Hebei Jerry Pump Co., Ltd. A PCP experts
Hebei Jerry Pump Co., Ltd. ( Original Yutian Kelian Industrial Co., Ltd.)                                                                                                                                                                 Today, PCM MOINEAU OILFIELD Division offers the largest range of progressing cavity oilwell pumps. PCM produces its own elastomers, and it has the expertise and facilities to continuously research and develop the products of tomorrow's oilfield requirements.
For many years, PCM has operated and maintained a sound quality control policy. Our ISO 9001 standard remains a guarantee of reliability and quality.
PCP  PRINCIPLE
A PCP consists of  a single helical rotor which rotates inside a double internal helical stator. The rotor is precisely machined from high strength steel ; the stator is molded of resilient elastomer. This makes the PC Pump the best pump for viscous fluids.
Completion : For oil production, the stator is fixed to the tubing and the rotor is attached to a sucker rod string. The pump is driven by rotation of the sucker rod string.
Large particle handling : The rotors are plated with a hard material to resist abrasion. Abrasive particles which are caught between the rotor and the stator are pressed into the elastic wall of the stator and then expelled into the next cavity when the rotor has passed.
Flow rate proportional to pump speed : As the PCP is a volumetric pump, the flow rate depends only on the rotor speed. Therefore the pump can be exactly matched to the well inflow rate for optimum production.
PCP Benefits
When compared to other artificial lift methods the PCP pump has many benefits for the user.
Lower capital costs : The lack of expensive foundations, the simple construction and the compact surface drive unit minimises start-up costs or allows more pumps to be installed (and so more oil recovered) for the same capital outlay.
Lower running costs : In most applications, typically a PC pump has a significantly higher overall mechanical efficiency than that available from alternative artificial lift methods such as Electric Submersible Centrifugal Pumps or Rod Pumps. The unit cost of fluid recovered is therefore reduced.
Reliability : The simple construction has no standing or travelling valves to block and only one moving part downhole. The pump handles gas and solids without blocking and is more resistant to abrasive wear.
More environmentally acceptable : The low unobtrusive profile of the quiet running surface drivehead makes the PC pump more acceptable in environmentally sensitive areas.
Low transportation costs : The complete system can be delivered in a pick-up truck.
Installation cost is minimal : The complete system can be installed by the service rig crew.
Absence of pulsations : in the formation near the bore hole will generate less sand production from unconsolidated sand reservoirs. Constant flow production makes instrumentation easier.
Constant stress : on rod string with minimal stress fluctuation decreases the risk of fatigue failure and rod fall.
Sand is handled efficiently due to the resilience of the stator material and the pumping mechanism.
Gas presence will not gas lock the pump.
Positive displacement rate is controlled by speed and is not a function of pressure, although pressure affects efficiency.
Wide production range for each model (3 : 1 range in production rates). This range can be achieved without any change of equipment, using a Variable Speed Drive.
Operating Safety : The compact drive systems can easily be caged or set bellow grade, out of the reach of people and animals, for maximum operating safety. All moving parts are enclosed in metal guards or housings, and the drive heads are equipped with anti back spin devices to protect maintenance personnel during operation.
Long Life : Pumping systems are built to last. All above-ground moving mechanical components are suspended in place by heavy-duty lubricated bearings, ensuring smooth vibration-free performance.
Easy adjustment : Belt drive mechanisms or hydraulic controls make it easy to change the speed of PC pumps for varying well production rates. Variable speed devices and gear reducers can be installed to make speed adjustments easier and to extend the range of pumping speeds.
Simple maintenance : PCP systems are easy to maintain in the field. The surface drivehead contains only one set of lubricated bearings and other easily maintained components that do not require special tools or procedures. The drivehead packing is easily adjusted for extended packing and drive shaft life. Only one moving part down hole for reduced maintenance and workovers.
