Definition -A Casing Ring is a replaceable ring fitted inside the casing of a pump to protect the casing from wear and erosion caused by the rotating impeller and fluid flow. Its purpose is to maintain proper clearances, reduce internal leakage, and preserve pump efficiency. Casing rings are commonly used in centrifugal and volute pumps in industrial, water, and process applications.
