Wear Ring in the Centrifugal Pumps based on - API 610

These rings are called “case” and “impeller” wear rings. Most pumps for refinery and heavy duty chemical plant appli ions are designed with close clearances between the impeller and pressure casing to separate the discharge pressure zone of the impeller from the inlet pressure zone and minimize back leakage or slip flow. Wear rings are fitted at the close clearance lo ion in the pump casing and usually at an opposing position on the impeller.:2
