Graph of the Volume-per-Turn Ratio Archimedes screw pumps are one of the most efficient methods of pumping water and as such are employed in a wide range of applications. As the screw turns, the water slides along the tube. It was invented by the Greek scientist Archimedes, though the year is not known.
