CronoNorm-NLG is a baseplate pump with axial suction.

This single-stage, horizontal spiral housing pump is used for a variety of clean, slightly contaminated , cold and hot water applications.

Applications

  • Pumping clean or slightly contaminated water (max. 20 ppm) without solid matter for circulation, transfer and pressure boosting purposes
  • For pumping cold and hot water (in accordance with VDI 2035) without abrasive substances in heating, cold water and cooling water systems
  • Applications in municipal water supply, irrigation, building services, general industry, power stations, etc.

Key features / benefits

  • Motors with IE2 technology for higher efficiency fitted as standard
  • Reduced life cycle costs due to optimised efficiency
  • Bidirectional mechanical seal with forced flushing
  • Interchangeable wear ring
  • Low NPSH values, best cavitation properties
  • world-wide high availability of IEC standard motors

Technical data

  • Permissible temperature range -20°C to +120°C
  • Mains connection 3~400 V, 50 Hz
  • Protection class: IP55
  • Nominal diameter DN 150 to DN 300
  • Max. operating pressure 16 bar
