SunPumps' SDS-T of submersible DC well pumps are high-efficiency positive displacement pumps for well casings 4" and larger. Constructed of super-strong Ryton and stainless steel, these pumps are durable, corrosion-resistant, and highly economical. They operate on 12-30 VDC that can be supplied from solar panels, batteries, or other DC sources.
At 30VDC, the SDS-T-128 can move water at up to 1.6 gallons per minute or up to 230 feet high. See the document linked below for output curves at other voltages.
The SDS-T pumps are based on SunPumps' time-tested SDS-Q series pumps, but can be installed a bit deeper and have a smaller ½" port than the SDS-Q's ¾". These durable, versatile pumps are great for off-grid homesteads, small farms, campsites and other off-grid applications where well water delivery is needed.
SDS-T series pumps are designed to work with a SunPumps controller. In addition to maximizing the SDS-T pump's performance and protecting both the pump and the power source, a SunPumps brand pump controller (available separately on the "Accessories" tab) must be used in conjunction with this pump in order to validate this pump's warranty.
