The A21802G-335-ELEM Cornell OEM Coupling Element is the replaceable elastomeric insert for the A21802G-335 coupling in Cornell centrifugal pump systems. This element serves the A21802 coupling class, providing torsional vibration isolation for Cornell’s larger pump platforms.
Element replacement is a routine maintenance item on Cornell pumps. The recommended practice is to inspect the coupling at every scheduled pump service – every 2,000-4,000 operating hours depending on the application severity. In harsh environments like mining or wastewater service, more frequent inspection may be warranted. Replacing the element proactively before failure prevents the vibration damage that occurs when a degraded element can no longer effectively dampen torsional forces.
Verify the full part number including Clean and inspect both hubs before installing the new element. Follow Cornell’s installation and alignment procedure.
