Bell & Gossett Series 2-1/2 Three-Piece Booster Pumps

Bell & Gossett Series 2-1/2 three-piece booster pumps circulate fluids within hydronic heating and cooling systems. These pumps consist of three distinct components: a motor, a coupler, and a pump assembly. The motor drives the impeller, which moves water through the piping network. The coupler connects the motor shaft to the pump shaft, allowing torque transmission. These units operate in closed-loop systems to maintain fluid flow and pressure. The three-piece design allows for the replacement of individual components without removing the entire pump housing from the piping. This configuration supports maintenance and repair procedures. These pumps function with various motor sizes and impeller diameters to meet specific flow and head requirements within a system.
