2. If ceramic seat will not locate properly, remove it,
place face up on bench and reclean cavity. Ceramic
seat should now locate.
3. If seat still will not locate properly, place a cardboard
washer over the polished face and use a piece of
3/4” (19mm) standard pipe for pressing purposes.
NOTICE Be sure not to scratch or mar polished
surface or seal will leak.
4. Replace slinger on end of motor shaft so that
impeller sleeve will push it into position. If slinger
shows signs of wear or damage, replace it.
5. Remount seal plate on motor. Tighten bolts to
60-80 inch-lbs. (69-92 kg/cm) torque.
6. Apply a small amount of liquid detergent to inside
diameter of rotating half of seal.
7. Slide rotating seal member, polished carbon face out,
over impeller sleeve until rubber drive ring hits back
of impeller.

Suction leaks/lost prime:
Pumpmustbeprimed;makesurethatpumpvoluteandtraparefullofwater.SeePriming Pump.
Make sure there are no leaks in suction piping.
Make sure suction pipe inlet is well below the water level to prevent pump from sucking air.
If suction trap gasket is defective, replace it.
Make sure pump is not trying to lift water more than 10’ (3m).
Make sure suction pipe is at least 1-1/2” (38mm) in diameter.

Make sure impeller is not clogged (follow instructions in Removing Old Seal;checkimpellerforclogging;follow
instructions in Installing New Seal for reassembly).
Impeller and diffuser may be worn. If so, order replacement parts. See Repair Parts.
Electrical:
Pump may be running too slowly
Check voltage at motor terminals and at meter while pump is running. If low, see wiring instructions or consult power
company. Check for loose connections.
Pump may be too hot.
Checklinevoltage;iflessthan90%ormorethan110%ofratedvoltageconsultalicensedelectrician.
Increase ventilation.
Reduce ambient temperature.
Tighten any loose connections.
Mechanical troubles and noise
If suction and discharge piping are not adequately supported, pump assembly will be strained. See Installation.
Do not mount pump on a wooden platform! Securely mount on concrete platform for quietest performance.
