The PCP pump has a substantial chronicles. It was invented and intended in the late 1920’s by the Frenchman Rene Moineau.
Moineau set out to make a rotary compressor and in the process developed a supplementary rotary mechanism to be utilised for the utilization of variations in the pressure of a shapeless, which he referred to as “capsulism”. His incline toward was to make it possible to use this capsulism in pumps, compressors, or motors.
In the in the future 1930’s, the Progressive Cavity Pump’s concept patent was licensed to three companies: PCM-Pompes of France, Mono Pumps Ltd. Of England, and Robbins & Myers, Inc. Of the United States. Over the years, go ahead little pump companies have produced spin-offs of the Moineau concept.

The Moineau principle has been utilized in many industries in a invincible variety of applications back its licensing. It has been utilised as a pump in in marginal note to every single one industry: chemical, coal, food, metal working, mining, paper, petroleum, textile, tobacco, and water and waste water treatment. In the petroleum industry, the PCP pump has been implemented as a surface transfer pump for sophisticated than 50 years.
In the mid- 1950’s, the taking into consideration cavity pump principle was applied to hydraulic motor applications by reversing the act-fighting of the progressing cavity pump. The machine was later creature moved by unstructured in place of pumping shapeless. With the pump elements creature driven by drilling mud or totaling fluids, it customary itself as the primary mover for drill motors. The Moineau principle is now bodily widely utilised in the petroleum drilling industry.
Then in the in further 1980’s, the far and wide ahead cavity pump was implemented as an pessimist lift method in the petroleum industry. Robbins & Meyers, Inc. Of the United States has to be endorsed taking into account physical the first to apply the Moineau principle to unnatural lift in the petroleum industry. They conventional itself as the first PCP pump producer to heavens around the pump as a another to everyday lift methods and to avow a adding marketplace for the PCP pump. Since the mid-1980’s, added manufacturers have come into this marketplace, expanding the right of admission of the product by the oil and gas industry.
The pump is applied to artificial lift by attaching the pump components to the tubing and rod string. The stator is manage upon the subside of the tubing, and the rotor is attached to the bottom of the rod string and landed in the stator. The rods and rotor are rotated through a wellhead aspiration assembly that is engineered to carry the weight of the rod and the nebulous column.
Currently, the PCP pump is visceral extensively used for lifting fluids from depths of 6,000 ft. And deeper in oil and gas wells. Progressive cavity pumps offers to the petroleum industry a pleasing number of advantages more than venerated lift equipment, of which the most significant is lowering the cost per barrel lifted.
