SDS DC Submersible Pumps

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.

PCA/PCB Controllers

SunPumps PCA and PCB Series pump controllers are microprocessor-controlled DC power converters designed as the interface between a DC-powered pump and the power source. The DC source may be solar modules, batteries or systems using wind generators. The primary function of the PC series controller is to boost the current of solar modules in low sunlight conditions while holding the voltage of the solar modules at the maximum power point. This allows a pump to start earlier in the morning and stay running longer in the evening. SunPumps PC series pump controllers have many unique features designed specifically for water pumping.

All PC series controllers include a pump speed control circuit, a remote switch circuit, a sensor-less low-water cut-off circuit, an electronic circuit breaker, and indicator lights. SunPumps PCA 30-M1D controller uses the same controller board with all the same features as the PCA 30-M1 controller. The only difference is the box is constructed of UV stabilized Super Tuff Delrin instead of aluminum and the current rating is reduced from 8 amps to 6 amps.
