Special motors available upon request. Dimensions are approximate and subject to changes.
Contact factory for certified dimension.
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 is
designed 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.
