API 610 OH2 Pumps
Most major manufacturers (such as Flowserve, Sulzer, or ITT Goulds) design their OH1 lines to meet these general parameters.
Standard flow rate: Up to 1,100 m³/h (approx. 11,000 gpm).
- Head: Up to 220 m
- Pressure rating: 51.8 bar g
Industry and application
API 610 OH2 pumps (specifically the A-series) are heavy-duty, single-stage, horizontal centrifugal pumps designed for the most demanding environments within the oil and gas, petrochemical, and chemical industries.
API 610 OH2 pumps (A-series) are primarily designed for demanding process applications in the oil and gas, petrochemical, and chemical industries. They are engineered to handle clean, cold, or hot fluids under high pressure and high temperature conditions.
Design and construction
- Configuration: Horizontal, overhung, centerline-mounted pumps with single-stage end suction and centerline discharge.
- Standards: Fully compliant with the latest API 610 (12th edition) and ISO 13709 standards. They are also ATEX/UKEX compliant for hazardous areas.
- Back pull-out design: Enables easy maintenance by allowing removal of the rotating unit without disturbing the piping or motor.
- Durability: Designed for a service life of 20–25 years with a minimum of 3 years of uninterrupted operation.
Typical industry contexts
- FPSOs and platforms: Ideal for locations where space is limited and high reliability is required in harsh offshore environments.
- Petrochemical plants: Engineered for handling corrosive and hazardous chemicals, such as caustic transfer.
- Power plants: Used for secondary cooling and critical water treatment processes.
- Carbon capture: Increasingly used in carbon capture and storage (CCS) facilities to move process fluids.
Handled fluid types
- Hydrocarbons: Crude oil, gasoline, diesel, and LPG.
- Process chemicals: Amines, caustics, and acids (using exotic alloys for corrosion resistance).
- Water: Seawater, produced water, condensate, and potable water.
- Temperature-sensitive fluids: Can handle fluids up to 370–380 °C with integrated cooling systems.
Primary applications
- Upstream (Offshore/Onshore):
- Produced water: Handling water separated from oil/gas.
- Seawater duties: Transfer and treatment systems on FPSOs and platforms.
- Low NPSH requirements: Applications where suction pressure is low to prevent cavitation.
- Midstream and downstream (refineries):
- Hydrocarbon transfer: Moving crude oil, fuels, and intermediate products.
- Refinery process duties: General circulation and processing in refinery units.
- LPG and amine: Handling liquefied petroleum gas and amine (used for gas sweetening).
- Utilities and industry:
- Boiler feed: High-temperature water supply for steam generation.
- Condensate recovery: Returning condensed steam to the boiler system.
- Booster pump duties: Increasing pressure in pipelines or process loops.
- Fuel transfer: Transporting diesel, kerosene, or other fuels.
