Bell & Gossett P50822 Series 1531-5BC Impeller 9½” Small Bore

The Bell & Gossett P50822 is a trimmable bronze impeller with a 9-1/2″ outside diameter. It repairs Series 1510 and Series 1531 end suction pump models 5BC with 1-1/4″ pump shafts. 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.
