SunPumps' SDS-Q of submersible solar-direct pumps are high-efficiency positive displacement pumps for well casings 4" and larger. Constructed of super-strong stainless steel, these pumps are durable, corrosion-resistant, and highly economical.
The SDS-D series was the very first diaphragm submersible pumps introduced for solar-direct use in 1988, and have decades of proven performance history. They operate on 12-30 VDC that can be supplied from solar panels, batteries, or other sources. These durable, versatile pumps are great for off-grid living and agriculture applications.
At 30VDC, the SDS-D-128 can move water at up to 1.6 gallons per minute or up to 230 feet high. See the spec sheet linked below for the full output curve.
