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

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:
