Circulating Water Pump Motor (Part No. 12A4020G01- 60hz, 12A4020G08 – 50hz)
The motor bearings are prelubricated and sealed. They require no further lubrication. The pump
should operate with the water level above the impeller housing. The pump is equipped with a
mechanical seal that is self-adjusting and requires no lubrication. However, the pump should not be
operated unless circulating water. The pump manufacturer recommends that a mechanical seal be kept
as a spare. When ordering a seal, specify pump size, type, serial number, and manufacturer’s name as
indicated on the nameplate.
