Progressing Cavity Pumps (PCP) offer a versatile, high efficiency, and low cost
artificial lift method for heavy,
medium, and light crude oil. The simple geometry of this type of pump is composed mainly
of a metal rotor and a
stator elastomeric that give great advantages to the system.
Positive displacement pumps are characterized by a constant flow rate even while the discharge pressure varies, which is one of the most important advantages of this type of pump. Additionally, with the progressive cavity technology, fluids containing water, sand, and paraffin can be pumped.
Unlike other systems, the PCP establishes a constant torque inside the oil well; it produces less friction, significantly reducing energy consumption reaching up to 50% in energy savings compared with other methods.
