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 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.

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

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

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

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.

Rod, Stationary Heavy Wall Barrel, Top Mechanical Anchor 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 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 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.

Rod, Stationary Heavy Wall Barrel, Bottom Mechanical Anchor Pump

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

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