seals, install stuffing box
bushing.
3. Clean and polish smooth the sleeves, making
sure there are no sharp edges or corners to cut the
seal’s rubber parts. If seal collars were removed or
being replaced, slide into place.
4. Inspect face of seal washer, if scratched or chipped,
replace. Clean inside of rubber bellows of seal
assembly. (Anti-freeze can be used as a lubrication
for installation of seal). Oil inside of seal bellows
and sleeves, with a mixture of 1/3 part STP and 2/3
part 10W oil. This allows seal assembly to be easily
pushed into position. Be sure the sealing washer is
in the proper position. The notches on the outside
edge of the sealing washer must mate with the lugs
in the retainer.
5. Slip spring retainer and spring over shaft or sleeve
and up against seal collar. Then slide the seal
bellows assembly over the sleeve, compressing
spring against seal collar, and seating spring
against bellows assembly. Gently release pressure.
The mechanical seal is a precision product, and
great care must be taken to avoid damage.
6. Inspect face of stationary seat. If grooved, replace
by removing old seal and cleaning seal cap. Oil
outer seal ring and push new seat into the seal cap
cavity, so the lapped surface side of seal seat will
mate with seal washer or rotating element taking
care not to marr seal surface. It must be seated
firmly and squarely.
7. Put casing rings on impeller
8. Put seal cap gaskets and seal caps into place.
9. Put 2 to 3 wraps of Teflon sealing tape on shaft
threads and start shaft sleeve locknuts when use.
10. Slide deflectors (rubber water slinger) onto shaft
11. Put on outboard bearing cap
12. Put on thrust collar.
13. Clean and check, or replace bearing. Hand pack
with a Lithium base grease
14. Put bearing on by only applying pressure to the
inner race. Care must be taken not to damage
seat, by wrapping a clean rag or paper towel around
shaft between seal cap and seal rotating element.
15. Install retaining ring (bearing snap ring), make sure
it is seated in grove shaft.
16. Clean all the old grease out of the bearing housing.
Check grease for saponification, which is usually
caused by infiltration of moisture, and noticed by the
whitish color of the grease. Also check for
carbonizing of grease which results from heat
caused by overgreasing. Put bearing housing on
and bolt up to bearing cap.
17. Put on inboard bearing cap.
18. Repeat Steps 13, 14 and 16.
19. Install pump coupling hub and key
20. If new casing half gaskets are to be installed, place
them onto lower half and trim to fix. CAUTION: Do
Not cut gasket at end of stuffing box in the seal
cap area.
21. Place rotating assembly into lower case, making
sure to fit holes in case wear rings on roll pins
in lower case half. (Keep seal cap gaskets next
to seal cap, to not tear them. Watch that seal collars
or packing bushings are in stuffing box).
22. Bolt outboard bearing housing to lower casing half
23. Bolt inboard bearing housing to lower casing half
24. Center impeller up in volute of lower casing half
25. Tighten shaft sleeve nuts and tighten setscrew in
sleeve nuts
26. If seal collars were removed or need resetting,
rotate them 30° before tightening set screws. Set
them using the dimensions from Step 15 or
Disassembly Instructions. NOTE: Seal collar face
(Surface next to seal spring) must be perpendicular
to the shaft while rotating shaft.
27. Pack pumps thread and tighten gland studs into
casing. Place one ring of packing into stuffing box.
On successive rings of packing, stagger the
packing joints 120° to prevent excessive leakage
through the packing box. Under suction lift
conditions, or when external flushing is required,
the pump should be fitted with lantern rings. Care
must be taken to locate these under the flushing
port drilled in casing. Each ring of packing should
be slid into place when being installed until stuffing
box is full.
28. Place casing half gaskets in place. When installing
new gaskets a small amount of grease evenly
applied to casing surface will help hold gasket in
place.
29. Put upper casing half (make sure seal caps and
seal cap gaskets will clear upper casing and that
jack screws in upper half have been backed off) into
place, taken care to install as to not slide gasket.
Check casing half gaskets at stuffing box and seal
cap area. Check for binding by rotating shaft.
30. Drive in case rollpins (to align upper and lower
halves) check for binding by rotating shaft.
31. Bolt casing halves together by tightening all bolts
until snug. To insure an equal clamping force,
tightening should be done in a sequence of steps.
First start with 50% of the full torque value, following
a “criss-cross” pattern. For instance, start at twelve
o’clock, then six o’clock, then nine o’clock, three,
o’clock, eleven, five, eight, two and so on. After the
initial tightening of 50% torque the bolts 70%, then
100% to achieve the required clamping force. Follow
the “criss-cross” pattern in each sequence. After
the initial tightening has been done, the bolts
should be retightened as often as necessary to make
up for the loss of clamping force that occurs as the
gaskets compress. With the torque calculated
properly, using the correct torquing sequence, the
seal against leakage will be assured. Check for
binding by rotating shaft. (Torque requirements).
