SunPumps SDS-D series submersible pumps are one of the highest quality, low voltage 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. Note: 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 the SDS-D-228 but with a higher flow rate. We do not have updated pump curves for over 115 foot depth, but max flow rate will be around .75 GPM at 225 feet. The SDS-D-128 requires a minimum 4" well casing. Pumps up to 2 gallons per minute. Two year warranty.
