Ruhrpumpen wear ring casing, part numbers 4CF000245 and 20W0302, is a replaceable casing wear ring for Ruhrpumpen centrifugal pumps. It measures 12x16x17A and has an overall length (OAL) of 13-1/4 inches. Wear rings like this provide close running clearance between the pump casing and impeller to minimize leakage between suction and discharge chambers, helping preserve efficiency, and are designed to be replaced during routine maintenance. Ruhrpumpen's OEM spare-parts program includes casing wear rings as part of its available parts for pump systems, and the company can manufacture parts or supply replacements for a range of models.
