PACKING
1. The packing should be as loose as possible without an air leak, when the pump is
started. As the pump runs in, gradually tighten the gland bolts evenly. Recommend
adjusting the packing nuts no more than one flat every 25 minutes. There must be some
leakage. The leakage should be reduced to 40 – 60 drops per minute. Normally this will
take 50 – 60 minutes for packing to seal.
MECHANICAL SEALS
1. Check all fasteners to be sure they are tight.
2. Turn shaft by hand to ensure no binding exists.
3. Check seal, flush lines for leaks, if shut off valves exist, turn on.
PRIMING
A centrifugal pump should never be operated unless first filled with liquid and ALL of
the air vented out. The pump must NOT be operating to prime it.
1. Lock out power to the pump drive,
2. Remove coupling guard.
3. Slowly rotate the pump several turns by hand when priming. An operating pump
cannot be vented as the water will exit, but not the air.
4. Re-install the coupling guard.
5. Restore power to the pump.
The pump must be fully primed and suction pipe full of liquid before the pump is started.
CAUTION!
Do not operate the pump dry, rotating parts
may seize, damaging pump.
