SUBMERSIBLE PUMPS
b.
c.
Check any fuses and switches.
Check the cable, contactor and all connections.
Test for continuity. Also test the stator for turn fault
and insulation to ground.
d. Make sure that the impeller is clean and rotating
freely.
IMPORTANT: When trouble shooting; always follow local, state, and
federal regulations regarding procedures and safety. If the pump still
does not start, please contact the closest available recommended
repair shop.
2.
Low Capacity or Low Head: The cause can be clogged
passages, for example the strainer, a damaged or worn
impeller or pump housing, broken pipes, damaged or kinked
hoses or discharge pipe or too long or too narrow a hose.
3.
Water in the stator housing: If water is found in the stator
housing, the pump must be dismantled for a complete
overhaul and the stator dried out. Probable causes:
Damaged worn shaft seals or bad O-rings (Check oil
housing for water contamination). Change seals. Damaged
cable entrance (change).
4.
Water in the oil housing: Problem can be worn or damaged
oil lip seal and mechanical seals - change if needed; or
leaking inspection plug or oil house cover - change
elastomers.
START-UP DESCRIPTION: Check that the voltage of the power
supply is the same as that marked on the pump. When permanently
installing the pump, in a sump for example, make sure that the holding
capacity of the sump is commensurate with the capacity of the pump. If
the sump is too small, the pump will stop and start too often resulting in
damage to the pump. Recommended maximum start-ups per hour is 6.
If used with a hose, check that no kinks or restrictions are present.
ELECTRICAL CONNECTION: Check that the power is off and the line
is disconnected before working on any pump.
Always disconnect power before undertaking any work on a
pump, cable, control box or accessories.
HANDLING: Never lift a pump by its power cord. Always lift the pump
by its handle or attach a rope or wire cable to the handle or lifting rings.
Lifting by the power cord can cause dangerous electrical shorts or
pump failure.
PLACING THE PUMP: Never place the pump on a loose or soft
bottom. It could sink in and fill the pump housing with material, blocking
water flow to the impeller. Install the pump on a solid bottom or hang
the pump by a wire. If the pump is hung by a wire, it will have to be
restricted from twisting during start-up. This can be done by securing
the pump to one side of the sump. Stop and starts not to exceed 6
times per hour, make sure to size the pump according to sump size
and water inflow.
REPAIR AND MAINTENANCE INSTRUCTIONS
Follow the instructions on all tags, label and decals attached to the
pump:
Before attempting to open or service the pump:
1.
Familiarize yourself with this manual.
2.
Unplug the pump power cable to ensure that the pump will
remain inoperative.
3.
Allow the pump to completely cool if overheated.
4.
Do not attempt to lift the pump by the power cable or piping.
Attach proper lifting equipment to the handle on the pump.
a. Select a suitable location, preferably indoors, to
perform the degree of maintenance required.
LIQUID TEMPERATURE: The temperature of the water must not
exceed 120 degrees Fahrenheit.
SUBMERSION DEPTH: The maximum depth is 33 ft. (10m) or the
length of the factory installed electrical cable, whichever is less. If the
initial start depth in water is less than 3inches, the pump must be
primed.
COLD WEATHER: The pump will not freeze as long as it is
submerged and in operation. If it is removed from the liquid, empty the
pump, clean it and dry it. Then store it in a place where the
temperature is not below 32 degrees Fahrenheit (0 Celsius). If the
pump has been exposed to freezing temperatures, let it thaw slowly
before it is started again. Never thaw using flame or similar methods as
O-rings and other materials may be damaged.
If the motor housing is to be opened, the work must be done in a
clean, well-equipped shop. All maintenance functions must be done by
qualified personnel.
Obtain the services of a qualified electrician to service the
electrical components of this pump.
TROUBLES AND THEIR CURES
Complete disassembly procedures for the pump motor are not
included in this manual. Instructions are provided only for replacement
of pump end components, the pump power cable and capacitor. If the

hole in the pump top cover. Connect the ground wire and
stator leads to the power cable leads with the wire
connectors.
PUMP END DISASSEMBLY:
1.
