Product Description
The Petrochemical Process Pump is an API 610 OH1/OH2 overhung centrifugal pump purpose-built for refinery and petrochemical services. Its centerline-mounted casing handles thermal growth at process temperatures up to 400°C, while the heavy-duty shaft and bearing assembly ensures long life under high-pressure conditions. With flow rates to 2,600 m³/h and heads to 260 m, this pump manages hydrocarbon transfer, reactor feed, and light-end services. Material options include cast steel, alloy steel, and duplex for corrosive process streams.
Applications
- Oil refineries
- Petrochemical complexes
- Natural gas processing
- LNG terminals
- Crude oil transfer
- Hydrocarbon processing
Quality Assurance
All Petrochemical Process Pumps are manufactured under ISO 9001 quality management system. Each pump undergoes rigorous testing including hydrostatic pressure test, performance test, NDT inspection, and dynamic balance verification before shipment. We provide comprehensive documentation including test reports, material certificates, and operation manuals.
Why Choose Our API 610 Process Pumps
Petrochemical Service Optimized
Designed specifically for petrochemical process duties including naphtha transfer, gas oil circulation, reflux service, and reactor feed, with material selection per NACE MR0175 for sour service.
High-Temperature Capability
Centerline mounting option for services above 150°C, with carbon steel or alloy casing rated for continuous operation up to 350°C in hydrocarbon and thermal oil service.
Seal Flush Plan Support
Pre-configured seal flush plans (Plan 11, 21, 23, 32, 53A/B/C) with all piping and instrumentation included, ready for installation per API 682 requirements.
Low Vibration Operation
Precision-balanced rotating assembly (ISO 1940 Grade G2.5) and rigid shaft design ensure vibration levels below 2.8 mm/s RMS at BEP, extending bearing and seal life.

Selection Guide
✅ When to Choose This Pump
- Refinery and petrochemical process service
- High-temperature (above 150C) hydrocarbon pumping
- Critical service requiring API 610 compliance
- High-pressure injection and transfer duties
⚠️ When NOT to Choose
- Low-pressure water utility service (over-specified)
- Strong acids requiring fluoroplastic lining
- Solids-laden slurries (requires slurry pump)
- Below-grade sump applications (use vertical sump)
💡 Common Selection Mistakes
- Ignoring NPSH calculation for hot hydrocarbons
- Using single seal for toxic/flammable service
- Not specifying centerline mounting for >150C
- Under-sizing motor for specific gravity >1.0
