A21763T-335 Cornell OEM Drive Coupler

The A21763T-335 Cornell OEM Drive Coupler is an original equipment coupling assembly for Cornell Pump Company centrifugal pumps. This coupler connects the engine or motor to the pump shaft, providing torsional vibration isolation in demanding pumping applications.

Cornell pumps are deployed in agriculture, municipal water and wastewater, mining dewatering, and industrial process applications. These pumps handle everything from clean water to heavy slurry with abrasive solids, and the drive coupler must transmit full motor torque while absorbing the shock loads that come with variable flow conditions and occasional solids passage. The coupler also protects the pump bearings and mechanical seal from vibration damage that shortens service life.

The A21763T-335 is a factory-specified assembly that matches the original hub pattern and elastomer specifications for the intended Cornell pump model. Clean both shaft ends, verify keyway condition, and align the pump and driver per Cornell installation guidelines before torquing mounting hardware.
