Abstract

See full text

A centrifugal pump and an impeller thereof are provided. The impeller defines an outer peripheral edge which includes a plurality of serrations circumferentially thereon. The plurality of serrations are configured such that additional power and momentum are transferred to a working fluid of the pump, which results in an additional pressure rise in the working fluid at relatively low flow rates of the centrifugal pump.
