Grundfos SQFlex Submersible Pumps The Grundfos SQFlex are industry-leading submersible pumps for water lifts of up to 800 feet. SQFlex pumps can be directly powered by a PV array or can be run on an inverter, generator, 48 VDC battery, utility grid, or any combination of these sources. Virtually any source of power, 30 to 300 VDC or 90 to 240 VAC, can be used to run these pumps.
SHURflo 9300 Submersible Pump The SHURflo 9300 is a positive displacement diaphragm pump with very high efficiency; however, its diaphragm should be replaced every 2 to 4 years, depending on the pumping volume. The SHURflo 9300 can be operated on a 12 or 24 VDC battery, or using a SHURflo pump controller, directly with a PV array.
Aquatec SWP-4000 Submersible Pump The Aquatec SWP-4000 submersible pump is designed for home or livestock water needs in off-grid locations. It is a positive-displacement diaphragm pump, constructed with high-grade materials and is NSF approved for potable water use. Aquatec SWP-6000 The new Aquatec SWP-6000 is a larger version of the SWP-4000 model, providing all the same features while allowing for greater pumping volume from depths to 80 feet.
