INSTALLATION
This manual provides installation, operation and mainte-
nance instructions for your Franklin Electric pump. The
manual will also make your personnel aware of any pro-
cedure that requires special attention because of potential
hazards to personnel or equipment. Read all instructions
carefully and remember this manual cannot anticipate or
warn of every situation that could occur. Because of this it
is the owners responsibility that only safe procedures be
used, if not addressed in this manual. If any question re-
garding the pump is not covered adequately please con-
tact you Franklin Electric representative.
This manual also provides a troubleshooting section to di-
agnose many operational or performance problems. The
equipment covered in this section is limited to the pump
only. Refer to the applicable vendor’s manual for motors,
engines and other accessory equipment. Use the trou-
bleshooting section to help determine the cause of any
problems, and only disassemble the pump components
required to remedy the existing condition.
FOUNDATION/BASE PLATE/SKID
If using a concrete foundation it should be rigid enough
to inhibit vibration. Pour the foundation well in advance
of installation of pump equipment to allow time for drying
and curing.
If the pump is to be mounted on a steel frame, or simi-
lar structure, it should be set directly over the support-
ing beams. These beams and the structure must be rigid
enough to prevent distortion and potential misalignment
due to movement within the structure or base. The loca-
tion of this structure should be as close as possible to the
pumpage source. Provide adequate space for operation,
maintenance and inspection of the pump and equipment.
The concrete foundation should be provided with anchor
bolts for attachment to the base plate. If required, pro-
vide adequate drainage to keep pump and motor dry and
clean. Also, provide either leveling nuts or leveling wedges
for mounting the base plate to the foundation.
LEVELING
When mounting the base plate to the foundation use the
leveling nuts or wedges to provide a level, flat base plate.
Use a machinist’s level on the mounting pads and make
adjustments as necessary as the anchor bolts are tight-
ened. This will provide the true alignment between the
pump and motor.
GROUT
If this base plate is to be grouted, ensure that you have
the mounting surface flat and level for correct alignment
of pump and motor. Build a dam around the base plate
perimeter that is to be watertight. Use standard grouting
practice and be sure to protect (cover) the leveling wedges
with caulk or plastic tape if they are to be removed later.
After the grout has thoroughly hardened, remove forms. If
the wedges are removed, fill holes with grout. Seal grout
by covering with a quality paint or sealer.
INSTALLING PUMP
Ensure that all foreign material has been removed from
the pump before mounting. Be sure to remove all shipping
protection prior to operation.
NOTE: Many of the bare pumps are shipped with protec-
tive guards and coatings.
SUCTION PIPING
For best performance the suction piping should be at least
as large as the pump flange, never smaller. Use an ec-
centric reducer at the suction flange with the straight side
up. The use of flow-retarding fittings is to be avoided and,
if necessary should never be placed closer than four (4)
times the pipe diameter to the pump suction. The pump
should be at the highest point of the piping. Slope the
piping up to the pump to prevent air pockets and avoid
changing pipe size with the exception of the eccentric re-
ducer mentioned above. All suction piping and fittings are
to be checked for any foreign material (rocks, bolts, wire,
etc.) and also any sharp burrs that could disrupt the flow.
DISCHARGE PIPING
Use a concentric taper on the discharge side to increase
discharge pipe diameters. All valving and additional fit-
tings should be the same size as the discharge main-line.
The discharge size should be adequate to maintain rea-
sonable velocities and reduce friction losses.
SUCTION & DISCHARGE PIPE FLANGES
All piping is to be supported, braced and lined up square
before connection to the pump flanges. A flexible fitting is
recommended on both suction and discharge, to eliminate
any piping strains being transmitted to the pump.
NOTE: Flexible pipe couplings must be restrained so as not
to transmit any strain to the pump flanges when expanding
or contracting under pressure. Unrestrained expansion fit-
tings can transmit enormous forces to the pump flanges.
SCREENING
Make provisions for the installation of a suction screen or
strainer to prevent any debris from clogging the impeller.
The open area of the strainer should be equal to at least
four (4) times the area of the pipe. The screen should be
rigid enough to prevent collapse when flow is reduced due
to clogging.
SUMP DESIGN
The submergence of the suction pipe into the liquid should
be at least four (4) to five (5) times the pipe diameter. If this
is not possible, then provide a baffle or a floating board to
prevent any vortex action allowing air into the pipe. For
best performance a bell mouth fitting is recommended.
Refer to the Hydraulic Institute Handbooks or other Hy-
draulic Data books for detailed sump design information.
LIFTING
Any lifting equipment is to be rated for at least five (5) times
the weight of the item being lifted. Use only established
methods when lifting or moving any heavy components.

