The PCP pump has a long history. It was invented

Moineau set out to design a rotary compressor and in the process developed a new rotary mechanism to be utilised for the utilization of variations in the pressure of a fluid, which he referred to as 'capsulism'. His purpose was to make it achievable to use this capsulism in pumps, compressors, or motors. In the early 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 time, other smaller companies have manufactured spin-offs of the Moineau principle. The Moineau concept has been implimented in many industries in a broad variety of applications since its licensing. It has been utilised in just about every 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 used as a surface transfer pump for over 50 years. In the mid- 1950's, the progressive cavity pump principle was applied to hydraulic motor applications by reversing its function. The mechanism was then being moved by fluid in place of pumping fluid. With the pump components being driven by drilling mud or other fluids, it established itself as the primary mover for drill motors. The Moineau concept is at present being extensively used in the petroleum drilling industry. Then in the early 1980's, the progressive cavity pump was used as an artificial lift method in the petroleum industry. Robbins & Meyers, Inc. Of the United States has to be credited with being the first to apply the Moineau concept to artificial lift in the petroleum industry. They turned into the first manufacturer to market the PCP pump as an option to traditional lift methods and to establish a new marketplace for it. Since the mid-1980's, other producers have entered into this marketplace, enlarging the acceptance 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 run on the end 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 drive assembly that is designed to carry the weight of the rod and the fluid column. Currently, the PCP pump is being widely employed for lifting fluids from depths of 6,000 ft. And deeper in oil and gas wells. It gives to the petroleum industry a great number of benefits over traditional lift equipment, of which the most important is lowering the cost per barrel lifted. It can also can behave as a motor when fluid is pumped through the inside. Applications include well drilling. Progressive cavity pumps are also often referred to by the specific producer or product names. It is not unusual to have people refer to them as Moineau pump, Mono pump, Twister pump etc. The Twister PCP pump is a modern pump manufactured by Canam Pipe & supply.
