HWMA High-Head Overhung API Process Pump
The HWMA is a single 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, Hydrogen, Boiler Feed Booster, Hydrotreating, Catalytic Cracking, LNG, Caustic and Chlor-alkali, Leaching Acid, Chemical and Liquor (pulp and paper), Cooling Water (power), Plating, Galvanizing and Other Coatings, Residuum and Heavy Oil Upgrading, Solvents, Digester, Volatile Organic Compounds, Distillation (oil and gas), Water Supply and Treatment (oil and gas), Drilling and Production, Water and CO2 Injection, FPSO, Gas Treating and Sulfur Recovery, Heavy Oil, Oil Sands and Shale - Industries:
Oil and Gas, Power Generation, Primary Metals, Mining, Chemical Processing, General Industries, Pulp and Paper - 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.
Heavy-Duty Motor Support Head features a registered fit motor mount and does not use spacer plates.