non-volatile, non-flammable liquids containing speci-
fied entrained solids and corrosives. Do not attempt
to pump volatile, corrosive, or flammable liquids
which may damage the pump or endanger personnel
as a result of pump failure.
Pump speed and operating condition
points must be within the continuous performance
range for your specific pump model.
Any centrifugal pump must be primed before starting un-
less it is of a self-priming design. See preceding section
on priming and ensure suction pipe is filled with liquid.
With the discharge valve closed, start the pump and slow-
ly open the valve. Throttle the flow gradually to fully open.
Avoid any abrupt changes in the discharge flow rate to
prevent pressure surges in the piping. If the design pres-
sure is not achieved shut the pump down immediately.
Ensure that the pump is adequately primed and restart.
Never run the pump with the discharge valve closed for
extended periods of time. Never use the suction valve to
throttle the flow. Check all suction and discharge piping
for leaks.
If a suction strainer is installed, check the pressure drop
across the strainer. If the differential in pressure exceeds
five (5) PSI have the strainer cleaned.
OPERATION
PRE-START
1. Verify that rotation is correct and that the shaft rotates
freely.
2. Check all piping connections for tightness.
3. Inspect all accessories and make sure they are appro-
priate for your installation.
4. Verify that the driver and coupling are aligned correctly
and that all guards are in place.
5. Ensure that all bearings and grease seals are
lubricated.
6. Follow the instruction on all tags, labels and decals at-
tached to the equipment.
BEFORE STARTING
Make sure the pump is level.
Do not operate the pump without
guards in place over the rotating parts. Exposed
rotating parts can catch clothing, fingers or tools,
causing severe injury to personnel.

CAUTION
WARNING
CAUTION
Before any servicing:
1. Read this manual carefully.
2. Shut down driver and lock out incoming power to
ensure that the pump will remain inoperative.
3. If the pump or components are hot, allow adequate
cooling prior to servicing the unit.
4. Close the suction and discharge valves.
5. Vent the pump slowly and drain completely.
WARNING
MAINTENANCE
Before attempting to service this pump,
read this manual carefully. Operators and mainte-
nance personnel should have a good understanding
of all aspects of this pump and the pumping condi-
tions. Failure of operating personnel to be familiar
with all aspects of pump operation outlined in this
manual could contribute to equipment damage,
bodily injury or possible death.
WARNING
Use lifting and moving equipment in
good repair and with adequate capacity to prevent
injuries to personnel or damage to equipment. At-
tach lifting equipment to the lifting device fitted to
the pump. If chains or cable are wrapped around the
pump to lift it, make certain that they are positioned
so as not to damage the pump, and so that the load
will be balanced. Suction and discharge hoses and
piping must be removed from the pump before lifting.
WARNING
ALIGNMENT OF PUMP AND MOTOR
Precise alignment is mandatory to achieve correct perfor-
mance of the system. Every time a component is moved
this alignment will have to be checked. The alignment can
be checked with a straight edge and an outside caliper,
taper thickness gauge, dial indicators or, for best results,
use a laser alignment tool. Use the straight edge across
the outside diameters of the coupling to ensure that the
two halves are concentric and parallel. The outside cali-
pers or the taper thickness gauge is to correct for any an-
gular misalignment and to verify the correct gap between
the coupling flanges. Use a laser alignment tool or dial
indicators to adjust for concentric and angular displace-
ment. With dial indicators, rotate shafts together and take
readings every ninety (90) degrees. Make adjustments by
placing shims under the driver, and be sure that the mount-
ing bolts are properly tightened while taking readings, and
after final adjustment, then install coupling guard.
ROTATION
Before the pump is started, correct rotation must be con-
firmed. If the rotation is not correct then interchange any
two of the leads on a three (3) phase driver. For a single-
phase driver refer to the wiring diagram.
PRIMING
With a flooded suction use a bleed valve at the top of the
volute to allow trapped air to escape. If you are using a foot
valve, then fill the suction line and pump case with water
and use a bleed valve for trapped gas as above. Rotating
the pump shaft will release trapped gas in the impeller.

