Product Description
The Heavy-Duty Petrochemical Process Pump is an API 610 OH2 overhung centrifugal pump engineered for the most demanding refinery and petrochemical applications. Its robust centerline-mounted casing handles temperatures to 400°C (with cooling) and heads to 350 m, with flow rates from 2.5 to 2,000 m³/h. The pump features heavy-duty shaft and bearing assemblies, premium mechanical seals with API flush plans, and material options including carbon steel, 316L, duplex, and Hastelloy. Ideal for reactor feed, hydrocarbon processing, and high-temperature corrosive services.
Applications
- Refinery process services (crude, gasoline, diesel)
- Petrochemical plant feed and transfer
- Corrosive chemical handling
- High-temperature hydrocarbon services
- Gas plant liquid handling
Quality Assurance
All 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
Heavy-Duty Process Construction
Thick-walled cast steel casing with reinforced flanges, oversized shaft diameter, and heavy-duty bearing housing designed for continuous 24/7 operation in harsh petrochemical and refining environments.
Wide Hydraulic Coverage
Multiple impeller trims available for the same casing, covering flow rates from 50 to 800 m³/h and heads from 30 to 200 m. Allows standardization across multiple services with one pump frame.
API 682 Seal Chamber
Large-bore seal chamber compatible with API 682 single, dual, and tandem mechanical seals, with seal flush plan connections (Plan 11, 21, 23, 32, 53) pre-drilled for easy installation.
Proven Field Reliability
Thousands of units operating in refineries and chemical plants worldwide, with mean time between failures (MTBF) exceeding 5 years in properly maintained installations.

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
