Barwig 02 Low voltage impeller pump 1200 l/h 12 V

These high-performance external pumps are ideal anywhere that a submersible pump cannot be used. As it is not self-priming, the pump should be placed at a level lower than the bottom of the water tank concerned. This is the most effective way of preventing the pump from running dry. And since they can be powered either from a car battery or via a mains adaptor, you have complete flexibility regarding setup location and power source.
