Pump Reassembly / Installing New Seal

IMPORTANT: The ceramic seal of the pump's shaft seal
must be clean and free of dirt, grease and dust before
installing.
1. Wet the outer edge of the ceramic seal with a small
amount of liquid detergent. Firmly and squarely press it
into the seal plate cavity with your thumbs.
2. If ceramic seal does not seat properly into the seal
plate cavity, remove it and place the seal face up on a
flat surface. Reclean the seal plate cavity and attempt
to reseat the seal.
3. If ceramic seal still will not seat correctly in the seal
plate, place a cardboard washer over the ceramic seal
and use a piece of 3/4" standard pipe to press the seal
into place.
Note: Be sure not to scratch or mar the surface of the
seal. If seal is damaged it will leak.
4. Remount the seal slate onto the motor using the four
(4) motor to seal plate screws. Torque the screws to
60-80 inch-lbs. (69-92 kg/cm).
5. Apply a small amount of liquid detergent to the inside
diameter of the rotating seal member.
6. Slide the rotating seal member, polished carbon face
outwards, over the impeller sleeve until rubber drive
ring hits the back of the impeller.
Note: Be sure not to scratch or mar the polished seal
face. The seal will leak if damaged.
7. Screw the impeller onto the motor shaft clockwise. The
impeller will correctly seat the rotating seal member
into the seal plate.
For models including a center impeller screw, install
the impeller gasket and lockscrew (left-hand thread).
Torque the lock screw to 50-55 inch-lbs (57.6-63 kg/
cm).
8. Mount the diffuser onto the seal plate with the five (5)
screws and washers. Torque screws to 10-14 inch/lbs.
(11.2-16.1 kg/cm).
9. Assemble the motor and seal plate to the pump body
by reinstalling the band clamp.
Note: The clamp knob can be located in any position
around the volute. If it is moved after assembly, tighten
knob while tapping around clamp to assist sealing. DO
NOT move the clamp while the pump is full of water.
10. Reinstall the drain plug into the bottom of the pump
body.
11. Open all gate valves in the suction and discharge lines.
12. Reconnect power to the pump at the circuit breaker.
13. Prime the pump according to Priming the Pump, on
page 4.
