The stator is run into the well on the bottom of the production tubing, while the rotor is connected to the end of the rodstring. The rotor turns eccentrically in the stator, forming cavities from the intake at the bottom of the pump to the discharge at the top of the pump. The PCP delivers a constant flow that is proportional to the size of the cavity and rotational speed of the rotor. Rotation of the rodstring at surface is powered by a hydraulic or electric drive system, which causes the rotor to spin within the fixed stator, resulting in fluid production at surface. Schlumberger also offers a high-temperature package, featuring an all-metal PCP capable of withstanding the extreme downhole conditions of thermal recovery. Elastomers Proprietary elastomers provide significant improvements in bond strength, tear strength, abrasion resistance, gas and water resistance, and temperature ratings, expanding the use of PCPs to additional environments. Elastomers are primarily made up of nitrile, a copolymer of butadiene, and acrylonitrile. In addition, a fluorocarbon elastomer for greater resistance to aromatics and H 2 S is available. Rotors The rotor is the moving component of a PCP and is held from the surface by the drive string, which is typically a conventional or continuous sucker rod. The amount or degree of interference fit is critical to the efficiency and life expectancy of the pump. Interference fit is changed by choosing a different rotor minor diameter.

PCP Well Manager EVEN WALL PCP EVEN WALL uniform-elastomer PCP provides a uniform elastomer thickness, resulting in an even temperature distribution under swell conditions. Since the elastomer swells evenly, it enables a more consistent fit between the rotor and stator, ultimately improving pump performance. KUDU Tough Coat Rotor Coating KUDU Tough Coat rotor coating is a spray metal coating applied to PCP rotors. Rotors with this coating have significantly improved corrosion resistance compared to a typical chrome rotors, resulting in longer rotor life, increased production efficiency, and lower operating costs. KUDU PCP ISO compliance ensures manufacturers adhere to a strict process to ensure products are of high quality and meet specification requirements.
