The Flowserve HPX-V vertical inline pump is engineered for reliability, safety and long service life in API process applications.

Key features include:

1. Vertical inline casing designed to withstand nozzle loads in accordance with ISO 13709 and API 610 requirements, minimizing shaft misalignment and extending rotor, bearing and seal life.
2. Raised face flanges manufactured to ASME B16.5 Class 300 standards, with surface finishes meeting ISO 13709 and API 610 requirements. ISO and JIS flanges are available.
3. Metal to metal casing and cover fit with a controlled compression gasket to ensure proper sealing and alignment.
4. Suction nozzle guide vane that reduces inlet vortexing and ensures a stable NPSH margin.
5. Dynamically balanced precision cast impeller for reduced vibration and smooth operation across a wide operating range.
6. Renewable casing and impeller wear rings to lower maintenance and replacement costs. All pump sizes include a back wear ring as standard.

ISO 21049 / API 682 compliant seal chamber capable of accommodating a wide range of seal arrangements, including single, dual pressurized and unpressurized cartridge seals. Full API 682 flush plans are available.

HPX-V API Process Pump Application

The Flowserve HPX-V vertical inline process pump is designed for demanding services involving high pressures and elevated temperatures.

Typical applications include:

1. Oil refining production and distribution
2. Petrochemical and chemical processing
3. Gas industry services
4. Biofuels processing
5. High temperature duties such as boiler circulation
6. Water and general industrial services

The HPX-V pump uses the same impeller, wear rings, bearings and shaft diameter under the seal as the HPX horizontal pump. This interchangeability allows users to standardize components across pump installations, reducing spare parts inventory and overall operating costs.

Frequently Asked Questions (FAQ) – HPX-V API Process Pump

• What is the Flowserve HPX-V pump used for?
  The Flowserve HPX-V is a vertical inline API 610 OH3 process pump designed for high pressure and high temperature services in oil and gas, hydrocarbon processing, petrochemical and general industrial applications.

• What does API 610 OH3 mean for the HPX-V pump?
  API 610 OH3 refers to a single stage, overhung vertical inline centrifugal pump configuration standardized for refinery and petrochemical services.

• How is the HPX-V different from the HPX horizontal pump?
  The HPX-V is a vertical inline pump designed for space saving installations, while the HPX is a horizontal overhung pump. Both share the same shaft diameter and impeller design, allowing component standardization.

• Is the Flowserve HPX-V compliant with ISO 13709?
  Yes. The HPX-V pump fully complies with ISO 13709 and API 610 requirements for OH3 process pump designs.

• What are the main advantages of the HPX-V vertical inline design?
  The vertical inline configuration reduces footprint, supports high nozzle loads, minimizes shaft misalignment and improves rotor, bearing and seal life in demanding services.

• Can the HPX-V pump handle high temperature and high pressure applications?
  Yes. The HPX-V pump is designed to operate at temperatures up to 400°C and pressures up to 42 bar, making it suitable for severe process conditions.

• What industries commonly use the HPX-V API process pump?
  Typical industries include oil refining, petrochemical and chemical processing, gas services, biofuels, power generation, water and general industrial applications.

• Does the HPX-V support API 682 mechanical seals?
  Yes. The pump is equipped with an ISO 21049 API 682 compliant seal chamber that supports a wide range of single and dual cartridge seal configurations.

• Can spare parts be shared between HPX-V and HPX pumps?
  Yes. The HPX-V uses the same impeller, wear rings, bearings and shaft diameter under the seal as the HPX horizontal pump, reducing spare parts inventory and lifecycle costs.
