A progressive cavity pump is a type of positive displacement pump that uses a rotating helical screw-shaped rotor to move fluids through a fixed stator. As the rotor turns, it traps a fixed volume of fluid and moves it through the stator and out of the pump. Progressive cavity pumps are capable of handling a wide range of fluids, including those that are viscous, abrasive, or contain solids. They are often used in applications where the flow rate needs to be accurately controlled, such as in metering pumps or in the food (organic soups) and beverage industry. They are also used in oil and gas production, sewage treatment, and other industrial processes.
