Abstract
A centrifugal pump having a turbine impeller having a plurality of curved vanes. The vanes curve from the inlet end to the outlet end in the direction of pumping rotation of the impeller, such that the leading wall of each vane re-directs a portion of the radial velocity of the fluid flowing through the passage to increase the total tangential velocity provided by the impeller. Each curved passage has cooperating inlet and outlet areas and a smooth curved shape to ensure that the radial velocity of the liquid does not decrease dramatically while flowing through the passage, while ensuring that any solid particulates and contaminants entering the impeller will pass therethrough.
