Make fountains or plant-watering projects with this submersible water pump. It's great for beginner projects and super easy to use! The pump is basically a DC motor that is powered with 3V and draws 100mA. When powered, the pump sucks water in from the side of the plastic casing and pushes it out the tubing port. The pump must be primed by keeping it inside water at all times. Reversing the polarity does not turn it into a suction device, it will only pump water! https://elecena.pl/product/17502609/submersible-3v-dc-water-pump-1-meter-vertical-type 2021-04-07 https://elecena.pl/product/17502609/submersible-3v-dc-water-pump-1-meter-vertical-type 2021-05-06
