HWMA2 API Process Pump
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.
- 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.
