A21802R-335 Cornell Pump OEM Drive Coupler

The A21802R-335 Cornell OEM Drive Coupler is a coupling for Cornell Pump Company centrifugal pump platforms. This A21802-series coupler serves Cornell’s larger pump frame sizes in applications requiring sustained torque transmission and effective vibration damping.

In municipal and industrial pump stations, these couplers operate in enclosed pump houses where heat buildup can accelerate elastomer degradation. In agricultural settings, they face exposure to dust, moisture, and temperature extremes.

Replace the coupling when inspection reveals cracking, glazing, or deformation of the elastomeric element. During installation, verify pump-to-driver alignment with dial indicators and torque all fasteners per Cornell’s specification. Run the pump through its full operating range and check for abnormal vibration before returning to service.
