1.- B&G Motor — The heart of the Booster. The finest circulator motor available. Sleeve bearing, oil lubricated with replaceable resilient motor mounts. B&G motors are designed and manufactured specifically for the B&G boosters.

2.- Noise dampening coupler. B&G’s own flexible spring design adds to quiet operation. Do not accept a substitute.

3.- Long bronze sleeve bearings maintain exact shaft alignment. Provides for constant circulation of oil over bearing surfaces.

4.- 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.

5.- The B&G mechanical seal isdesigned to withstand the wide range of water temperatures, pressures, additives and dissolved solids common in hydronic systems.

6.- Centrifugal impeller prevents accumulation of air at seal faces to assure long life. Close impeller/body tolerances minimize water slippage and maximize efficiency.
