A21502M-335 Cornell Pump OEM Drive Coupler

The A21502M-335 Cornell OEM Drive Coupler is a torsional coupling for Cornell Pump Company centrifugal pump platforms in the A21502 size class. This coupling family covers a specific frame size range in Cornell’s pump lineup, with

Cornell’s SAE engine-mounted pump configurations are popular in agricultural and portable pumping applications, where the pump bolts directly to a diesel engine using an SAE adapter housing. In this mounting arrangement, the drive coupler sits inside the bell housing and must be precisely matched to both the engine flywheel and pump shaft. The A21502M-335 is configured for this type of installation on its target pump models.

During replacement on engine-mounted configurations, the pump must be separated from the engine housing to access the coupling. Follow Cornell’s procedure for this process, paying attention to dowel pin alignment during reassembly. Verify coupling-to-flywheel and coupling-to-pump-shaft fit before bolting the housing back together.
