The Berkeley S15405 impeller hub spacer is a replacement spacer for selected Berkeley centrifugal pump assemblies. Its 7/8-inch inside diameter and 1-1/8-inch outside diameter help distinguish it from other rings and spacers used around the pump shaft.
Made from 304 stainless steel, this component belongs at the impeller hub rather than in the bearing or shaft-seal position. Match the complete pump catalog number and the spacer location before ordering; similar-looking rings can have different jobs within the same pump.
