Screw Impeller

A screw pump is a positive-displacement (PD) 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.

The impeller provides efficient handling of a range of liquids, often highly abrasive or corrosive in nature.  It is ideal for Solids Handling, Pumping Viscous Sludges and Handling Delicate or Low Shear Products.
