Little Donkey Pump - A Cylinder and Piston Pump

In this video we build a piston water pump also known in some countries as a Donkey Pump.
Its operation consists of a cylinder with a piston that, when performing a back-and-forth movement, causes water to enter and leave the pump. One-way valves or check valves make the water always enter on one side and leave on the other, thus allowing it to be carried from one level to another.
This water pump is driven by a small 12V electric motor.

Seria interessante um sistema biela+ manivela, daí não precisaria articular o cilindro do pistão com a dobradiça. (E menos durepoxi tbm kk) mas ficou bem legal. Parabéns 👏🏻
