A progressive cavity pump is a positive displacement pump designed for handling a wide range of fluids, including highly viscous, abrasive, or shear-sensitive materials. It is widely used in industries such as wastewater treatment, oil and gas, food and beverage, and chemical processing due to its versatility and efficiency. The pump operates using a helical rotor that rotates inside a helical stator. As the rotor turns, cavities are formed between the rotor and stator, moving the fluid smoothly

Downhole Progressive Cavity Pump: A downhole progressive cavity pump connects the stator and the rotor of the pump to the end of the tube and sucker rod. The ground drive equipment then rotates the rotor through use of the sucker rod, thereby lifting underground liquid to the surface. This cavity pump is often used lift crude oil under 8000mPa.s, making it useful for most thick oil wells, such as high sand wells, high gas wells, offshore oil field cluster well groups, horizontal wells and more.
