The A21802F-335 Cornell OEM Drive Coupler is a torsional coupling specified for Cornell Pump Company centrifugal pump platforms in the A21802 size class.
Cornell’s centrifugal pumps serve applications from agricultural irrigation and flood control to municipal wastewater, mining dewatering, and food processing. In each of these environments, the drive coupler protects the pump’s mechanical seal and bearings from the torsional pulses generated by the prime mover. A worn coupling allows vibration to pass through to the pump, accelerating seal wear and shortening bearing life – the two most common and expensive pump maintenance issues.
The A21802F-335 is a direct OEM replacement. Verify your pump model and coupling configuration against Cornell’s parts documentation before ordering. During installation, use dial indicators to confirm alignment between the prime mover and pump shaft. Torque all fasteners to specification and run the pump through a full operating cycle to verify smooth performance.
