A21802N-335 Cornell Pump OEM Drive Coupler

The A21802N-335 Cornell OEM Drive Coupler is a torsional coupling for Cornell centrifugal pump platforms in the A21802 size class. This coupling connects the prime mover to the pump shaft while providing torsional vibration isolation that protects bearings and mechanical seals.

Cornell pumps are recognized for their efficiency and durability in demanding fluid handling applications. The drive coupler plays an essential but critical role in maintaining that reliability – it absorbs the cyclic forces generated by diesel engines and electric motors that would otherwise fatigue pump internals over time. In high-hour applications like continuous municipal pumping or extended irrigation runs, coupler condition has a measurable impact on overall pump maintenance costs.

The A21802N-335 is a direct factory replacement that matches the OEM dimensions and elastomer specification. During installation, follow Cornell’s alignment procedure and inspect all coupling hardware. Verify smooth operation at the pump’s normal operating speed and pressure before leaving the site.
