Bell & Gossett 189169LF 2″ Noryl Impeller for Series PL

Bell & Gossett 189169LF, lead-free Noryl pump impeller with a two-inch outside diameter. This impeller repairs Series PL booster pumps, models PL-50, PL-50B, PL-75, and PL-75B. 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.
