Rod, Stationary Thin Wall Barrel, Top Cup Anchor Pump

The drawpipe is a standard part of the moving bobbin pump.Material selection is seamless steel tube, the surface can be chrome plated or other anticorrosive hardening treatment.

Rod, Stationary Heavy Wall Barrel, Bottom Mechanical Anchor Pump

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

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

The overall appearance of the motor is flat type, the internal stator is independent centralized winding mode

Rod, Stationary Heavy Wall Barrel, Top Mechanical Anchor Pump

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.

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

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.

The stem reducer joint is a standard part of the sucker rod pump and connects the upper stem of the plunger to the rod string.The connecting part with the valve stem is the key to the structure of the product. The more likely problem to occur is the breaking off of the connecting valve stem.Therefore, its material’s selection and structural strength’s design need to fully consider the product’s operating environment.

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.

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 linear motor carries out reciprocating movement under the control of the ground control cabinet, to drive the plunger of the sucker rod pump reciprocating, so as to complete the lifting well liquid to the ground via tubing.

Tubing pump with box end plunger, tap type puller, cup anchor standing valve

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

According to the characteristics of heavy oil wells, Weima uses the pressure of the tubing liquid column to assist the sucker rod to descend, and has designed several special henavy oil pumps.

Hydraulic drive oil production system includes: control cabinet, hydraulic control device, liquid transmission pipe, hydraulic drive propeller and plunger pump.

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.
