The Progressing Cavity Pump, also known as the mono pump, is a straightforward, strong device that excels in pumping slurries and sludges, making it ideal for use in sewage treatment, oil and gas exploration, and other applications. These are actually a more contemporary form of the Archimedes screw, which has been used for millennia to transport liquids along by rotating a helical thread. Such simplicity is highly alluring for the nuclear business, where maintenance must be as efficient as feasible.
Positive displacement pumps like the Progressing Cavity Pump (PCP) use eccentrically rotating single-helical rotors that spin inside of stators. A high-strength steel rod that is often double-chrome plated is used to make the rotor. The stator is made of a durable elastomer that has been moulded inside of a steel casing to form two helices.
