Pumping Units & Pumps

Beam pumping units and downhole sucker rod pumps are the most widely used artificial lifting equipment for onshore oilfields, designed to extract crude oil from low-pressure, low-yield, and depleted oil reservoirs. As core surface and downhole matching equipment, the beam pump serves as the surface power transmission system, while the downhole pump acts as the underground liquid lifting component, forming a complete and reliable oil recovery system. This integrated pumping system is suitable for conventional oil wells, heavy oil wells, deviated wells, and water-cut increasing oil wells, featur...

1. Product Overview

Beam Pumping Units and downhole Sucker Rod pumps are the most widely used artificial lifting equipment for onshore oilfields, designed to extract crude oil from low-pressure, low-yield, and depleted oil reservoirs. As core surface and downhole matching equipment, the beam pump serves as the surface power transmission system, while the downhole pump acts as the underground liquid lifting component, forming a complete and reliable oil recovery system. This integrated pumping system is suitable for conventional oil wells, heavy oil wells, deviated wells, and water-cut increasing oil wells, featuring simple structure, stable operation, low failure rate, and extremely low daily maintenance costs compared with screw pumps and electric submersible pumps.

The beam pumping unit converts the rotary motion of the motor into the up-and-down reciprocating linear motion of the walking beam, driving the Polished Rod and sucker rod string to move the plunger inside the downhole pump. Through the opening and closing of traveling valves and standing valves, the pump completes oil suction and oil discharge circulation, continuously lifting crude oil from the reservoir to the ground pipeline. The whole set of equipment adapts to harsh working conditions such as sand-containing crude oil, high water cut, and low-temperature and high-temperature oilfield environments. It supports long-term 24-hour continuous operation without frequent shutdowns, greatly improving the stable production capacity of marginal and old oilfields.

All key load-bearing parts such as crank, connecting rod, walking beam, and horse head adopt integral cast steel and thickened welded steel structures, with overall anti-rust and anti-corrosion treatment to adapt to outdoor open-air operation for many years. The downhole pump barrel, plunger, and valve assembly are made of high-strength wear-resistant alloy materials, effectively resisting sand abrasion and liquid corrosion. With strong compatibility and wide adaptability, the beam pump and downhole pump combination has become the standard artificial lifting solution for onshore oilfield development worldwide.

FAQ

Q1: What are the advantages of Beam Pumping Units compared with other lifting equipment?

A1: Beam pumping units have simple mechanical structure, extremely low failure rate, convenient maintenance, and low operating cost. They can adapt to sand-containing, high water-cut, and low-yield old oil wells, and support long-term continuous outdoor operation. Compared with submersible pumps and screw pumps, beam pumps have longer service life and lower later maintenance investment.

Q2: Can you provide customized pumping units and downhole pumps?

A2: Yes. We can customize stroke length, load grade, pumping speed, and downhole pump bore size according to customer well depth, reservoir production, oil quality, and local climate conditions. We also support matching complete rod string, Polished Rod, and sealing accessories to provide one-stop supporting solutions.

Q3: What standards do your pumping equipment comply with?

A3: All beam pumping units are manufactured strictly according to API 11E standard, and all downhole pumps meet petroleum industry specification requirements. We can provide complete factory test reports, quality certificates, and third-party inspection documents for export customs clearance and project acceptance.

Q4: What is your delivery time?

A4: Standard models have sufficient stock and can be delivered quickly. For customized models, the production cycle is 15–25 working days according to the customization degree. We guarantee stable quality and on-time shipment for bulk orders.

Q5: Do you provide after-sales technical support?

A5: We provide professional product installation guidance, operation training, and long-term after-sales maintenance consulting. Spare parts support is available globally to ensure the stable and continuous operation of customer oilfield equipment.
