Solinst’s 12V Submersible Pump and 12V Pump Controller are lightweight, portable, and easy to set up, deploy and operate. The pump’s sleek, short design (nominal 6") ensures it fits easily down wells that may not be straight. The 12V Submersible Pump cable connects to the 12V Pump Controller, which then clips to a 12V power source. The pump is capable of pumping groundwater from 36.5 m (120 ft.) below ground surface, with flow rates up to 13.5 L/min (3.6 U.S. gpm) in shallow conditions. The continuous flow rate is very easy to adjust using the controller’s single dial.
