Customized Sucker Rod Pumping Unit for Oilfield Operations Core Component Pump

API 11AX sucker rod pump

Description of oil pump

We can provide API pump and special pump

API pump: RHAC, RHBM, RHAM , RTH(B)C, TH(B)M, RWBM, RWBC, RWAM, RWAC R, RHBM-A, RHBC R

We manufacture all subsurface pumps covered by API Spec 11AX, including all barrel and plunger materials and surface finishes.
This is why our sucker rod pumps can be furnished with the components most suitable for your field of application and pumping operations can easily be extended to corrosive environments.
To achieve maximum performance,API subsurface pumps are machined with extra small clearance between the plunger and the inside wall of the barrel.

Our sucker rod pumps are categorized according to the API 11AX pump designation.
API-RHAC, Rod, Stationary Heavy Wall Barrel, Cup Top Anchor Pump
API-RHBM, Rod, Stationary Heavy Wall Barrel, Mechanical Bottom Anchor Pump
API-RHBC, Rod, Stationary Heavy Wall Barrel, Cup Bottom Anchor Pump
API-RWAM, Rod, Stationary Thin Wall Barrel, Mechanical Top Anchor Pump
API-RWAC, Rod, Stationary Thin Wall Barrel, Cup Top Anchor Pump
API-RWBM, Rod, Stationary Thin Wall Barrel, Mechanical Bottom Anchor Pump

Specification table of API sucker rod pumps:

The operating principle of tubing pumps involves the pump barrel assembly being securely attached to a tubing string. The plunger assembly is connected to the sucker rod string and moves up and down in a reciprocating motion, facilitating the production process. One of the main advantages of tubing pumps is that they allow for efficient problem-solving during oil production. When issues arise with the traveling valve or fixed valve, the valve side can be addressed by utilizing the sucker rod, piston, and extractor. This eliminates the need to remove the entire pump and tubing string from the well, reducing labor intensity and operational costs.

Main parts process and material:
Pump barrel: plain carbon steel plating (A1), ordinary carbon steel carbonitriding (B1), ordinary carbon steel carburizing (B2), low alloy steel nitride (B5).
