Parameters

Single 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 agricultural machinery for transporting grain and other solids.