maintenance free, because of its rugged construction, for
extended periods of time. However, all centrifugal pumps
contain wear parts that will gradually deteriorate, which will
affect pump performance. This pump does contain wear
parts and these parts should be replaced as required to
maintain optimum performance.
General maintenance can be performed without removing
the pump from the driver. The instructions below assume
a complete disassembly of the pump is required.
SUCTION COVER AND WEAR RING (Figure 1)
If the pump is equipped with an external balance line it
must be removed prior to removing the suction cover. Dis-
connect the balance line from either the suction cover,
suction spool or the brackplate.
Support the suction cover using a suitable sling. Remove
the capscrews between the suction cover and volute.
Jackscrew holes are provided in the suction cover to aid
removal from the volute. Insert two of the capscrews at-
taching the suction cover to the volute into the jackscrew
holes, and tighten them evenly to jack the suction cover
free of the volute. If the suction wear ring shows grooves
or uneven wear it should be replaced. Minor irregularities
can be dressed with a fine file and crocus cloth. Wear rings
may be reworked by light machining, if proper equipment
is available to correct minor irregularities. After the removal
of any stock, the ring must remain within allowable clear-
ances for maximum performance. (Consult factory for
clearances for specific models).
When the pump performance drops below acceptable
Drain volute case of pumpage when pumping unit is idle to
avoid freezing and thermal cracking of pump case, etc.
Select a clean suitable location for any
required maintenance and note that all work must be
performed by qualified personnel.
An ongoing record of performance will assist in any trou-
bleshooting and/or analysis of problems. A pressure gauge
can be installed on the suction and discharge side of the
pump to monitor any changes in differential pressure. Dif-
ferential pressure is useful in monitoring and diagnosing
any possible degradation in pump performance.
DISASSEMBLY
Verify the following:
1. Driver is shut down and power is locked out.
2. If pump components are hot, allow to adequately cool.
3. Suction and discharge valves are shut.
4. Pump is drained.
Review all safety information and follow the instructions
in this manual, as well as, all tags, labels and decals at-
tached to the pump or related equipment.

CAUTION

ONE PIECE VOLUTE AND WEAR RING (Figure 2)
Support the volute using a suitable sling and remove the
capscrews between the volute and brackplate. There
are jackscrew holes in the brackplate flange to aid in re-
moval of the volute. Insert two of the volute capscrews
in the jackscrew holes, and tighten them evenly to push
the volute free of the backplate. If the suction wear ring
shows grooves or uneven wear it should be replaced. Mi-
nor irregularities can be dressed with a fine file and crocus
cloth. Wear rings may be reworked by light machining, if
proper equipment is available to correct minor irregulari-
ties. After the removal of any stock, the ring must remain
within allowable clearances for maximum performance.
When the pump performance drops below acceptable
limits, the volute wear ring should be replaced. This ring
can be removed by drilling two holes, of the proper size,

