The PCP pump has a substantial history. It was invented and engineered in the late 1920’s by the Frenchman Rene Moineau.
Moineau set out to design a rotary compressor and in the process developed a new rotary mechanism to be employed for the utilization of variations in the pressure of a fluid, which he called “capsulism”. His purpose was to make it doable 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 the years, other small pump companies have produced spin-offs of the Moineau principle.
The Moineau concept has been put to work in many industries in a broad variety of applications since its licensing. It has been used as a pump 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 utilized 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 the function of the progressing cavity pump. The device was then being moved by fluid instead of pumping fluid. With the pump elements being driven by drilling mud or other fluids, it established itself as the primary mover for drill motors. The Moineau principle is presently being extensively employed in the petroleum drilling industry.
Then in the early 1980 s, the progressive cavity pump was put to work 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 PCP pump producer to market the pump as an option to ordinary lift methods and to establish a new market for the PCP pump. Since the mid-1980’s, other manufacturers have come 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 parts 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 broadly employed 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 great number of benefits over traditional lift equipment, of which the most important is lowering the cost per barrel lifted.
A progressive cavity pump also can function as a motor when fluid is pumped through the interior. Applications include well drilling.
Progressive cavity pumps are also frequently referred to by the specific producer or product names. It is not uncommon to have people refer to them as Moineau pump, Mono pump, Twister pump etc. The Twister PCP pump is a modern pump produced by Canam Pipe & supply.
