Downhole Tools-manufacture,factory,supplier from China

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

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.

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 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.

Stem guide sleeves are standard on rod pumps.Used for righting valve stem.

Rod, Stationary Thin Wall Barrel, Top Mechanical Anchor Pump

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 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.

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%.

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 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 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.

Rod, Stationary Heavy Wall Barrel, Top Mechanical 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.

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