Sun Pumps SDS-D-128 Solar Submersible Pump .4 – 1.5 GPM is one of the most highest quality, low votage DC pumps on the market. They were the first diaphragm submersible introduced to the solar industry in 1988 and have an excellent performance record.
The SDS series pumps are easy to install by hand without any special equipment. The pump includes a double shrink splice kit and a 1/2″ brass discharge fitting.
The design is an off-spring of the already time proved SDS-Q series pump. There are three standard models to choose from using 304 Stainless Steel housings and hard-ware. The same pumps can be special ordered 316 Stainless Steel housings and hardware for highly corrosive water. They operate on 12 to 30 volts DC that may be supplied from a variety of independent sources including solar panels or batteries. It is the ideal way to provide water for remote homes, campsites, livestock, small farms or for many other needs beyond the power grid.
The depth capabilities of the SDS-D-128 has been expanded from 115 feet to 230 feet starting in June 2005. It now has the same depth rating as our SDS-D-228 but with a higher flow rate.
