Bell & Gossett 186003 – Coupler for Series PD and Series 60 Pumps
Complete pump coupling comprised of two flanges and one rubber sleeve (insert). 5/8″ x 5/8″ shaft size. Fits PD-38, 39, 40 Bell & Gossett booster pumps. Pump couplings (a.k.a. pump couplers) connect the motor shaft to the pump shaft. When the pump coupler “breaks” it signals the motor mounts, located on each end of the motor, have lost their resiliency and need to be replaced. Therefore, order two replacement pump couplers (always keep a spare – These babies always break in January!) and a set (pair) of the appropriate motor mounts.
