Downhole Pumps

Using the latest manufacturing and elastomer technologies, Weatherford rotors and stators are produced to exacting tolerances to provide superior pumping performance. Each combination of rotor and stator is selected and the fit tuned to match specific well fluids and downhole conditions. Available pump configurations include:

Conventional Pumps. Our conventional PCPs are the standard of the industry. Conventional stators use round tubing designed for easy running with most standard oilfield production tubing. A wide variety of pump displacements and lifts are available for various production-tubing sizes.

Slimhole Pumps. Reduced-OD pumps are available for use in small casing sizes and in thick-wall casing.

Insert Pumps. Insertable PCPs reduce downtime during the running and pulling phase by requiring removal of only the rods from the well, rather than the tubing string. Our patented Arrowhead™ technology reduces the pump assembly length by as much as one-half to two-thirds versus competing insert-pump designs.

Charge Pumps. Charge pumps can be installed below other PCPs to compress gas in foamy-, heavy-oil applications to increase pumping efficiency.

Coilable Pumps. Coilable pumps allow coiled tubing access past the suspended rotor and through the stator for ease of cleanout and flushby operations.

Uniform-Thickness Pumps. Weatherford’s uniform thickness stators provide improved heat dissipation to resist elastomer distortion and swelling caused by heat and chemicals. The stators also provide higher lift per stage of pump.
