ABSTRACT:
A variable geometry centrifugal pump varies the pump output and/or centrifugal pump force by varying the effective radial length of the impeller vanes impelling fluid. The pump provides an impeller having graduated vanes with a shorter vane section for low output and a longer vane section for high output. A shroud carried in the impeller has female openings for the vanes to extend through to cover shorter or longer sections of the vanes. The shroud includes apertures for the axial pump inlet to extend through, thereby permitting the impeller to impel fluid on either side of the shroud.
