Mini Micro Submersible Motor Pump (Water Pump) DC 3-6V 120L/H Low

A tiny submersible pump that runs from 3 to 6 volts, low enough to drive from a battery pack or a USB supply. At 120 litres per hour it is aimed at small-scale work: automatic plant watering, desktop fountains, model waterfalls and classroom demonstrations. It must stay submerged to stay cool, so it should never run dry. Switch it through a transistor or relay rather than an Arduino pin. Runs from a low voltage battery or USB supply; Small enough for plant watering and desk projects; Fully submersible, very quiet in operation; Very low cost for automated watering builds.
