Pump Reassembly

1. When installing the replacement seal into the seal
plate, use soapy water to wet the rubber boot
before pressing it into the seal plate.
2. Remount the seal plate to the motor.
3. Before installing the rotating portion of the seal on
the motor shaft, wet the motor shaft with soapy
water and slide the seal onto the motor shaft.
Ensure that the carbon face contacts the ceramic
face of the stationary seat. Press the seal into
the seal plate with your thumbs and wipe off the
ceramic with a clean cloth.
4. Screw impeller onto the motor shaft (clockwise to
tighten).
5. Screw in the impeller lock screw (counter-
clockwise to tighten).
Note: Insert a 1/4" hex Allen wrench into the
motor shaft through the hole in the rear motor
fan cover. This will prevent the motor shaft from
rotating and you screw in the impeller lock screw.
6. Remount the diffuser onto the seal plate. Make
sure the plastic pins and holding screw inserts
are aligned.
7. Grease the diffuser quad ring and seal plate
O-ring prior to reassembly.

pot-pump body. Tighten the bolts until all 4 bolts
are in place and finger tightened.
