Abstract
A impeller for a centrifugal pump has an inducer section. The inducer section has first and second pluralities of blades, each having a plurality of polygonal cross-sections defined by a plurality of vertices. The pluralities of vertices are defined by tables of vertex locations. A method of making a centrifugal pump includes forming an impeller that has an inducer section, as described above, and an impeller section. The impeller is fluidly connected downstream of the inducer section and has third, fourth, and fifth pluralities of blades, each having a plurality of polygonal cross-sectional areas defined by a plurality of vertices. The pluralities of vertices are defined by tables of vertex locations.
