What is an HPX Mag Drive Process Pump?

The HPX mag drive pump uses a magnetic coupling to transmit torque from the motor to the impeller, removing the need for a dynamic shaft seal. The pump’s containment shell forms a sealed barrier between the process fluid and the atmosphere.

This design significantly reduces:

  • Fugitive emissions

  • Environmental exposure

  • Unplanned downtime related to seal failure

HPX pumps are designed to meet the requirements of ISO and ANSI process pump standards, supporting consistent performance in chemical and petrochemical services.

Application and Materials Configuration for HPX Mag Drive Pumps

Flowserve HPX Mag Drive Process Pumps are specified for applications where leak-free operation, chemical compatibility, and controlled performance are critical. Correct application and material selection is essential to support safe containment and long-tem lifecycle reliability.

Advantages of HPX Mag Drive Pumps in Industrial Systems

Flowserve HPX magnetic drive pumps are designed for zero-leakage operation in regulated and hazardous process environments.

By eliminating dynamic seals and fully containing the process fluid, the HPX supports compliance requirements while reducing emission risk, safety exposure, and unplanned maintenance in continuous-duty industrial systems. 

  • Eliminates mechanical seal-related failures
  • Improves plant safety in hazardous fluid applications
  • Reduces environmental and compliance risk
  • Lowers total cost of ownership through reduced maintenance
  • Provides consistent performance under continuous-duty conditions

Correct selection is essential. Oversizing, incorrect materials, or operating outside design limits can compromise reliability and internal component life.

Hydraulic & Containment Features Reliability & Maintenance Features

Internal Flushing
Internal flushing utilising process fluid serves to cool the magnet area and provide lubrication for the sleeve bearings. External flushing options are also available upon request.

High-torque Magnets
High-torque magnets crafted from rare earth samarium-cobalt effectively eliminate slippage and ensure exceptional resistance to high temperatures.

Backup Renewable Rings
Renewable backup rings crafted from non-sparking material safeguard the containment shell and mitigate fluid leakage in the event of a failure.

Centerline-supported Pump Casting
The pump casing, supported at the centerline, is designed to withstand nozzle loads surpassing API 685 standards. Equipped with a suction nozzle guide vane, it minimises inlet vortexing and promotes uniform flow into the impeller, thereby ensuring a dependable NPSH margin.

Precision Cast Impeller
The precision-cast impeller undergoes dynamic balancing to minimise vibration and ensure seamless operation across a broad flow spectrum. It is securely fastened using a set screw and locknut, both isolated from contact with the fluid.

Leakage-free Containment Shell
The containment shell, constructed from alloy C4 material, ensures leak-free performance, boasting high efficiency and exceptional corrosion resistance. Additionally, a containment shell made from ceramic ZrO2 material is offered to eliminate eddy current losses. Both options are available to suit varying needs.

Lubricated Radial & Thrust Bearings
Radial and thrust bearings, lubricated for smooth operation, are crafted from silicon carbide (SiC) material. Their tolerance fit accommodates expansion in high-temperature environments. Optional materials are also provided to fulfil specific application requirements.

Consolidated Hydraulic Design
The consolidated hydraulic design incorporates the identical casing and impeller found in the renowned HPX API 610 pump model.

Back Pullout Design
The back pullout design streamlines maintenance by ensuring that the motor and piping remain undisturbed during servicing.
