Pump impeller with enhanced vane inlet wear

摘要

Disclosed is a centrifugal pump having inlet blade angles set to an angle which takes into account the velocity of the solids moving within a slurry steam to reduce the wear on the centrifugal pump. The centrifugal pump includes an impeller for moving the slurry. The impeller includes a plurality of vanes, wherein each vane has an inlet angle optimized for providing a substantially shock-free entry of slurry into the pump relative to a velocity profile of the solids contained within the lower half of the slurry profile to reduce wear on the pump.
