Hebei Jerry Series PCP Advantages
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. Installation cost is minimal : The complete system can be installed by the service rig crew.
Low transportation costs : The complete system can be delivered in a pick-up truck.
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.
Efficiency: PCP systems are simple in structure ,have very few moving parts, low hydraulic losses and high efficiency in performance. The overall efficiency is normally between 40% and 70%; compared to 30% efficiency for plunger pumping units and 35%for electrical submerged centrifugal pumps. Typical volumetric efficiency of a "KeLian" down-hole pump system is 75%-95%.
