Mechanical / hydraulic

• Design: Centerline mounted casing, radially split casing, opposed impellers arrangement.
• Shaft: Heavy-duty shaft designed for minimum deflection, meeting API 610 / ISO 13709 deflection and rotor dynamics requirements.
• Wear Rings: Renewable wear rings with API 610 / ISO 13709 running clearances, positively locked.
• Bearings:
  • Heavy-duty radial bearing standard.
  • Heavy-duty thrust bearing: Duplex 40° angular contact standard, ring oil lubricated. Other bearing configurations available.
• Casing: Centerline mounted casing with heavy-duty mounting extensions to accept API 610 / ISO 13709 nozzle loads and maintain pump alignment. Radially split casing designed for high pressure/temperature services, with fully confined controlled compression gaskets.
• Flanges: CLASS 300 RF FLANGES STANDARD; other classes and facings optional.
• Seal Chambers: Enlarged seal chambers conform to API 610 / ISO 13709 dimensional requirements, allowing use of a wide range of API 682 / ISO 21049 cartridge mechanical seals.
• Maintenance: Casing head on outboard end allows removal of rotor without disturbing suction and discharge piping.
• Materials: Available in a wide range of materials, including all API 610 constructions and custom application needs.
• Hydraulics: Engineered hydraulics with dense coverage to better match processes for efficiency and reliability; custom hydraulics are available.
• Hydraulic Coverage: The provided hydraulic coverage charts illustrate flow capacity and total dynamic head for 50 Hz and 60 Hz operation, representing 80% to 110% of best efficiency point (BEP). See the official PDF for exact tabulated values.
• Packaging: Engineered packaging with a wide range of drivers, seals, piping, nozzle configurations, flanges, base plates, and QC testing.

Applications

• Petroleum refining, production, and distribution
• Petrochemical and demanding chemical processing
• High temperature applications, including boiler circulation
• General industrial applications requiring high temperature or high pressures
• Refinery specific applications: Process feed, reflux, splitter bottoms, high-pressure process transfer