10
FOOTNOTE: The rotating assembly can be adjusted by
loosening the three bolts that holds the bearing housing to
lower case half on one end or the other, or both. Lift up on
bearing housing and snug bottom bolt, then using a rubber
hammer, lightly tap housing while turning shaft. Repeat
until best position is found, then tighten all bolts.
32. Trim the casing half gaskets flush with casing at end
of stuffing box using a putty knife, file, etc.
33. Mechanical seal pumps: Remove rag or towel from
between seal cap and rotating element of seal that
was placed here in Step 15. Slide seal element into
place, check to be sure seal faces are clean, and
that the sealing washer is properly positioned in
retainer. Push seal cap and seal cap gasket in
evenly far enough to install seal cap bolts and washers.
Care must be taken to turn both bolts equally to
prevent cocking the seal cap and chipping or cracking
the carbon sealing washer. Check to make sure
gasket is in proper position. Note that these bolts only
need to be tight enough to compress gasket to seal.
34. Pack Pumps: Install the gland halves (Note: These
are in sets and marked as such and cannot be
mixed. The one with the hole goes on bottom), gland
washers and nuts. Tighten nuts down finger tight.
Be sure the gland has entered the box at least 1/8”.
If the packing will not compress to allow this, remove
one ring of packing. The breaking-in period of the
packing is more important in the satisfactory
performance of a stuffing box. When the pump
is returned to service, additional care must be given
the packing box to insure proper packing life. It is
necessary to allow 60 to 100 drops leakage per
minute through the packing for lubrication purposes.
If the flow rate is other than this, the gland nuts
should be loosened or tightened one flat (1/16 turn)
at a time to acquire the correct leakage (both nuts
must be turned equally to prevent cocking the gland)
allow at least ten minutes between adjustment for
the leakage rate to stabilize. When in doubt, choose
the greater leakage rate, since overly tightened
packing will ruin the packing as well as the sleeve.
35. Install relief cooling, abrasive separator, flush lines,
vent cock, drain plug and other fittings that were
removed during disassembly.
36. Open vent cock to evacuate air. Slowly open suction
valve, when air has evacuated close vent cock and
fully open suction valve. Open discharge valve
to its original position. Check for leaks and turn
rotating assembly. Never start a pump until all air
and vapor has been evacuated. Without fluid around
it, the mechanical seal may be ruined within a few
seconds of operation. It is possible that the
mechanical seals may drip the first few minutes to an
hour of operation.
39. Install coupling sleeve, adjust and align coupling.
Refer to alignment procedure section.
40. Install coupling guard
41. Turn power to pump on. Start and run pump
5. DOUBLE-WEAR RING IMPELLERS:
Remove - Wear rings are pressed and bolted on and must
be removed with puller or by drilling through the width of
the wear ring and removing with a chisel after the wear
ring locking screws are removed. Wear ring locking screws
can be removed by center punching and drilling out using
a 7/32” drill.
Install - Install wear rings onto impeller hubs. Drill through
each wear ring and impeller hub in two places 180° apart,
using a number 7 drill, tap holes with 1/4-20UNC tap
stopping 1 or 2 threads short of tapping through. Thread
screws into tapped holes until tight or flush with inside of
impeller hub. Cut screws off flush with outside diameter of
wear ring and file smooth any burrs or protrusions.
6. CHANGE ROTATION:
Follow disassembly instructions Steps 1 thru 24. Turn both
impellers and interstage diaphragm around and slide back
onto shaft. The mark put on impeller in Step 16 should
be opposite the coupling (driver) end of shaft. Follow
reassembly instruction Steps 1 thru 10, Steps 17 thru 39.
There is only one correct way for impeller to go in casing.
If pump is mounted on base, unbolt and turn casing
around 180°.
7. SEAL REPLACEMENT (Inboard):
Follow disassembly instructions Steps 1 thru 4, remove
flush line to seal cap only, 5, 6 remove three motor
mounting bolts and turn motor enough to allow for coupling
removal, 7, 16 thru 21.
Follow reassembly instructions Steps 5, 6, 7, 9, 10. 16, 17,
22, 28, 32, 34, 35, put motor back into place, 36 & 27.
8. SEAL REPLACEMENT (Outboard):
Follow disassembly instructions Steps 1, 2, 3, remove
flush line to seal cap, 7, 25 thru 28, then 18 thru 21.
Follow reassembly instructions Steps 5, 6, 7 thru 15, 21,
32, 34, 35.
9. SHAFT SEAL - TYPE 1 INSTALLATION
Remove top half of the casing. After determining size and
type of pump from name plate, find setting location of
seal collar, either X, Y, or Z, from Table 1. If the seal collar
needs resetting, rotate it 30° before tightening set screws.
