Bell & Gossett 118431LF 2-3/4″ Bronze Impeller (Series 100)

The Bell & Gossett 118431LF is a lead-free bronze impeller with a 2-3/4″ outside diameter. This impeller repairs Series 100 pump models 100-BI and 100-AB. The impeller is a rotating component within the pump casing that transfers mechanical energy from the motor to the fluid being pumped. The main purpose of a pump impeller is to convert the rotational energy from the motor into kinetic energy in the fluid. As the impeller rotates, it creates a centrifugal force that pushes the fluid away from the center of rotation, causing it to move outward and thus create flow.
