Main Specifications
Standards | API Spec 11AX |
Types | API insert pumps, API tubing pumps |
Manufactured strictly to API Spec 11AX, Sovonex™ tubing and rod pumps are well suited for a wide range of pumping applications. Each pump is machined with an extra small clearance between the plunger and the barrel to provide maximum performance and long service life.

We manufacture all subsurface pumps covered by API Spec 11AX, including all barrel and plunger materials and surface finishes.
This is why Sovonex™ 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, Sovonex™ 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, and are best used in combination with our API sucker rods.
Sucker rod pumps, also known as sucker rod pumps or insert pumps, are classified by the letter R.
Heavy-wall barrel subsurface pumps for use at greater depths or under harsh pumping conditions, such as scale formation.
RH insert pump with stationary barrel and top anchor seating.
Available with either a cup seating assembly (RHAC) or metal seal (RHAM).
Field of application
RH insert pump with stationary barrel and bottom anchor seating.
Available with either a cup seating assembly (RHBC) or metal seal (RHBM).
Field of application
RH insert pump with travelling barrel and bottom anchor seating.
Available with either a cup seating assembly (RHTC) or metal seal (RHTM).
Field of application
Thin-wall barrel sucker rod pumps for use in wells of moderate depth and large volume wells.
RW insert pump with stationary barrel and top anchor seating.
Available with either a cup seating assembly (RWAC) or metal seal (RWAM).
Field of application
RW sucker rod pump with stationary barrel and bottom anchor seating.
Available with either a cup seating assembly (RWBC) or metal seal (RWBM).
Field of application
RW insert pump with travelling barrel and bottom anchor seating.
Available with either a cup seating assembly (RWTC) or metal seal (RWTM).
Field of application
Rod pumps with heavy wall, internally threaded barrel.
RX rod pump with static barrel and bottom anchor seating.
Available with either a cup seating assembly (RXBC) or metal seal (RXBM).
Field of application
Tubing pumps are classified by the letter T.
TH is the only tubing pump configuration specified by API Spec 11AX.
Equipped with a heavy wall barrel and a bottom hold-down (anchor), these pumps are suitable for wells with harsh pumping conditions and were scale formation is a problem.
Available with either a cup seating assembly (THC) or metal seal (THM).
