HPX ISO 13709/API610 (OH2) Hydrocarbon Processing Pump
Flowserve HPX ISO 13709, API 610 OH2 Hydrocarbon Processing Pump
| Brand: | Flowserve |
|---|---|
| Type: | OH2, single stage, overhung centrifugal process pump |
| Standards: | ISO 13709, API 610 (OH2), ISO 21049, API 682 |
| Description: |
The Flowserve HPX is an API 610 OH2, ISO 13709 compliant single stage overhung process pump designed for hydrocarbon processing duties in refineries and petrochemical plants. It is engineered to deliver stable performance, reduced vibration and long service life in demanding process conditions, while supporting emissions containment through an ISO 21049, API 682 seal chamber. If you are specifying an OH2 pump for critical service, the HPX offers broad hydraulic coverage for accurate selection and efficient operation. Share your duty point, fluid details, temperature and pressure and we can help you match the right HPX configuration, materials and seal arrangement. |
Engineered and built for reliable, safe performance, the HPX also provides optimal emissions containment. The wide hydraulic coverage range helps support precise selection for strong operating efficiency.
Key Features and Benefits
- Centerline supported casing, helps manage nozzle loads and reduce shaft misalignment for extended rotor, bearing and seal life
- Suction nozzle guide vane, promotes uniform flow and helps maintain a strong NPSH margin
- Dynamically balanced precision cast impeller, minimizes vibration and supports smooth performance over a wide flow range
- Back pull out design, simplifies maintenance without disturbing piping or motor
- Renewable wear rings, reduces replacement part cost for casing and impeller wear components
- ISO 21049, API 682 seal chamber, supports multiple seal configurations for demanding hydrocarbon service
Why engineers specify HPX for hydrocarbon pump service
- Designed for refinery and petrochemical duties where reliability, stability and containment matter
- Strong mechanical design to support longer service intervals and predictable maintenance
- Selection flexibility across a wide hydraulic range for accurate duty point matching
