A21802C-335 Cornell OEM Drive Coupler

The A21802C-335 Cornell OEM Drive Coupler is a coupling designed for Cornell Pump Company centrifugal pump platforms. Cornell pumps are used extensively in agriculture, municipal water, food processing, and industrial fluid handling, and the drive coupler provides the flexible connection between the prime mover (engine or motor) and the pump shaft. These couplings use a heavy-duty elastomeric element to absorb torsional vibration from the prime mover while transmitting torque to the pump impeller. In pump applications, coupler condition directly affects pump performance – a worn element allows vibration to reach the pump bearings and mechanical seal, leading to premature failure and costly downtime.

The A21802C-335 is a direct OEM replacement for the factory coupling. During installation, verify pump-to-motor alignment per Cornell’s specifications and inspect the coupling hub bores for wear. Proper alignment is critical in pump applications where even minor misalignment accelerates seal and bearing wear.
