Progressing Cavity Pump (PCP) Systems
PCP Pump Systems Impress With High Efficiency
In addition to pumping at a constant pressure and flow rate, progressing cavity pump (PCP) systems can work almost without pulsation and shear force. Therefore, emulsion effects in the oil-water mixture are avoided. This makes separating the oil-water mixtures at the surface much more accessible. However, the key advantage of the progressing cavity pump system is its extremely high efficiency. This makes even pumping under the most challenging conditions effective again.
For example, the volumetric efficiency of a borehole progressing cavity pump is between 75 and 90 percent, which is significantly higher than that of conventional pumps. Electric submersible pumps or the frequently used horsehead pumps sometimes only have an efficiency of less than 35 percent.
