The progressive cavity pump (PCP) is a positive displacement pump, using an eccentrally rotating single-helical rotor, turbing inside a stator. The rotor is usually constructed of a high-strenght steel rod, typicallydouble-chrome plated. The stator is a resilient elastomer in a double-helical configuration molded inside a steel casting.

Progressive cavity pumping systems can be used for lifting heavy oil at a variable flow rate. Solids and gas free production present minimal problems. They can be installed in deviated and horizontal wells. With its ability to move large volumes of water, the progressing cavity pump is also used for coal bed methane, dewatering, and water source wells. The PCP reduces overall operating costs by increasing operating efficiency while reducing energy requirements. The major disadvantages of Progressive Cavity Pumps PCP’s include short operating life (2-5 years) and high cost.
