A windpump is a type of windmill which is used for pumping water.The multi-bladed wind pump or wind turbine atop a lattice tower made of wood or steel hence became, for many years, a fixture of the landscape throughout rural America.

These mills, made by a variety of manufacturers, featured many blades so that they would turn slowly with considerable torque in moderate winds and be self-regulating in high winds. A tower-top gearbox and crankshaft converted the rotary motion into reciprocating strokes carried downward through a rod to the pump cylinder below.
A typical wind water pumping system includes: the wind rotor, a tower, a mechanical pump, mechanical linkage, a well full of water (or other such water source), and piping to deliver the pumped water.

The wind rotor is connected to a gearbox and crankshaft which converts its rotary motion into reciprocating up-down motion on a pump rod which is connected to a piston in the pump at the bottom of the well pipe.When the piston is lifted by the piston rod, the piston lifts the entire volume of water above it, and the water flows out of a discharge pipe at the top.
