Wind water pumps are a type of windmill; they use the movement of the wind on the wheel blades to pump water through the system using a set of pistons and cylinders. The water pump is dependent on the wind; the faster the speed of the wind through the blades, the quicker the water moves through the pump. Wind water pumps are found throughout The Netherlands.
Wind water pumps are comprised of many different parts, all of which work together to move water. These parts include blades, a rotor, pinion gears, bull gears, a shaft, a yoke, a pump rod, Pitman arms, a pump cylinder, a piston and two check valves. The wind starts the process of the movements of the parts to push through the water. For example, when the wind moves the wheel, it forces the shaft to start moving the pinion gears, which then move the bull gears.
The bull gears start the movement of the Pitman arms, which in turn causes the yoke and pump rod to move up and down. The movement of the pump rod causes the piston to rise. Water is then moves through the lower check valve into the pump cylinder until the pump rod begins to lower. The lowering of the pump rod opens up the piston check valve to allow water to pass through the cylinder.
