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.
