Abstract
A pump impeller for use in industrial pumps of the centrifugal type is disclosed in which the vanes of the pump impeller are particularly configured to maintain pumping efficiency as the vane wears over continuous use or operation of the pump. The impeller vane is configured to continuously present an aggressive cutting surface at the leading edge of the vane even though the vane may become degraded and worn through continuous use.