stalled tight against shoulder.
IMPELLER REMOVAL (Figure 3)
Remove the impeller lockscrew and washer at the cen-
ter of the impeller. Utilizing a properly sized gear puller,
evenly pry between the back shroud of the impeller and
the brackplate. Take care not to lose or damage the im-
peller key. As the impeller is being removed from the
shaft ensure that the seal spring, if present, is not lost
or damaged. Inspect the impeller and replace or repair if
warranted.
SEAL REMOVAL Rotating Element (Figure 4)
Once the impeller is removed, the rotating assembly of
the seal (bellows, spring and retainer) can slide off of the
shaft as a unit. Apply a light coat of oil to the shaft to help
free the rotating assembly. Take care to protect this as-
sembly from any foreign matter or damage.
BRACKPLATE REMOVAL (Figure 5 /Figure 6)
The “brackplate” can now be removed by removing the
capscrews between the brackplate and the bearing
housing. A sling or other support should be attached to the
brackplate prior to its removal. Slide the brackplate straight

off of the shaft to prevent any damage to the stationary
seal seat or the surface of the shaft. Care should also be
taken to avoid damaging the brackplate lipseal(s). The
stationary seal seat can now be pressed out of the brack-
plate bore, taking care not to break the seat. The entire
seal assembly can now be inspected for any damage that
will require replacement or reconditioning.
BEARING HOUSING (Figure 7)
If the frame bearings require servicing it will be necessary
to remove the bearing housing from the driver and the
pump end from the bearing housing. Remove the coupling
guard as necessary. With the bearing housing supported
with a hoist and sling remove bolts holding the housing to
the baseplate. Now the bearing housing can be moved
away from the driver for further servicing.
On the drive-end of the bearing housing remove the cap-
screws holding the bearing housing cover or the SAE
bracket to the housing. Gently slide the housing cover or
the SAE bracket off of the shaft to protect the lip seal if it
is to be reused.
Now the shaft assembly, including the shaft,bearings and
the bearing locknut and washer can be removed through
the drive-end of the bearing housing. This operation may
require placing a block of wood against the impeller end of
the shaft and tapping with a “dead blow” hammer or using
a mechanical or hydraulic press against the impeller end of
the shaft. If the bearings are to be re-used, the shaft should
be pressed out rather than tapped out with a hammer. With
the shaft and bearing assembly out of the housing the bear-
ings can be inspected and replaced as necessary.
Any work on the shaft and bearing as-
sembly should be done in a properly equipped shop
by experienced personnel. We recommend that the
bearings be replaced any time they are removed
from the bearing housing. Clean the bearing hous-
ing and the shaft and other components except the
bearings, with cleaning solvent and a string, lint-
free cloth. Inspect all parts and blow components
dry with compressed air. If the bearings are to be
replaced, the old bearings can be removed using a
suitable gear puller. It is recommended that brack-
plate and bearing cap lip seals also be replaced at
this time. These lip seals can be driven out of their
bores with a drift, punch or screw driver. Before
removing the lip seals note the orientation of the
lips, and be certain to install the new seals with the
same orientation. When driving or pressing in the lip
seals use a flat block or plate which applies pressure
around the entire circumference of the seal – do not
drive the seal in with a drift or punch.
When using cleaning solvent be sure to
have adequate ventilation, as most solvents are toxic
and flammable. Follow all precautions pertaining to
the solvent and keep area free from excessive heat,
sparks and flame.
Rotate the bearings by hand and check for any roughness
or wear. If any roughness, wear or discolored areas are
present, replace the bearings. Also, check the fit between
the bearings and shaft for a tight press fit and between the
bearings and the housing for a snug slip fit. If the fits are
not correct then replace the bearings, shaft or the bearing
housing as indicated by wear. If bearings are to be replaced
use a bearing puller to remove them from the shaft.
BEARING HOUSING REASSEMBLY (Figure 7 /Figure 8)
After all components have been inspected, repaired, and
or replaced ensure all parts are clean and ready for as-
sembly as indicated above. Use extreme caution, during
assembly, to protect all parts from dirt and damage. The
bearings should be installed using the bearing manufac-
turer’s recommended installation procedure.

