Progressive cavity pumps (also referred to as single screw pumps) use a single-threaded screw that rotates within a double-threaded rubber shaft to move liquid through a pump while building pressure to force liquid throughout the process. Progressive cavity pumps can manage complex liquids that contain solids. This makes them an option in a variety of industrial and wastewater treatments. Smaller progressive cavity pumps can be used in oil lubrication systems and elevators. Larger versions of progress cavity pumps are used to pump sewage, slurries, and other viscous chemicals. They can also be used where sterile environments are maintained, including food processing and pharmaceuticals.
