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

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

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.

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

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.

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%.

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

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.

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.

Gas source upper the well only needs regular maintenance, which adopts intermittent operation, with a long service life.

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 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.

Seat plugs are standard on the plunger of a pump. For jacking traveling seat.

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.

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