Flowserve HPX-Mag API Process Pump
The HPX-Mag sealless pump is designed on the renowned Flowserve HPX API 610 process pump. This horizontal, overhung, single-stage, radially split, end-suction, top-discharge, centerline-mounted pump features high-efficiency magnetic coupling. Commonly used in the oil and gas and hydrocarbon industries, it provides excellent leakage prevention and can withstand high pressures, temperatures, and hostile/toxic fluids. The HPX-Mag magnetic drive pump meets API 685 requirements.
High-efficiency magnetic coupling drives the horizontal, overhung, single-stage, radially split, end-suction, top-discharge, centerline-placed HPX-Mag pump.
HPX-Mag API Process Pump Applications
- Petroleum production, distribution and refining
- Petrochemical and chemical processing
- Difficult-to-seal liquids
- Toxic, aggressive or flammable liquids
- High-temperature applications
- Gas industry services
- Biofuels
- Boiler circulation
- Power plants
- General industrial
Based on the established hydraulic design of the Flowserve HPX API 610 pump, it offers the following performance-boosting characteristics:
- Robust construction meets or exceeds API 685 criteria, ensuring zero emissions in challenging-to-seal, poisonous, aggressive, or flammable liquids.
- Hermetically sealed design eliminates external flushing systems and mechanical seals.
- Dynamic thrust balancing provides smooth operation over a large flow range and limits vibration.
- Raised mean time between maintenance (MTBM) lowers maintenance costs and downtime.
- Back-pullout design reduces labor expenses and simplifies maintenance operations.
- Thorough hydraulic coverage enables perfect selection for maximum running efficiency.
- Parts interchangeability with HPX API 610 reduces parts inventory and carrying costs.

HPX-Mag API Process Pump Benefits
- Internal flushing uses process fluid to cool the magnet and lubricate the sleeve bearings; external flushing plans are available upon request.
- Alloy C4 containment shell provides excellent corrosion resistance; ceramic ZrO? shell option offers zero-eddy current loss. Both are fully drainable and self-venting.
- Silicon carbide (SiC) radial and thrust bearings accommodate high-temperature expansion; optional materials available.
- Rare earth samarium-cobalt magnets deliver high torque and slip-free performance at elevated temperatures.
- Backup regenerative rings protect the shell and prevent leaks in failure events.
- Consolidated hydraulic design shares casing and impeller with the HPX API 610.
- Back-pullout design simplifies maintenance without disturbing motor or piping.
- Centerline-supported casing withstands nozzle loads beyond API 685 standards; guiding vane reduces NPSH dependency.
- Dynamically balanced impeller reduces vibration and ensures smooth operation.
- Renewable wear rings lower replacement costs; secured with set screws or tack welds.