To remove the strainer screen, lay the pump on its side,
disengage the hardware, and remove the strainer. If the
impeller is clogged, the debris can usually be removed
without further disassembly.
2.
Remove the machine screws and separate the suction cover
and suction cover O-ring. Immobilize the shaft by inserting a
large flat blade screwdriver into the slot in the end of the
shaft. Strike the impeller in a counterclockwise direction with
a soft-faced mallet or wood block and hammer until loose and
remove.
3.
SEAL REMOVAL: Remove the oil cavity drain screw and Oring and drain the oil from the seal cavity. Remove the
machine screws and use a pair of flat head screwdrivers to
pry the oil chamber cover and oil seal off the shaft as a unit.
Remove the oil chamber gasket. Invert the oil chamber cover
and remove the lower seal stationary element and seat from
the cover. With the oil chamber cover inverted, press the oil
seal out of the oil chamber cover from the back side.
Lubricate the seal area of the rotor shaft, and slide the
rotating portion of both the lower and upper seal assemblies
off the shaft.
To remove the stationary portion of the upper seal assembly,
slide two stiff wires with hooked ends along the shaft and
hook the stationary seat and element from the back side. Pull
the stationary portion of the seal from the bore of oil chamber.
Stuff a clean tissue into the stationary seal seat bore or wrap
a small rag around the shaft to prevent contamination of the
motor cavity. If no further disassembly is required, proceed
with the appropriate pump end reassembly procedures for
your specific pump.
4.
POWER CABLE REMOVAL: With the strainer and suction
cover removed, remove the discharge flange assembly.
Remove the handle. Remove the power cable clip from the
outer pump casing. Remove the hardware securing the cable
glad to the pump casing. Pull the outer pump casing up off
the motor, feeding the cable gland down through the hole in
the casing as the casing is removed. Remove the holding
rods and lock washers securing the motor top cover to the
stator casing. Raise the motor top cover to expose the power
cable leads and capacitor. Remove the connectors from the
power cable leads and remove the power cable and inner
power cable gland gasket. It is not necessary to remove the
ground wire unless replacement is required. To remove the
overload and the motor cover grommet, disengage the
machine screws. Use caution not to allow the motor leads for
the capacitor to slip down into the motor. If the capacitor
requires replacement, remove the shrink tubing (not shown)
and separate the capacitor leads from the stator leads.
5.
POWER CABLE INSTALLATION:
NOTE: Reuse of old O-rings or gaskets may result in premature
leakage or reduced pump performance. It is strongly recommended that
new O-rings and gaskets be used during reassembly (see the parts lists
for the O-ring/ gasket kit part number.
If the capacitor was removed, feed the motor leads for the
capacitor and overload through the new grommet and install
the grommet in the hole in the upper motor cover. Connect
the wires for the overload to those in the motor, and secure
the overload with the machine screws. Slide a piece of heat
shrink tube (not shown) over the capacitor leads. Connect the
leads on the capacitor to the capacitor leads from the motor.
Slide the heat shrink tubing down over the connections and
use a heat gun to shrink the tubing and seal the connections.
If the ground wire was removed, secure a new wire to the
motor top cover with the machine screw. Slide the gland end
of the power cable down through the outer pump casing.
Install a new outer power cable gland gasket against the
power cable gland. Push the power cable leads through a

CONNECTED TO THE GREEN LEAD GROUNDED TO THE MOTOR
TOP COVER FAILURE TO GROUND THE POWER CABLE OR
MISS WIRING OF THE GROUND LEAD COULD DAMAGE THE
PUMP AND/OR CAUSE SERIOUS INJURY OR DEATH TO
PERSONNEL.
Carefully fold the capacitor and power cable leads under the
pump top cover and secure the cover to the stator casing
with the holding rods and lock washers. Make sure the
cable leads are not pinched under the pump top cover.
Position the inner power cable gland gasket over the flange
on the motor top cover. Slide the outer pump casing down
over the motor and over the motor top cover flange. Secure
the pump casing to the motor top cover with one of the cap
screws and lock washers. Carefully compress the power
cable leads into the motor top cover and secure the power
cable gland to the cover with the machine screws. Install the
cable clip, flange assembly and handle.
6.
PUMP END ASSEMBLY: It is strongly recommended that
all seals and gaskets be replaced any time the pump is
disassembled. Thoroughly clean all reusable parts. Remove
all O-rings and gaskets, and clean the sealing surfaces of
dirt or gasket material. Be careful not to scratch gasket
surfaces. Inspect the rotor shaft for damaged threads,
scoring, or nicks.
Remove nicks and burrs with a fine file or emery cloth to
restore original contours. The shaft seal assembly should
not be reused because wear patterns on the finished faces
cannot be realigned during reassembly. This could result in
premature failure. If any components are worn, replace the
complete seal; never mix old and new seal parts. Handle a
new seal with extreme care to prevent damage. Be careful
not to contaminate the precision finished faces. Clean the
rotor shaft and seal cavity area. Be sure the area is dry and
free of lint and dirt. Check the seal bore for burrs or nicks
that might prevent a good seal. Apply a light coating of oil to
the bore.
When pressing seal components onto the shaft, use hand
pressure only. Ensure that the upper stationary element is
sub assembled into the stationary cup seat. Position this
subassembly Page 7 Document #27474 46-904 Rev. 03/03
in the oil chamber bore with the sealing face up, and cover
the seal face with a clean, lint-free cloth. Use your thumbs
to press the assembly into the bore. Apply equal pressure
on opposite sides until the seat contacts the bore shoulder.
Remove the tissue and inspect the seal face to ensure that
it is clean and dry. If cleaning is necessary, use a clean lintfree cloth to wipe lightly in a concentric pattern. Be certain
the seal face of the upper rotating element is free of grit or
surface damage and that it is clean and dry. Apply a light
coating of oil to the seal seating surface on the shaft and the
I.D. of the bellows. Apply a drop of oil to the seal face. Slide
the rotating portion of the upper seal assembly onto the
lubricated shaft. Apply firm, steady pressure on the seal
retainer until the seal slides onto the shaft and the upper
seal faces contact.
Repeat the above procedure for the rotating portion of the
lower seal assembly, making sure to position the lower seal
back-to-back against the upper seal. Position the oil
chamber cover with the motor side up. Ensure that the lower
seal stationary element is sub assembled in the stationary
cup seat. Position this subassembly in the cover bore with
the sealing face up, and cover the seal face with a clean,

lint-free cloth. Use your thumbs to press the assembly into
the bore. Apply a drop of oil to the lower seal stationary
face. Install the oil chamber cover gasket. Carefully position
the oil chamber cover over the shaft so the lower seal faces
contact. Install the machine screws and tighten them in an
alternating pattern until the seal springs are compressed
and the cover seats tightly against the gasket. Fill the seal
chamber with oil to cover the seals, but do not completely fill
the chamber. There must be enough air in the chamber to
allow for expansion as the oil heats. Refer to the
Lubrication Specifications at the end of this section for
the correct lubricant. Reinstall the oil cavity drain screw and
O-ring. Lubricate the lip of the oil seal and place the seal in
the oil chamber cover with the lip positioned as shown in the
seal detail, Figure 1. Press the seal into the oil chamber
cover until fully seated.
IMPELLER INSTALLATION: Lubricate the O.D. of the shaft

sleeve. Slide the sleeve over the shaft and through the lip
seal until fully seated against the shaft shoulder. Be careful
not to damage the lip seal. Screw the impeller onto the shaft
until it is fully seated. Insert a large flat-blade screwdriver
into the slot in the end of the shaft. Tighten the impeller on
the shaft by tapping it with a hammer and wood block or a
soft-faced mallet. Install the suction cover O-ring and
impeller housing/suction cover and position the strainer
screen against the impeller housing/suction cover, and
secure.
LUBRICATION SPECIFICATIONS: When shipped from the
factory, the pump seal cavity was fully lubricated with Shell
Turbo- T68 oil. Use only Shell Turbo-T68 or Gulf Harmony
HVI AW 26 oil for repair. Quantities for each pump are as
follows: Seal Cavity: Cover seal but do not completely fill
chamber.
