A Triple Duty Valve, such as the one manufactured by Bell &
Gossett, installed in the discharge line will serve as a check
valve to protect the pump from water hammer, as an isolation
valve for servicing and for throttling.
NOTES:
1. The pipeline should have isolation valves around the pump
and have a drain valve in the suction pipe.
2. When installing the suction and discharge connections to a
threaded pump housing the use of teflon tape sealer or a
high quality thread sealant is recommended.
LUBRICATION
While pump is running regrease pump bearing with NLGI
Grade #2 lithium base petroleum grease after every 2500
hours of operation or every 6 months whichever occurs first.
Lubricate motor per motor manufacturer’s instructions.
GENERAL INSTRUCTIONS
1. Keep this pump and motor properly lubricated.
2. When there is a danger of freezing, drain the pump.
3. Inspect pump regularly for leaky seals or gaskets and loose
or damaged components. Replace or repair as required.
PUMP INSULATION
When insulating a Series 1510 pump, ensure that the bearing
assembly grease fittings remain accessible and visible. The
vent slots on the sides and bottom of the bearing assembly
should remain uncovered and completely open.
