Stop Cross-Flow: Prevent high-pressure layers from suppressing low-pressure zones. Water Cut Control: Selectively produce from oil-rich layers while isolating water-heavy zones. Cost Efficiency: Produce from two or more reservoirs simultaneously using a single string, reducing operational OPEX.
Our company's Separate production oil pump is a double-pump single-acting oil pump. The upper and lower pumps of the dual-channel oil well pump work at the same time. The upper pump uses the annular space formed by the difference in the diameters of the upper and lower plungers to work. The upper oil enters the space through the upper pump inlet valve and then is discharged through the upper pump outlet valve. The lower oil enters the lower pump barrel through the lower pump inlet valve, and then is discharged from the lower pump outlet valve, mixed with the upper oil and discharged from the ground together. The pump is suitable for the stratified production of oil wells. The structure of the dual-channel oil well pump is: the oil outlet valve, upper plunger, upper pump oil outlet valve, upper pump barrel, central pipe, upper pump oil inlet valve, lower pump oil outlet valve, lower pump barrel, lower pump oil outlet valve, and lower pump oil inlet valve work together.

Mechanical Integrity: Integrated with specialized packers for reliable zone isolation.
Anti-Interference Design: Unique valve configuration ensures independent fluid entry from targeted layers.
Corrosion-Resistant Options: Available in Spray-metal or Chrome-plated barrels for H2S/CO2 environments.
Founded over 20 years ago, DS Rod Pump (Dongsheng Oilfield) has established itself as a premier leader in the design and manufacturing of subsurface oil well pumps. Operating from a state-of-the-art 20,000-square-meter facility, we combine decades of field experience with advanced manufacturing to support the world's most demanding oilfield operations.
Scale & Production Capacity
With a dedicated team of 150+ skilled professionals, we maintain a high production intensity, delivering up to 3,000 sets of rod pumps per month. Our annual output value exceeds RMB 50 million, reflecting our stability and large-scale supply chain capability as a top-tier manufacturer.
"At DongSheng, we understand that subsurface pump failure translates directly into costly downtime and lost production. That’s why every Forced Opening Valve Insert Pump is manufactured to the strictest API 11AX and ISO 9001 standards.
To ensure flawless performance in your most challenging high-viscosity and gassy wells, each unit undergoes a comprehensive 100% vacuum testing and pressure integrity check before leaving our facility.

1. Separate layer production oil well pump is a long and precise piece of equipment. We will pay attention to stable lifting and lowering during loading and unloading, and take measures to prevent collision and falling to avoid damage. The oil production tool sucker pony rod will be protected with a cap or cotton cloth to support the sealing assembly during transportation to prevent damage to the sealing surface.
2. When we transport it by car, we will install the oil production tool sucker pony rod on the bracket and fix it. The pump rack should be placed steadily and avoid stacking as much as possible, and fix it to prevent it from falling during transportation.
3. When we transport it on site in the oil field, we will install the oil production tool sucker pony rod on a special horizontal bracket and transport it by a special vehicle. The distance between adjacent fulcrums on the bracket shall not exceed 1.5 meters. Before transporting the oil production tool sucker pony rod to the well site, we will insert the oil pump into a new oil pipe to prevent damage to the seal caused by collision.
"Custom Configuration for Your Reservoir"
