MAINTENANCE
TYPE E WATER COOLED BALANCED DOUBLE SEAL
DISASSEMBLY, CLEANING (GENERAL)
It is necessary to disassemble parts of the pump for cleaning and sanitizing.
The extent of disassembly will depend on the application, and the type of seal used in your pump. To
disassemble, disconnect the suction and discharge piping. Remove seal guard assembly with wrench
of appropriate size. Turn the wing nut on the clamp assembly until tension on the clamp saddle is
relieved. Open the saddles and remove the casing. At this point the disassembly varies depending
on the impeller retaining system applicable to your pump.
For floating retainer models
Push back on the impeller and center the retainer in the stub shaft. Slide the impeller forward and
remove it.
For threaded shaft models
Remove cotter pin and turn castellated nut in counterclockwise direction, and remove washer and
impeller.
For both models
Disconnect the water inlet and outlet from the stuffing box. Remove the four screws that retain the
follower to the stuffing box. Slide the stuffing box and backplate assembly forward off of the stub
shaft. Remove the inboard carbon seal, seal o-ring, cup and the seal spring from the shaft. Loosen
the two set screws and remove the drive collar. The remaining carbon seal, seal o-ring, cup and the
follower may now be removed from the shaft.
WARNING
WARNING: Before servicing pump disconnect
electrical power source, carefully relieve all
pressure and drain all fluids from pump and
connected piping.
