A water well pump is 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 manually operable water well pump includes a baseplate with a casing thereon, a rocker arm pivotally mounted in the casing for reciprocating movement therein, a chain on one end of the rocker arm outside the casing for reciprocating vertical movement with the rocker arm.
A connector on the free end of the chain for connecting the latter to a pump rod, whereby the rod can be reciprocated in a well casing, the transmission in the casing including a pair of gears interconnected by an endless chain, a crank for rotating the smaller of the gears and a linkage between the larger of the gears and the other end of the rocker arm for reciprocating the latter, and a tank suspended from the baseplate concentric with the pump rod for mounting on a well casing to receive and discharge water from the well.
