The Super Twister 12 volt pump is capable of pumping up to 85 feet from at an amazing 1.0 gallon
per minute from ground level by simply connecting the pump to a 12 volt battery. This Revolutionary 3 stage pump has a constant voltage booster (CVB) built into the pump. The (CVB) outputs a constant voltage to the Super Twister Pump motors which reduces voltage drop due to battery drainage. What does that mean? A more continuous and faster discharge rate! The Super Twister reliable design is suitable for continuous sampling or purging of groundwater wells.
