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 (see
Figure 6
).
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. Replace the slinger on end of the motor shaft so that
the impeller sleeve will push it into position.
5. 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).
6. Apply a small amount of liquid detergent to the inside
diameter of the rotating seal member.
7. 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.
8. Screw the impeller onto the motor shaft clockwise. The
impeller will correctly seat the rotating seal member
on the seal plate.
For 2 HP, 2.5 HP and 3-Phase models, install the
impeller gasket and lockscrew (left-hand thread).
Torque the lock screw to 50-55 inch-lbs (57.6-63 kg/
cm).

9. Mount the diffuser onto the seal plate with the seven
(7) screws and washers. Torque screws to 10-14 inch/
lbs. (11.2-16.1 kg/cm).
10. Assemble the motor and seal plate to the pump body
with the seal plate to pump body hardware. Torque
nuts to 120-130 in-lbs. (138-150 kg/cm).
11. Reinstall the drain plug into the bottom of the pump
body.
12. Open all gate valves in the suction and discharge lines.
13. Reconnect power to the pump at the circuit breaker.
14. Prime the pump according to
Priming the Pump , on
page 4.
