HPX-V Vertical In-Line Process Pump

Brand: Flowserve Corporation

Industry-leading Performance in a Compact Footprint

The HPX-V vertical in-line pump from Flowserve is more than just a space-saving alternative to many horizontal process pumps in upstream and downstream services. Based on the widely used Flowserve HPX horizontal process pump — a long-time workhorse of the oil and gas industry — the HPX-V vertical in-line pump offers you many of the same industry- leading benefits:
  • Robust construction that meets or exceeds ISO 13709/API 610 (OH3) ensures you will have safe, reliable performance in high-temperature and high-working pressure applications.
  • Stringent emissions containment is achieved with an ISO 21049/API 682-compliant seal chamber, which accommodates all seal models and styles, including advanced gas barrier seal technology.
  • A comprehensive range of configurations and hydraulic coverage enables precise selection for best operating efficiency.
  • Parts interchangeability with the HPX horizontal pump enables you to reduce parts inventory and carrying costs.
  • Back pullout design simplifies maintenance activities and reduces associated costs.
Features
Features and Benefits
  • In-line vertical casing withstands nozzle loads per ISO 13709/API 610 requirements to minimize shaft misalignment and extend rotor, bearings and seal life.
  • Raised face flanges are to ASME B16.5 criteria for Class 300. Surface finish meets ISO 13709/API 610 standard. ISO and JIS flanges are available.
  • Casing and cover feature a metal-to-metal fit with a fully confined controlled compression gasket to ensure proper sealing and alignment.
  • Suction nozzle guide vane reduces inlet vortexing and ensures a reliable NPSH margin.
  • Dynamically balanced precision cast impeller minimizes vibration to ensure smooth operation over a wide flow range.
  • Renewable casing and impeller wear rings reduce parts costs. Back wear ring is standard on all pump sizes. Optional arrangements and materials available.
  • ISO 21049/API 682 seal chamber accommodates a wide variety of seals, including dual pressurized and unpressurized cartridge types for the most severe services. A full complement of API 682 seal flush piping plans is available.
  • Shaft design is well within ISO/API shaft deflection and run-out criteria.

Reliability, Maintenance and Safety-enhancing Design
  • Cartridge seal mounting assures ease of maintenance and precise seal face setting for maximum seal life.
  • Dynamically balanced impeller limits vibration and assures smooth operation over a wide flow range.
  • Positively locked anti-rotation impeller nut avoids erroneous operation.
  • Standardized mounting plate is provided to maintain the API 3:1 ratio from the unit center of gravity to prevent tipping.
  • Optional larger mounting plates accommodate mounting of seal pot assemblies and heat exchangers.
  • Back pullout rotating assembly simplifies maintenance, as neither the motor nor piping connections are disturbed.
  • Coupling guard is provided to enclose the coupling, pump shaft and motor shaft areas.
  • Renewable wear rings for both casing and impeller reduce replacement parts costs. Wear rings are secured by axial screws as standard; tack welding optional.
Heavy-duty Bearing System

The bearing housing of the HPX-V is made of heavy-duty carbon steel. Standard labyrinth-type oil seals retain oil and exclude atmospheric contaminants and moisture. Optional bearing isolators are available. Oil sump bearing is cooled using standard fan air cooling.

Bearing size selection is standardized together with the HPX (OH2) overhung horizontal process pump line to maximize spare parts availability.

Choice of Bearing Lubrication:
  • Oil cascade lube design for temperatures to 385°C (725°F)
  • Oil mist design for temperatures to 400°C (750°F)
  • Grease lube design for temperatures to 275°C (525°F)
