Rod driven PCP

Lower life cycle costs and operation simplicity remain the main reasons why operators select PCM PCP technology for artificial lift applications.

Benefits

There are many reasons to select progressing cavity pump (PCP) technology for your artificial lift applications. One major benefit is how simple our oil pumping systems are to operate. As PCP volumetric technology allows for easy adjustment according to rotation speed, production can be controlled easily. This also ensures that our pumps offer steady production, even at low submergence. PCP pumps offer lower life cycle costs than conventional artificial lift technologies such as ESP or SRP as well as the following advantages:

Temperature

Pumps with elastomer stators can perform at temperatures of up to 150°C and the PCM VulcainTM extends that limit up to an extraordinary 350°C.

Viscosity and solids handling

The PCP design is ideal for pumping viscous and abrasive fluids, meaning it’s perfect for use in cold heavy production with sands (CHOPS).

Low fluid emulsion

Thanks to a very low fluid shear rate, PCPs prevent emulsion that can cause high-pressure losses in the production flow and require chemical treatment for breakdown.

Steady production

The PCP volumetric system handles steadily well dynamics, viscosities or free gas content fluctuations.

Operation and installation

Our equipment is easy to install, maintain and operate because the PCP is a volumetric pump which delivers smooth operation with a non-pulsating flow.

CAPEX et OPEX

PCM’s equipment requires a low initial investment cost as well as low operational costs once up and running.

Energy savings and environment impact

Of all artificial lift pumps, PCPs have the best overall efficiency (up to 85%). It’s also possible to save between 10-50% of the total energy consumption, in addition to a reduced surface footprint. 

Performances

Sealed lenticular cavities are created when a single helix rotor, precision machined from high strength steel, is inserted into a double helix elastomer stator (or an all-metal stator in the Vulcain™ pump). When the rotor turns, the cavities progress through the pump along the length of the rotor, gently carrying liquid, gas or solids from the intake to the outtake. This makes a progressive cavity pump your best choice for viscous and abrasive fluids.

The volume of the sealed cavities determines the capacity of the PCP as well as its nominal flow rate for any given speed and load. As soon as the pump is loaded, there is some internal leakage between cavities which provides lubrication between the rotor and stator.

One of the main rules of PCP design is to find the right balance between the seal of the cavities for optimal performance and the amount of leakage needed for lubrication which has an impact on run life. PCM achieves this balance by selecting the best elastomer and rotor size for your application.
