Bell & Gossett 102226 HD3 booster pump delivers 1/3 HP at 1725 RPM with 115/230V single-phase power. The cast iron construction handles hydronic heating and cooling systems with fluid temperatures up to 225°F. Includes flanges for easy installation.

Series HD3 cast iron pumps are dependable, in-line booster pumps intended to pump water through closed loop systems for heating and cooling. The Series HD3 is designed for applications that require increased flow and head pressures. The Series HD3 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 HD3'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. The Series HD3 features a plastic impeller. A tube of Bell & Gossett oil along with flange gaskets and mounting hardware are included with the pump. A pair of 3" flanges are also included.
