The A21802G-335 Cornell OEM Drive Coupler is a complete coupling assembly for Cornell Pump Company centrifugal pump systems in the A21802 size class.
The A21802G complete coupling includes both hubs and the elastomeric element as a single assembly. This is the appropriate part when hub inspection reveals wear, scoring, or dimensional changes that make element-only replacement inadvisable. Cornell’s larger pump platforms in agriculture, municipal water, and industrial service generate significant torque that the coupling must transmit reliably while damping vibration.
The A21802G-335 is a direct factory replacement. During installation, verify pump-to-driver alignment using dial indicators per Cornell’s specifications. Proper alignment protects both the new coupling and the pump’s mechanical seal from premature wear.
