The Engineered Plastic Super Twister® pump is capable of pumping up to 85 feet from ground level by simply connecting it to a 12 volt battery. This Revolutionary pump has our constant voltage booster technology (CVBT) built in. With the new built in booster the problem of tubing blowing is eliminated. If your battery should fall below 10.75 volts, the built in booster will recognize the low voltage and the pump will start pulsating. In short, this is an indicator of a low battery. The CVBT outputs a constant voltage to the Super Twister® Pump motors which reduces voltage drop due to battery drainage.
