Progressing Cavity Pump - KUDU PCP | SLB

PCP Systems

Efficiently handle high-viscosity fluid and high sand cut

Fluid rates up to 2,830 bbl/d [450 m3/d]
High-temperature rating up to 660 degF [350 degC]
Adjustable rpm to match reservoir inflow rates

Efficiently handle solids and high-viscosity fluids

KUDU PCPs efficiently handle solids and high-viscosity fluids with superior engineering that delivers a consistent head capacity.

The KUDU PCP delivers a constant flow, proportional to the size of the cavity and the rotational speed of the rotor. A hydraulic or electric drive system at the surface rotates the rod string, which causes the rotor to spin within the fixed stator, resulting in fluid production at the surface.

Match your well conditions with the best-suited PCP solution

Maximize production while leaving a minimal footprint with progressing cavity pump (PCP) systems. The KUDU PCP is a positive displacement pump with a range of models, elastomers, and rotor options to meet your specific application. These PCPs are designed to deliver a consistent head capacity with superior handling of solids and high-viscosity fluids.

KUDU Elastomers

KUDU’s elastomers provide significant improvements in bond strength, tear strength, abrasion resistance, gas and water resistance, and temperature ratings. This has expanded the use of PCPs in a variety of environments. Elastomers are primarily made up of nitrile, a copolymer of butadiene, and acrylonitrile. In addition, KUDU offers a fluorocarbon elastomer for greater resistance to aromatics and H2S.

KUDU Rotors

The KUDU PCP features a single helical rotor that rotates inside a double internal helical elastomer-lined stator. The stator is run into the well on the end of the production tubing while the rotor is connected to a rodstring. The PCP lifts fluid by transferring it from the intake at the bottom of the pump to the discharge at the top through a sequence of small, discrete cavities that form as the rotor turns eccentrically within the stator.

The PCP delivers a constant flow, proportional to the size of the cavity and the rotational speed of the rotor. A hydraulic or electric drive system at the surface rotates the rodstring, which causes the rotor to spin within the fixed stator, resulting in fluid production at the surface.
