Archimedes' screw, also known as the water screw, screw pump or Egyptian screw, is a machine used for transferring water from a low-lying body of water into irrigation ditches. Water is pumped by turning a screw-shaped surface inside a pipe. Archimedes screws are also used for materials such as powders and grains.

Archimedes screw pumps consist of a screw (a helical surface surrounding a central cylindrical shaft) inside a hollow pipe. The screw in this case is turned by a
