ABSTRACT:
A centrifugal pump is constructed of a cast iron impeller and corrosion resistant means for providing a minimal clearance space between the impeller and the volute body of the pump in the form of a clearance ring mounted in the volute body to cooperate with a stainless steel tubular insert member cast into the impeller hub. The clearance ring may comprise a bendable ring which may be compressed from its normal condition to fit into a bore in the volute body so as to spring outwardly into its mounted position.
