Sucker Rod Pumps
A sucker rod pump is a positive-displacement downhole pump driven by a surface pumping unit through a string of sucker rods. It is the most widely used artificial lift method for onshore oil production worldwide, and the dominant lift technology in Azerbaijan’s mature oilfields.
Proxima supplies API-grade sucker rod pumps through ChampionX — one of the largest rod lift manufacturers in the industry, operating the Harbison-Fischer®, Norris, UPCO, and Alberta Oil Tool brands.
How a Sucker Rod Pump Works
The surface pumping unit (beam pump or pumping jack) drives a polished rod up and down. The polished rod connects to a sucker rod string that runs to the downhole pump. On the upstroke, the travelling valve closes and the standing valve opens, drawing fluid into the pump barrel. On the downstroke, the standing valve closes and the travelling valve opens, pushing fluid up the tubing to surface.
The pump is sized to match the well’s inflow performance, fluid properties, and depth.
Applications
Sucker rod pumps perform across a wide range of production conditions:
- Mature oilfields with moderate-to-low production rates
- Wells with high gas-oil ratios requiring gas-tolerant pump designs
- High-sand and abrasive environments
- Corrosive well fluids (H₂S, CO₂, brine)
- Deviated and directional wells
- Low bottomhole pressure wells requiring maximum drawdown
Product Range
Proxima supplies the full Harbison-Fischer® sucker rod pump portfolio, covering insert pumps, tubing pumps, and specialty pumps engineered for challenging downhole conditions.
Insert Pumps
Insert pumps are run inside the production tubing on the sucker rod string and retrieved without pulling the tubing. They are the standard choice for most onshore wells.
Available in sizes from 1¼” to 2¾” plunger diameter. All pumps conform to API 11AX dimensions.
Tubing Pumps
Tubing pumps offer larger bore diameters for higher production rates. The barrel is made up as part of the tubing string; retrieval requires pulling the tubing. Used where maximum fluid throughput is required.
Specialty Pumps for Challenging Conditions
| Model | Application | Key Feature |
|---|---|---|
| — | — | — |
| Sand-Pro+™ | High sand cut, abrasive solids | Electroformed screen restrains solids from plunger leading edge |
| Pampa™ | Severe gas and solids combined | Increased compression ratio, larger plunger/barrel wear areas |
| Variable Slippage™ | Gassy wells | Pressure equalization before top of upstroke — prevents gas lock |
| QuadPro™ plunger | Abrasive and corrosive service | Hard coating with improved sand tolerance and corrosion resistance |
All specialty pumps are available in corrosion-resistant materials and coatings. API-compliant components allow interchangeability with standard field inventory.

Frequently Asked Questions
Q: What is the difference between an insert pump and a tubing pump?
An insert pump is run inside the tubing on the rod string and can be pulled for maintenance without removing the tubing. A tubing pump has a larger bore for higher rates but requires a full tubing pull to retrieve. The choice depends on production rate, well depth, and workover cost.
Q: Which pump is best for a high-sand well?
The Harbison-Fischer® Sand-Pro+™ pump is designed specifically for high-sand and abrasive conditions. Its electroformed screen prevents solids from entering the plunger-barrel interface, extending run life significantly compared to a standard pump.
Q: Can Proxima supply pumps for sour service (H₂S)?
Yes. Harbison-Fischer® pumps are available in NACE-compliant materials for sour service. Specify H₂S partial pressure and total well conditions when requesting a quote.
Q: How do I select the right pump size?
Pump sizing depends on target production rate, fluid gravity, pump depth, and sucker rod string design. Proxima’s application engineers perform sizing calculations using well data you provide. Contact us with your well parameters for a recommendation.
Q: Does Proxima stock sucker rod pumps in Baku?
Yes, we maintain local inventory of standard pump sizes. Specialty configurations and larger sizes are sourced on order. Lead times depend on configuration — contact us for availability.
