A21802B-335 Cornell Pump OEM Drive Coupler

The A21802B-335 Cornell OEM Drive Coupler is a coupling for Cornell centrifugal pump systems. This is the complete coupling assembly including hubs and elastomeric element, designed for the A21802 pump size class.

Cornell pumps equipped with A21802-series couplers are mid-to-large frame units serving demanding applications: agricultural irrigation systems moving thousands of gallons per minute, municipal water transfer stations, food processing hydro-transport lines, and industrial dewatering operations. The coupling must reliably transmit torque while isolating the pump’s precision components from engine or motor vibration.

When the elastomeric element in the coupler degrades, early warning signs include increased vibration at the pump bearing housings, mechanical seal weepage, and audible noise from the coupling guard area. Replacing the coupler promptly prevents expensive downstream damage. Install per Cornell’s procedure with careful attention to alignment and hub fit.
