Disclosed is a centrifugal pump having a housing, an input and an output port, and a driven impeller. Surrounding the impeller is a turbine means which serves to retrieve at least part of the kinetic energy imparted by the impeller to the pumping medium. The energy retrieved by the turbine means can be used to apply additional power to a prior auxiliary stage, an after auxiliary stage, or back to the original impeller itself. In this manner, the turbine retrieves kinetic energy which might otherwise be wasted and, therefore, the turbine improves the overall efficiency of the pump. Stationary flanges at the discharge end of the pump jacket serve to convert the remaining curvilinear motion of the water column into a non-revolving column of water. The stationary flanges also help to avoid a drop in the operating pressure at the discharge end of the jacket.
A system for pumping fluids comprising, a housing having a central inlet and a central outlet, an impeller mounted for rotation in said housing, said impeller having a peripheral surface and a plurality of radially extending slots therein extending from the center thereof to said peripheral surface, power means for rotating said impeller whereby the fluids are drawn in through said inlet and through said radially extending slots to said peripheral surface thereby imparting curvilinear and radial motion to said fluid, a plurality of radially extending fluid slowing guide vanes located on said housing near the fluid outlet, and means between said impeller and said vanes for retrieving the energy of said curvilinear motion, said radial motion forcing said fluid to said outlet, and said outlet being disposed axially downstream relative to said impeller.
A system for pumping fluids comprising, a housing having a central inlet and a central outlet, an impeller mounted for rotation in said housing, said impeller having a peripheral surface and a plurality of radially extending straight slots therein extending from the center thereof to said peripheral surface, power means for rotating said impeller whereby the fluids are drawn in through said inlet and through said radially extending straight slots to said peripheral surface thereby imparting curvilinear and radial motion to said fluid, a plurality of fluid slowing radially extending guide vanes located on said housing near the fluid outlet, and means between said impeller and said vanes for retrieving the energy of said curvilinear motion, said radial motion forcing said fluid to said outlet.
