A '''screw pump''' is a positive displacement pump that use one or several screws to move fluids or solids along the screw(s) axis. In its simplest form (the Archimedes' screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw's spindle. This ancient construction is still used in many low-tech applications, such as irrigation systems and in agriculturural machinery for transporting grain and other solids. | A '''screw pump''' is a positive displacement pump that use one or several screws to move fluids or solids along the screw(s) axis.
