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

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.

Rod, Stationary Thin Wall Barrel, Top Cup Anchor Pump

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

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

Rod, Stationary Heavy Wall Barrel, Bottom 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.

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

The upper open bonnet is standard on tubular pumps.The upper part is connected with the sucker rod string, the lower part is connected with the plunger, and the traveling valve is placed in it.Material selection and structural strength are the key factors in product design.In order to strengthen the protection of the valve hood, there are alloy lined valve hood designed for thermal production and high flushing oil Wells.There is a rubber lined valve cover designed for cold production and high stroke oil Wells.

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 fixed valve puller provides a device whereby a tubular oil pump can be used to carry out fixed valve maintenance operations by simply lifting the sucker rod string.

In this regard, Weima designed and developed a long plunger sand setting pump that can be used in wells with high sand content and interstitial wells with sand content of less than 3%.

The upper joint of the pump barrel is a standard part of the rod type oil pump.The upper part is connected with the stem guide sleeve and the lower part is connected with the pump barrel or lengthened.

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.

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.

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.

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

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 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.

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