Brand: IDP
Description:

The Flowserve HWMA2 is a two-stage, vertical in-line overhung pump designed in accordance with ISO 13709/API 610 (OH3) standards. It features a separate bearing housing and a compact footprint, making it ideal for low-flow, high-head applications in industries such as oil and gas, petrochemical, and power generation. The HWMA2’s modular design allows for over 80 best efficiency point (BEP) fits within a single pump size, optimizing efficiency and reducing energy consumption.

The HWMA2 pump utilizes back-to-back, radial blade impellers to achieve high-head performance while equalizing axial thrust. Its robust construction includes features such as a replaceable volute insert for precise hydraulic customization, a heavy-duty motor support head with a registered fit motor mount, and an optional inducer to reduce NPSH requirements. These design elements contribute to the pump’s reliable operation and ease of maintenance in demanding process environments.

Flowserve’s HWMA is a two stage, vertical in-line overhung pump with a separate bearing bracket. With its small footprint, this low flow, high head process pump is a space-saving alternative to many overhung process pumps in upstream and downstream services.

HWMA2 ISO 13709 Applications

Heat Transfer Fluids, Gas to Liquids, Acid Transfer, Hydrocracking, Boiler Feed Booster, Hydrotreating, Catalytic Cracking, Industrial Gases, Caustic and Chlor-alkali, LNG, Chemical and Liquor (pulp and paper), Leaching Acid, Cooling Water (power), Crude, Product and CO2 Pipeline, Plating, Galvanizing and Other Coatings, Desalination, Residuum and Heavy Oil Upgrading, Digester, Solvents, Distillation (oil and gas), Volatile Organic Compounds, Drilling and Production, Water Supply and Treatment (oil and gas), FPSO, Water and CO2 Injection, Gas Treating and Sulfur Recovery, Heavy Oil, Oil Sands and Shale

  • Industries:
    Chemical Processing, General Industries, Water Resources, Power Generation, Oil and Gas
  • Standards:
    API682, API610

Replaceable Volute Insert permits precise hydraulic customization. Each insert is engineered for specified head and flow requirements. Accommodates future system changes.

Casing and Cover feature metal-to-metal fits with fully confined, controlled compression gasket to ensure proper sealing and alignment.

Raised Face Flanges are to ASME B16.5, Class 300 for one stage and Class 600 for two stage models.

ISO 21049/API 682 Seal Chamber accommodates a wide variety of seal configurations including dual pressurized and unpressurized cartridge types for the most severe services.

Stiff Shaft Design limits deflection at seal faces to 0.05 mm (0.002 in) max. Vibration levels are well below that required by ISO 13709/API 610. (insert period)

Heavy-Duty Motor Support Head features a registered fit motor mount and does not use spacer plates.
