Additional Description

Series 100 AB all bronze pumps are dependable, in-line booster pumps intended to pump potable, domestic water from hot water heater tanks to areas such as bathrooms and kitchens. The Series 100 features a three-piece design, which includes a motor, Bearing Assembly and volute. This innovative design provides for easy field service as the bearings, shaft and seal are all housed within the Bearing Assembly. That assembly can then be easily repaired or entirely replaced without disturbing the other components of your pump. The Series 100's resilient motor mounting is another feature unique to Bell & Gossett. The mounting, combined with spring-loaded couplers, means your pump will run quietly and efficiently. All Series 100 pumps have ODP, open drip-proof, motor enclosures. The Series 100 AB features a bronze impeller. A tube of Bell & Gossett oil along with flange gaskets and mounting hardware are included with the pump. Flanges are available separately in 3/4", 1", 1-1/4", and 1-1/2".

The industry standard circulator for decades, Series 100 is still the one by which most others are judged. With well over 10 million units installed, the Series 100 remains a leader in applications such as hydronic heating and domestic hot water circulation. Series 100's three-piece, oil lubricated design provides for easy field service with bearings, shaft and seal all housed in an assembly which can be easily repaired or replaced. The Series 100 oil lubricated motor is specifically designed for the Series 100, and its resilient mounting provides quiet, dependable service with minimum annual lubrication. UL and CSA listings are standard. The design of this motor, coupled with its overall hydraulic performance, allows the Series 100 to overcome system related noise caused by valves, fittings, or piping.
