Abstract
According to one embodiment of the present invention, a system for pumping fluid is provided. According to this embodiment, a fluid pumping system comprises a fluid inlet pipe and a fluid outlet pipe. A plurality of pump units are disposed between the inlet and outlet pipes such that the pump units each pump fluid out of the inlet pipe and into the outlet pipe. The pump units each include at least one DC motor. A solar panel may be used to power the pump units.
Claims6
A water pump system comprising:
- a preexisting water pump system including a preexisting water pump having a first horsepower rating;
- and
- a supplemental retrofitted pump system selectively bypassing said preexisting water pump system, said supplemental retrofitted pump system comprising:
- inlet bypass pipe;
- outlet bypass pipe;
- a plurality of check valves configured to periodically direct water away from the preexisting water pump system and through the supplemental retrofitted pump system and also to periodically direct water away from the supplemental retrofitted pump system and back through the preexisting water pump system;
- and
- one or more pump units, each having a second horsepower rating, wherein the total horsepower rating of the one or more pump units in the supplemental retrofitted pump system is less than ½ of said first horsepower rating, wherein the water pump system further comprises a photovoltaic solar panel providing electrical power to said one or more pump units.
