The pump is part of the total motor-pump system and utilizes one seal and ceramic to
prevent the pump from leaking around the impeller and shaft. One gasket is used to
prevent leakage between the pump and mounting plate and the machine pump plate.
REPLACEMENT OF SEAL AND/OR CERAMIC:
1. Remove power source to machine by turning circuit breaker to its "OFF" position.
2. Drain machine by removing over
fl
ow strainer in wash tank.
3. Support motor and remove the 4 nuts holding the pump/motor to the machine’s
pump plate.
4. Carefully pull motor outward and move from side-to-side as required to remove
from the machine.
5. Set motor and pump on a sturdy stand close to the machine or remove wires and
conduit to allow motor/pump to be moved to a better work position.
6. Remove the dust cap over the end of the motor shaft (opposite impeller end). This
can be done by wedging with a screwdriver.
7. Remove impeller. Hold shaft by inserting screwdriver in slotted end of shaft and
unscrew impeller in counter-clockwise direction.
8. The ceramic is embedded in the impeller and normally does not need replacement,
but it should be checked for cracks or a worn-out surface. If the ceramic does need
replacement, proceed as follows.
a. With a pointed,
fl
at tool, work the ceramic and rubber cap out of groove in
impeller.
b. Clean groove of all residue.
c. Apply a small amount of adhesive in groove.
d. Press new ceramic gently into groove with rubber cap leading the way.
NOTE:
The ceramic has one side with a groove in it. This side should be facing
down into the rubber cap. The smooth surface should be facing up.
9. The seal is embedded in the pump mounting plate and usually will need replacement
when water leaks around the motor shaft area. If replacement is required,
proceed as follows:
a. Remove the 4 bolts holding the pump mounting plate to the motor; must be
done with an allen wrench.
b. Slide mounting plate up off of the shaft and motor.
c. Press seal out of housing carefully.
