Abstract
A water well pump is shown which uses regenerative turbine technology. A submersible electric motor has an output shaft which drives multi-stage regenerative turbine stages of the pump. The various stages are made up of turbine impellers separated by intermediate plates. The turbine impellers have peripheral vanes which cooperate with surrounding scraper rings to form flow channels through the regenerative section of the pump and impart energy to the water passing through the pump. The pump can be powered by a low energy source, such as a solar panel.

A water well pump used to supply water from a downhole subterranean location within a wellbore to a surface location by means of surface plumbing, the pump comprising:
- an electric motor positionable within the wellbore and having an associated electrical supply cable extending from the well surface to the downhole location for supplying electric current to the motor, the electric motor having a rotatably driven output shaft, the shaft extending outwardly from the motor generally along a central axis of the wellbore;
- a pump sleeve and associated suction case generally aligned along the axis of the motor output shaft, the suction case having at least one opening for receiving well water;
- a plurality of regenerative turbine stages contained in a stacked arrangement within the pump sleeve and coupled to the shaft for rotary motion as the motor drives the shaft, the regenerative turbine stages forming a regenerative turbine section of the pump having an inlet for receiving well water from the suction case and having an outlet port connected to the surface plumbing for supplying well water to the surface location.
A water well pump used to supply water from a downhole subterranean location within a generally vertical wellbore to a surface location by means of surface plumbing, the pump comprising:
- an electric submersible motor positionable within the wellbore and having an associated supply cable extending from the well surface to the downhole location for supplying electric current to the motor, the electric motor having a rotatably driven output shaft, the shaft extending outwardly from the motor generally along a central vertical axis of the wellbore;
- a cylindrical pump sleeve and associated cylindrical suction case generally aligned along the vertical axis of the motor output shaft, the suction case having at least one opening for receiving well water;
- a plurality of regenerative turbine stages contained in a stacked arrangement within the pump sleeve and coupled to the shaft for rotary motion as the motor drives the shaft, the regenerative turbine stages forming a regenerative turbine section of the pump having an inlet port for receiving well water from the suction case and having an outlet port connected to the surface plumbing for supplying well water to the surface location;
- and
- wherein the regenerative turbine stages include a plurality of impellers separated by intermediate plates, the impellers having a series of peripheral turbine vanes located on each of opposing sides thereof for moving water through the regenerative turbine section of the pump between the inlet port and outlet port thereof.
A method of pumping water from a downhole subterranean location within a wellbore to a surface location, the method comprising the steps of:
- locating an electric submersible pump within the wellbore at a selected downhole location, the submersible pump having an associated supply cable extending from the well surface to the downhole location for supplying electric current to the pump, the pump also having an inlet port for receiving well water and having an outlet port for supplying water to the surface location by means of intervening plumbing;
- wherein the submersible pump is a multi-stage, regenerative turbine pump which has a plurality of regenerative turbine stages arranged in-line along a vertical axis generally parallel to a central axis of the wellbore
