B&G Series 100 Pump Features
- Sleeve bearing, oil lubricated motor
- Its noise dampening spring coupler ensures quiet operation
- Precision ground oversized pump shaft provides long seal & bearing life
- Rugged mechanical seal that withstands wide temperature variation
B&G Motor - The heart of the Booster. The finest circulator motor available. Sleeve bearing, oil lubricated with replaceable motor mounts. B&G motors are designed and manufactured specifically for the B&G boosters.
Noise dampening coupler. B&G's own flexible spring design adds to the quiet operation. Do not accept a substitute.
Long bronze sleeve bearings maintain exact shaft alignment. Provides for constant circulation of oil over bearing surfaces.
Precision ground pump shaft is oversized to provide large bearing surfaces. Hardened integral thrust collar minimizes end-thrust to ensure long seal and bearing life.
The B&G mechanical seal is designed to withstand a wide range of water temperature pressures, additives and dissolved solids common in hydronic systems.
Centrifugal impeller prevents accumulation of air at seal faces to assure long life. Close impeller/body tolerances minimize water slippage and maximize efficiency.
