A218020-335 Cornell Pump OEM Drive Coupler

The A218020-335 Cornell OEM Drive Coupler is a torsional coupling for Cornell Pump Company centrifugal pump platforms.

Cornell’s 335-series torsional couplings connect the prime mover – to the pump shaft through a heavy-duty elastomeric element. This flexible connection absorbs the torsional vibration that would otherwise reach the pump’s mechanical seal and bearings, which are the most common failure points in centrifugal pump systems. In irrigation and dewatering applications where pumps run for extended periods under variable load, coupler condition directly affects seal life and overall pump reliability.

The A218020-335 is a direct factory replacement. During installation, verify pump-to-driver alignment using dial indicators per Cornell’s specifications. Inspect hub bores and keyways before installing the new coupler. Proper alignment is the most important factor in both coupler and mechanical seal longevity.
