A21802M-335 Cornell Pump OEM Drive Coupler

The A21802M-335 Cornell OEM Drive Coupler is a coupling for Cornell Pump Company centrifugal pump systems in the A21802 size class. Cornell’s engine-mounted and frame-mounted pumps in this size range are workhorses in agricultural irrigation, municipal pumping stations, and industrial water transfer. Using the correct variant ensures the coupling’s torsional characteristics match the drivetrain, which is essential for proper vibration control and mechanical seal protection.

In agricultural service, these pumps operate seasonally at high duty cycles – running continuously during irrigation season, then sitting idle. The elastomeric coupling element degrades both from use and from environmental exposure during idle periods. Inspect the coupler at the start of each season and replace if cracking or deformation is visible.
