Pump Insulation; Lubrication; General Instructions; Hex Guard Exploded View For Typical Installation - Bell and Gossett 1510 Series Instruction Manual

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.

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.

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.
