The Cornell 4NHTB Impeller Washer is a replacement pump component designed for compatible Cornell 4NHTB pumps. Cornell parts documentation specifies this impeller washer at .66″ x 3.00″ x .75″ and lists one washer per impeller assembly.

The impeller washer is part of the hardware used to secure the impeller to the pump shaft. It provides a solid bearing surface for the impeller lockscrew and helps distribute the clamping force across the impeller connection.

During pump operation and maintenance, the washer can experience wear, corrosion, deformation, or damage. A worn or distorted washer can interfere with proper impeller installation and fastening. Inspecting and replacing the impeller washer when servicing the impeller helps maintain a secure and properly assembled rotating system.

Cornell documentation identifies impeller washers as standard maintenance components used in pump repair and rebuilding. Verify the 4NHTB pump model and .66″ x 3.00″ x .75″ dimensions before ordering.