If heat is used to install the bearing
use an induction heater, electric oven or hot plate.
Do not use a direct flame. Heat the bearings to a
uniform temperature of 220°F (105°C) maximum,
and slide each bearing onto the shaft until firmly
seated against the shaft shoulder. Once the bearing
is removed from the heat it must be placed over the
shaft and seated against the shoulder very quickly
or it will seize to the shaft in the wrong position.
After the bearings have cooled, ensure that they are
still seated against the shaft shoulder. If they are not
seated use a sleeve, of the correct size, and a press
to seat the bearing. This sleeve and press can be
used if heating the bearing is not practical, but only
press against the inner race of the bearing.
With the drive-end bearing firmly seated
against the shaft shoulder install the bearing lock-
washer and the bearing locknut. Refer to Figure 8
for the correct orientation. Ensure the washer tab on
the inside diameter is engaged in the slot in the shaft
and the tab pointed toward the bearing. After the
CAUTION
CAUTION

bearing nut has been tightened, bend one of the tabs
on the outside diameter of the washer to engage one
of the slots in the nut.
Some pumps are equipped with double angular contact
bearings at the drive end. It is imperative that these bear-
ings be installed in the correct orientation relative to one
another. When installing the first of the two angular con-
tact bearings onto the shaft make certain that the side of
the inner race with the largest diameter is located against
the shaft shoulder. The next bearing must be installed with
smaller diameter side of the inner race against the first
bearing. Refer to Figure 9.
Check that the bearing housing is clean and that the
bearing bores are free of any burrs or nicks. Ensure that
the bearing housing spacer (not used with double drive-
end bearings) is installed in the drive-end bore of the hous-
ing. Wait for bearing to cool, then, from the drive-end of
the bearing housing, slide the shaft/bearing assembly into
the drive-end of the housing. Press the drive end of the

REASSEMBLY
Slide the brackplate over the pump-end of the shaft, pro-
tecting the lip seals. Check that the brackplate drain port
is located in the bottom position. Secure the brackplate to
the bearing housing using capscrews provided.
If pump is grease lubricated both bearings should be ini-
tially packed with grease before reinstalling the bearing
cap and brackplate. A hand operated grease gun should
be used, after reassembly of the brackplate to the bearing
housing, to inject two or three “pumps” of grease between
these seals.
SEAL REASSEMBLY (Figure 4)
Always handle all seal parts with extreme care to prevent
damage. Be especially cautious not to contaminate the
precision finished mating faces as even fingerprints can
shorten seal life. If required, clean the faces with a non-oil
based solvent and a clean, lint-free cloth. Use a concentric
pattern while wiping to prevent scratching the faces.
Carefully inspect all seal parts for any damage or wear.
Any scoring or grooves in the mating faces could cause
the seal to leak, so it should be refurbished and mating
faces relapped or replaced with a new complete seal
assembly.
Clean the shaft and remove any nicks, cuts or burrs. Slide
the stationary seat over the shaft and carefully press
into the bore of the brackplate. Ensure that it is squarely
shaft until the drive-end bearing contacts the housing or
bearing spacer shoulder. Apply a light coat of oil or grease
to the bearing cap lipseal(s) that is installed or the SAE
bracket lip seal(s). Slide the bearing cap or SAE bracket
over the drive end of the shaft taking care to protect the
lip seal. Secure the bearing cap to the bearing housing
using the capscrews. Moving the shaft in both axial direc-
tions should produce a total endplay between 0.002” and
0.010”. Use bearing shims to limit endplay to this range.

LUBRICATION – BEARING FRAME
The lubrication of the ball bearings will depend on speed,
load, ambient temperature, contamination, moisture, in-
termittent or continuous service and other factors. These
regreasing recommendations are general in nature and
are to be used with good judgment and consideration of
the pump service. The following is a suggested lubrication
interval chart:
Frame Size 2,200 RPM 1,800 RPM 1,200 RPM
8.5 AK Frame 5,000 hrs. 7,500 hrs. 10,000 hrs.
12.5 AK Frame 2,500 hrs. 3,500 hrs. 5,000 hrs.
To lubricate the ball bearings, remove the plastic covers
from the zerk fittings. Ensure that the zerk fitting and the
end of the grease gun are clean. Use only a hand-oper-
ated grease gun with ball bearing grease as shown be-
low, or equal:
