Periodic maintenance and inspection is required on all pumps to ensure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure to do so
voids warranty.
Centrifugal Laundry Tray Pump
Refer to pump manual 1808-634-00 for General Operating and Safety Instructions.
INSTALLATION
Refer to Figure 1 and proceed as follows:
1. Locate pump as close to the laundry tub as possible. Support the
pump and piping adequately to keep pump and piping from being
strained.
2. Pitch the piping from tub drain to pump suction to avoid air traps.
(Do not use the conventional trap). Keep the pipe-size at least
11/4”. Use pipe dope to avoid joint leakage. Install necessary
piping for pressure switches or any other control devices (not
supplied). Follow manufacturer’s instructions for their installation.
3. Install a check valve on the discharge side to prevent drain-back.
4. Locate check valve below level of bottom of tub.
5. Wire motor by following wiring diagram on nameplate. It is
strongly recommended that this unit is plugged into a GFCI
(Ground Fault Circuit Interrupter). Consult your local electrician
for installation and availability. Be sure unit is grounded (General
Safety Information). If unit is to be controlled by an on and off
switch, install at this time.
6. If laundry water from a washer is discharged into the laundry tub,
it should be ltered. Filtering can be accomplished many ways.
An easy way is by taking an old pair of panty hose, putting one
leg into the other, and then putting it on the end of the washer
discharge hose with a rubber band. Most of the panty hose
should be lying in the laundry tub. Eventually, the panty hose will
become full of lint and a hole will develop. The panty hose should
then be replaced.
7. Installation is now complete.
NOTE: To prevent accidents, locate motor in a suitable (ventilated)
enclosure, or guard all moving parts and ventilation openings.
OPERATION
Turn unit on by either plugging pump in, turning switch on, or if unit
is installed with an automatic device, (not supplied) it will activate
itself as well as turn itself off. On units without automatic devices, it is
necessary to shut pump off when water stops draining out of the tub
(last couple of inches). The pump has become air bound. After a few
seconds, when the water has gone down, turn unit on again. The unit
may have to be turned on and off a few times to completely drain tub.
This is normal. When water has been completely pumped out of the
tub, turn pump off immediately.
MAINTENANCE
Disconnect from power source before servicing or inspecting
the pump for any reason. Failure to do so could result in fatal
electrical shock!
MOTOR
Dirt accumulations can cause motor overheating and a re hazard.
Remove dirt accumulations from the motor, especially in and around
vent openings by vacuuming.
Periodically inspect the installation. Check for dirt accumulations;
unusual noises or vibration; overheating; worn or loose couplings,
sheaves and belts; high motor current; poor wiring or overheating
connections; loose mounting bolts or guards.
DESCRIPTION
This centrifugal laundry tray pump is designed for gravity-feed pumping operations. Unit can handle laundry water or other nonammable, non abrasive uids
compatible with pump construction. Pump is equipped with mechanical seal (carbon face with Buna-N seal cartridge), cast aluminum body and impeller, and
a split-phase motor. This is a manual unit, no controls are supplied. Unit does not come supplied with any type of switch or control device to turn unit on or off.

The motor used with this pump uses sleeve bearings which require
periodic reoiling. Each motor has two bearings, which should be
lubricated once a year. The bearings are located around the motor
shaft (See Figure 2), at each end of the motor. The oil reservoirs have
plastic plugs covering them. Pull out the plugs and put oil in. Replace
plugs after oiling.
Follow re-oiling instructions on the motor (see nameplate or terminal
box cover). If instructions are not included, re-oil once a year with 30-
35 drops of SAE No. 20 non-detergent or electric motor oil. Do not
over-lubricate.
PUMP
There is no normal pump maintenance. Some work might be required
on the pump when output has been reduced or when seal leaks. This
can be caused by lint build-up around the impeller. Disassemble pump
(See Mechanical Seal Replacement), remove impeller (Ref. No. 5)
and clean out, then re assemble.
MECHANICAL SEAL REPLACEMENT
After pump has been in service for a long period of time, or if pump
has been in severe service, it may be necessary to replace shaft seal
assembly (Ref. No. 3 & 4). Leakage can be detected by a dripping or
ow of liquid from area around motor shaft (Ref. No. 1).
The precision lapped faces on shaft seal assembly are easily damaged.
Handle your replacement seal carefully and read these instructions
before attempting to replace seal.
Refer to Figure 5 for Parts Illustration.
1. Disassemble casing (Ref. No. 8) and casing seal (Ref. No. 7) from
adapter (Ref. No. 2) by removing fasteners (Ref. No. 9).
2. Notice the location of impeller (Ref. No. 5) on shaft. It should be
compressing seal cartridge (Ref. No. 3). Loosen fastener (Ref.
No. 6) and impeller will slide off shaft.
3. Pry seal seat (Ref. No. 4) from impeller recess with a small
screwdriver (see Figure 3).
4. Press old seal cartridge out of adapter by pushing from motor
side.
NOTE: Use a 11/4” pipe or a socket from a tool set.
5. Clean adapter seal cavity before inserting new seal cartridge.
6. Carefully wipe polished surface of new seal seat with a clean
cloth.
7. Wet the rubber portion of seal seat with a light coating of soapy
water.
8. Press seal seat squarely into cavity in impeller as illustrated. If
seal seat does not press squarely into cavity, it can be adjusted
in place by pushing on it with a piece of pipe. Always use a piece
of cardboard between pipe and seal seat to avoid scratching seal
seat. This is a lapped surface and must be handled very carefully.
9. After seal seat is in place, check that it is clean and has not been
scratched or cracked.
10. Replace seal cartridge. A sealing compound (such as silicon or
Permatex) may be used to insure a water tight t on outside of
cartridge.
11. Mount adapter on motor mounting face.
12. Replace impeller, tightening it securely with fastener in
approximately same position it had been before disassembly.
(See Step 2).
13. Make sure casing seal is in place on adapter.
14. Replace casing, tightening securely with fasteners.
