BMN043A-A02 Cornell OEM Drive Coupler

The BMN043A-A02 Cornell OEM Drive Coupler is a factory coupling assembly for Cornell Pump Company pump systems. This coupler provides the flexible connection between the prime mover and the pump input shaft, handling torsional loads while isolating vibration in continuous-duty pumping applications.

Cornell pumps are built for high-flow, high-efficiency service in agriculture, industrial process, and municipal applications. The drive coupler in these installations takes the brunt of startup torque and handles the dynamic loads created by varying flow rates and fluid conditions. Proper coupler function is essential for protecting the pump mechanical seal and bearings from the vibration damage that leads to premature failure and unplanned downtime.

The BMN043A-A02 is a Cornell factory part that installs in the original mounting arrangement. During installation, ensure both shafts are clean and free of nicks or burrs, verify proper engagement depth, and align the pump and driver assembly to within the tolerances specified in the Cornell installation manual.
