A21763Y-335 Cornell OEM Drive Coupler

The A21763Y-335 Cornell OEM Drive Coupler is an original equipment coupling for Cornell Pump Company centrifugal pump systems. This coupling connects the prime mover to the pump shaft, providing torsional damping and vibration isolation that protects pump bearings and mechanical seals from engine or motor vibration.

Cornell pumps serve demanding applications in agriculture (irrigation, flood control, crop processing), municipal water systems, aquaculture, and industrial fluid transfer. The drive coupler in these systems handles the torsional loads generated during pump startup, load changes, and continuous operation.

This is a direct OEM replacement that matches the factory coupling’s dimensions, elastomer specification, and mounting configuration. When replacing, check pump-to-motor alignment with dial indicators, inspect both hub bores, and follow Cornell’s installation procedure. Confirm smooth operation at full pump speed and load before returning to service.
