Bell & Gossett Three-Piece Circulators Feature The Finest Circulator Motor Available.
These three-piece circulators feature a sleeve bearing, oil lubricated motor that is built to last and provide optimum performance. Bell & Gossett Booster Pumps can be used for water circulating applications in hydronic, solar and chilled water systems. When equipped with a bronze pump body, Bell and Gossett booster pumps can be used with potable water systems. These three-piece circulators are designed to pump liquids at working pressures up to 125 psi at a maximum temperature of 225°F. Noise dampening couplers have a flexible spring design to promote quiet operation. Long bronze sleeve bearings maintain shaft alignment and provide constant oil circulation over bearing surfaces. These oil lubricated circulators feature an oversized precision ground pump shaft to support large bearing surfaces. Hardened integral thrust collar minimizes end-thrust to ensure long seal and bearing life. Internally flushed seal design prevents accumulation of air and dirt at seal faces to assure longer seal life. Close impeller/body tolerances help minimize water slippage to maximize efficiency.
