Shandong Weima API Tubing Pump Series

We manufacture all subsurface pumps covered by API Spec *1AX, including all barrel and plunger materials and surface finishes.

This is why Weima tubing 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, Weima  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 *1AX pump designation.

API Tubing Pumps

Tubing pumps are classified by the letter T.

TH pumps

TH is the only tubing pump configuration specified by API Spec *1AX.

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).

Field of application

• Suitable for very deep wells if connected to a sufficiently robust sucker rod string.
• Large volume wells where the larger production capacity outweighs the higher service costs of the pump.
• Sandy wells

Notes: 1. Type of barrel: chrome plated or carbonitrided surface

           2. Type of plunger: metal spray or chrome plated surface

           3. Valve ball and seat materials: stainless steel and tungsten carbide
