Independent Water Systems

While 120 volt AC pumps are great for pumping water out of a well and straight into a diaphragm (pressurized) tank, these DC pumps are used primarily for moving water from your well, springhead cistern, etc. to another cistern above your house. In other words, a non-pressurized use, where all you want to do is move water with the least amount of electricity. For applications like these, DC water pumps excel, because they require less electricity to operate than the 120 volt AC pumps and can be run straight from batteries or (for certain models) directly from solar panels. DC submersible pumps are not generally used for supplying pressurized water straight to a house because they pump slower than their AC counterparts. Once again, they are great water movers. ETA is one of the leading DC pump manufacturers with at least one pump capable of lifting water to a cistern from a 600 foot static water level. Grundfos also manufactures the SQ Flex series of pumps that can run on many different voltages. This pump is not cheap, but it might be a necessity if the static water level of your well is very deep.
