Seal Replacement/Maintenance
Warning: Make certain that the system is disconnected from the power
source in compliance with all local and national codes before attempting
to service or remove any components. Never run the pump when dry.
Maintenance:
Inspection: Pump should be periodically checked for proper operation. If the system has changed
or if the pump is operating noisily or erratically, then the pump should be removed and examined.
It should be repaired and parts replaced as necessary.
Cleaning: Remove oil, dust, dirt, water, chemicals from exterior of pump and motor. Blow out
interior of open motors with clean compressed air at low pressure. Regularly drain moisture from
TEFC motors.
Draining: If the pump is located in an area subject to freezing temperatures, the pump must be
drained when not in operation or add sufficient antifreeze.
Seal Replacement:
Disassembly:
 Turn off the electric power and the water supply to the system.
 Drain the system. Flush if necessary.
 Remove the S.S. bolts (Ref 3) holding the housing (Ref 7) to the adaptor frame.
 Remove the two S.S. bolts mounting the assembly to the Mokon system base plate.
 Remove the cap screws, which hold the adaptor frame (Ref 1) to the motor.
 Loosen drive clamp assembly (Ref 5) and remove the pump.
The seal seat and seat cup will remain in the pump adaptor frame. If not damaged or worn, do not
remove. If necessary, remove the adaptor frame counter bore with a piece of wood or a
screwdriver handle inserted through the adaptor frame from the drive end. A sharp tap or two is
usually sufficient to knock out the seal seat. Use caution when removing the seal seat so as not to
damage the face or distort the metal seat.
