PUMP SERVICE
Pump should only be serviced by qualified personnel.
To avoid dangerous or fatal electrical shock hazard, turn OFF power
to motor before working on pump or motor!
The Shaft Seal
The shaft seal consists primarily of two parts, a rotating member and a
ceramic seat.
CAUTION: The highly polished and lapped faces of the seal are easily
damaged. Read instructions and handle the seat with care.
Pump Disassembly/Removing Old Seal:
Disconnect power to pump motor.
Be sure gate valves on suction and return piping are closed before starting
work.
Release all pressure by opening all vents before starting work.
1. Drain pump by removing drain plug on bottom of pump body.
2. After unscrewing the impeller, carefully remove the rotating part of the
seal by prying up on the sealing washer, using two screwdrivers (Figure
5A). Use care not to scratch motor shaft.
3. Remove seal plate from motor and place on flat surface, face down.
Use a screwdriver to push ceramic seat out from seal cavity (Figure 5B).
Clean cavity from which seal was removed and clean motor shaft.
