A21802X-335 Cornell Pump OEM Drive Coupler

The A21802X-335 Cornell Pump OEM Drive Coupler is an OEM coupling for Cornell Pump Company pump installations. This drive coupler manages the torsional connection between the prime mover and the pump, absorbing vibration while transmitting rated torque.

Cornell pumps are built with efficiency as a core design principle, and the drive coupling is part of the system that keeps the pump running smoothly. A worn or degraded coupling allows excess vibration to reach the pump, which increases energy consumption, accelerates bearing wear, and shortens mechanical seal life. In high-volume pumping operations where equipment runs extended hours, coupling condition directly affects both operating costs and maintenance frequency.

The A21802X-335 drops directly into the factory mounting arrangement on the intended Cornell model. During service, remove the old coupling components, clean shafts, and install the new assembly with proper alignment confirmed per the Cornell technical documentation.
