The new SunRotor Helical Rotor Submersible Solar Pumps allows for maximum functional lift capability of up to 425 feet. Powered by solar, battery, or a combination of the two, maximum flow at 100 feet can be up to 15.1 gallons/minute. These submersible water pumps offer a broad range of pumping capabilities with greater water pumping depths and higher volumes of water. These pumps must be used with the SunRotor Controller, in order to avoid pump failure, and void the pump warranty.
