Wind-driven water pumps work by using the wind that the blade catches to turn the wheel, which moves the other parts of the system to lift and drop the pump rod to begin the pump cylinder's movement of water, states HomePower.com. As long as the wind wheel is moving, the pump piston is moving to pump the water. The speed at which the water pumps through depends on the speed of the wind.
Wind-driven water pumps, also known as wind pumps, are a type of windmill and are commonly found throughout the Netherlands. They contain several parts including windmill blades, a rotor, a shaft, pinion gears, bull gears, pitman arms, a yoke, a pump rod, a pump cylinder, a piston and check valves. Once the wheel begins to move, it causes the shaft to move the pinion gears; these move the bull gears, which move the pitman arms. The pitman arms move the yoke up and down, causing the pump rod to move up and down.
The pump rod moves the piston. As the piston rises, water moves through the lower check valve into the pump cylinder. When the pump rod lowers, the lower check valve closes and the piston check valve opens. From there, water passes through the pump cylinder to its final location.
