Sucker Rod Pump

1. Our forced valve rod pump adopts mechanical forced valve design, the response speed of the traveling valve is increased by 80%, gas interference is effectively blocked, and the gas lock rate is reduced by 90%. 2. The forced valve rod pump is suitable for heavy oil wells with viscosity >10000 mPa·s, with a theoretical displacement of up to 800m³/d (83mm pump diameter), and an average daily increase of 35%-50%. 3. The stroke range of the forced valve rod pump is 2.0-6.0 meters, and the pump barrel length can be adjusted to 7.5 meters, which can easily cope with ultra-deep well conditions of 2000-5000 meters.

The​‍​‌‍​‍‌​‍​‌‍​‍‌ annulus sucker rod pump, specially designed for heavy oil wells with high viscosity and sand content, can greatly stabilize pumping and minimize blockages during thermal recovery. This kind of pump is most frequently used in 7” and 5 1/2” cased wells. It is a good choice for distributors and contractors of oilfield projects who want reliable and easy-to-maintain pumping ​‍​‌‍​‍‌​‍​‌‍​‍‌solutions.

High-performance sand control sucker rod pump designed for sandy oil wells. Improve pump life, reduce wear, and maintain stable oil production in sand-producing reservoirs.

Specifically designed for heavy oil and high gas-cut wells. The mechanical forced-opening mechanism ensures the valve opens/closes on every stroke, regardless of fluid viscosity.

1. RWT API insert pumps can be used with the pumping rod column, which does not affect the oil pipe column, greatly saving operating time and cost.​ 2. This RWT API insert pumps is especially suitable for oil wells with small displacement pumping and deep pumping, which can meet a variety of working conditions.​ 3. The unique design of RWT API insert pumps reduces the risk of sand particles and other sedimentation stuck in the pump and ensures the stable operation of the pump.​

1. Our inclined well sucker rod pump adopts spring forced seat sealing technology, so our inclined well sucker rod pump solves the industry problem that the valve ball of traditional oil well pumps cannot return to its original position by gravity in inclined wells and horizontal wells. 2. Unlike ordinary oil well pumps that can only be used in vertical wells, our inclined well sucker rod pump can maintain stable operation at any angle of 0-90°. 3. The modular design of the inclined well sucker rod pump allows for quick replacement of pump diameter components (only 2 hours), and the same platform can adapt to different production capacity requirements of 32-95mm. 4. The special flow channel design of the inclined well sucker rod pump enables the viscosity adaptation range to reach 50-5000mPa·s.

1.Large displacement tubing pump has dual working state switching function. Large displacement tubing pump can operate in two different working modes through the switch connector between the upper plunger and the lower plunger. 2.Due to this dual working state, the large displacement tubing pump can still maintain efficient operation under the condition of temperature and viscosity changes. When the wellhead temperature drops and the viscosity increases, the switch connector switches to the "open" position and continues to work efficiently. 3.When the large displacement tubing pump switch connector is in the "off" position, the displacement of the pump is the same as the size of the upper pump. When the large displacement tubing pump connector is switched to the "on" position, the displacement matches the oil inlet return pump, reducing energy loss.

1. Chrome brass barrel for oil pump adopts double anti-corrosion structure of brass base and hard chrome plating, which is resistant to strong acid, strong alkali and seawater corrosion. The service life of chrome brass barrel for oil pump is more than 2 times that of ordinary stainless steel barrels for sucker rod pumps. 2. Chrome brass barrel for oil pump is hygienic and safe, perfectly matches the plunger, and effectively prevents medium leakage. 3. Chrome brass barrel for oil pump has passed ISO9001 and API11AX certification, and the whole process from raw materials to finished products is tested. The performance of each chrome brass barrel for oil pump is stable and reliable.

1.Three-acting tandem oil well pump is suitable for oil wells with sufficient liquid supply. 2.Three-acting tandem oil well pump can suck and discharge liquid during the up and down strokes. Three-acting tandem oil well pump has the characteristics of small pump diameter, large displacement, and deep pumping. 3.The special structure of three-acting tandem oil well pump enables three oil suction and three oil discharge actions to be completed in one reciprocating stroke, which can realize multi-layer oil wells.

1. Upward stroke: When the plunger of the heavy oil pump with hydraulic feedback moves upward, the upper liquid enters the lower chamber through a specially designed feedback channel to form hydraulic energy storage. 2. Downward stroke: The stored hydraulic energy is converted into auxiliary thrust (actually measured up to 2-5kN), and the heavy oil pump with hydraulic feedback can effectively overcome the resistance of heavy oil. 3. Pressure balance design: The heavy oil pump with hydraulic feedback uses our original two-way flow channel structure to balance the pressure inside and outside the pump in real time to avoid air lock and sand jam.
