rod pump-manufacture,factory,supplier from China

Rod, Stationary Heavy 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.

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.

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

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

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

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 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.

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

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

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.

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.

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.

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

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

Rod, Stationary Thin Wall Barrel, Top Cup Anchor Pump

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.
