SDS DC Submersible Pumps
SunPumps SDS series submersible pumps are efficient, low voltage, DC powered, diaphragm type positive displacement pumps designed specifically for water delivery in remote locations. They operate at 12 to 30 volts DC which may be supplied from a variety of independent DC power sources. There are two models of SDS pump. The D-series has a dual diaphragm and fits in a 4-inch well. The Q-series is a higher flow pump that fits in 5-inch or larger wells. They can be used to fill an open tank or in pressurized water delivery systems. Simplicity is the key feature of the SDS series pumps. They are easy to install, require very little maintenance and are repairable. Use the table to choose the pump that best meets your flow need at a given head. A PCA-30-M1 controller must be used with all SDS pumps. At 15 volts, flow is slightly less than half of the 30-volt flow.
