General

Innovative technology. Ergonomic operation.

 The pumps of the NH series enable output at normal and high-pressure. The arrangement of the normal and high-pressure impellers opposite each other on a common pump shaft result in an ideal axial thrust load compensation.

Through this arrangement, no additional drive is required for the high-pressure pump. The high-pressure stage can be easily turned on or shut down by opening or closing the water supply.

High Pressure Stage Version

  • Normal and high-pressure stage arranged on a common shaft
  • Arranged opposite one another for best possible axial thrust load compensation
  • High pressure switched on and off by opening or closing the water supply – no additional switch elements needed
  • Version of the high pressure pump also as centrifugal pump
  • Thus making it resistant to contamination
  • Smaller pressure surges through flat pump characteristic curve
  • Very good foam qualities with high-pressure FIXMIX system

Operation

Highest level of user friendliness and ergonomics

In the development of the new pump series, special importance was placed on the following measures to increase user friendliness and ergonomics to the highest level:

  • Integrated LCS (Logic Control System)
  • Illuminated control panel
  • Color coding of various unit conditions, foam, electrics
  • Uniform operation of all Rosenbauer products
  • Clear organization of display, control and mechanical controls
  • Ergonomically shaped handles – designed for firefighting gloves
  • Low operating height – screw-down valves at suction pipe level
  • Tilted display and control fields at eye level – safely and quickly legible
  • Visually attractive cover

Technical Data

  • Single-stage normal pressure pump and four-stage high-pressure pump on a common shaft
  • Sealing via maintenance-free mechanical sealing
  • Low speed, so usually no gear-box needed – noise reduction
  • Design of the normal pressure housing as spiral housing with integrated diffuser for highest possible efficiency
