Shandong Weima API Insert Pump 

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

This is why Weima 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, Weima API sucker rod 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.
