Products
API 11AX rod pumps, speciality designs for sand and gas, spare parts, and a full-service pump configurator — manufactured at our Brazi, Romania facility.
Reciprocating rod pumps are the most widely used artificial lift method in the world — a mature, API-standardized technology that works across an enormous range of well conditions. ELSI manufactures a complete range of rod pumps to API 11AX specifications. From conventional insert and tubing pumps to speciality designs for sand, gas, and harsh environments — everything ships from our Brazi facility with fast turnaround and full traceability.

Rod pumping isn't glamorous — but it's the most reliable, best-understood, most widely-supported lift method in oil and gas. For the majority of wells, it's also the most economical.
Industry-standard technology with decades of field history, mature service infrastructure, and deep operator expertise.
Works across vertical, slightly deviated, and many horizontal wells — from marginal producers to high-rate developments.
Lower capex than ESP, simpler surface equipment than gas lift, easy field maintenance with standard workover crews.
Interchangeable parts, compatible accessories, and a standardized spec means predictable performance and supply.
The choice depends on what your well produces. Standard conditions call for standard pumps. Sand, high gas, or both together need engineered solutions.
Standardized rod pumps to API 11AX specification. The right call for most conventional wells — predictable performance, interchangeable parts, widest spare availability.
Engineered answers to conditions that disable conventional pumps. Sand, high GLR, or both — each design solves a specific mechanical failure mode.
Three product lines covering 90%+ of rod-pumping applications.
API 11AX · Plunger 1.00"–2.50"
Classic insert rod pumps for conventional beam pumping — the tubing stays in the well, the pump is retrievable. Full RHA / RHB / RWA / RWB series with multiple barrel types, metallurgies, and hold-down configurations.
API 11AX · 500+ BPD
Run as part of the tubing string — ideal for wells requiring larger plunger diameters and higher displacement. THA / THB / TWA / TWB series, plunger diameters up to 3.75", from our Brazi facility with full traceability.
API 11B · 11AX
Sucker rods, fiberglass rods, hollow rods, barrels, plungers, valves, and accessories. API-compliant, in-stock for common sizes, with same-day dispatch available. Built for fast workover turnarounds.
When frac sand, high GOR, or combined challenges disable conventional pumps — speciality designs take over.
6 designs · Frac · formation sand · iron sulfide
When conventional pumps fail in sandy wells, specialty designs take over. From the Game Changer vented plunger and Frac Pump U-cup seals to Hollow Tube and Mercury travelling-barrel designs — we have a solution for every solids-heavy well.
3 designs · High-GLR · up to 4,000 m depth
For gassy wells where conventional pumps gas-lock. Capture Chamber, Balanced Pressure tapered barrels, and 2-stage Gas Compressor designs — each moves gas efficiently through the pump, preventing gas lock and fluid pound.
High Compression Sand Defender
For the hardest wells — producing both sand and gas. The Sand Defender combines a long Mercury-style traveling plunger, API B11/B12 barrels, high-compression insert cages, and wear-resistant metallurgy to survive dual-challenge environments.
Submit your well parameters — depth, fluid properties, GOR, sand loading, temperature — and our engineering team returns a tailored rod-pump recommendation with full specs, BOM, and drawings. 24–48 hour turnaround.
Our engineering team can recommend the right pump configuration for your well conditions — from standard API designs to full custom solutions.
