Definition -A Case Wear Ring is a replaceable ring fitted inside the casing of a pump to protect it from wear caused by friction and fluid flow between the casing and the impeller. Its purpose is to reduce leakage, maintain efficiency, and prevent damage to the pump casing. Case wear rings are commonly used in centrifugal and volute pumps, especially in industrial and water-handling applications.
