The pump anchor designed and developed by Weima is used to let the rod pump seal in the tubing, not use the conventional seating any more. It can also be used in oil wells that must constantly adjust the pump setting depth of rod pump as the supply level changes to improve production efficiency.

The large diameter pump designed and developed by Weima is to design the oversized pump for a given casing size well. The outer diameter of the plunger shall be larger than the inner hole of the tubing.

The leather bowl support connector is connected to the tubing pump hanger design position. The length is going to be 6 in length. Up to 14 inches.

Standard part of a rod type pump used to connect the plunger to the rod string.

Double Acting Pump designed and developed by Weima is used for well with high reservoir pressure and sufficient liquid supply, especially those where conventional pumps cannot meet the displacement requirements.

The Double Sealed Rod Pump designed and developed by Weima applies the combination of mechanical seal and cup seal .

The hydraulic feedback pump designed by our company can exploit crude oil with viscosity ＞ 4000mpa*s.

Hydraulic station produces hydraulic oil with high pressure, drive the hydraulic cylinder operation through the hydraulic pipe line

Double Acting Pump is used for well with high reservoir pressure and sufficient liquid supply, especially those where conventional pumps cannot meet the displacement requirements.

The systems design, material composition and metallurgical processing have been patented and proven in the USA, Canada, Mexico, China and other countries in preventing and removing Corrosion, Scale, Paraffin, Asphaltenes.

The two-stage anti-gas rod pump designed and developed by Weima adopts a slender upper plunger connect with a larger diameter lower plunger in series to divide the lower pump barrel into upper and lower two working chambers.

The ground device has a simple structure and is easy to install, and can be directly connected with the wellhead casing four-way, and covers small area.
