Normal pressure pumps 

Optimum efficiency thanks to spiral housing

Rosenbauer offers single-stage normal pressure pumps in the N series range of products. These centrifugal fire pumps achieve the best possible efficiency through three-dimensional impeller blades, the diffuser and the spiral housing.


The pumps of the N series stand out with their flat pump characteristic curves. Pressure surges when opening and closing the nozzles are reduced to a minimum.

Impresses with

  • Smaller pressure surges thanks to flat pump characteristic curve
  • Integration of wide range of foam proportioning systems
  • Highest priming performance and automatic priming
  • Pump pressure governor

Technical data

  • Single stage normal pressure pump
  • Sealing via maintenance-free mechanical sealing
  • Low speed, therefore no gearbox is usually needed - noise reduction
  • The normal pressure housing is designed as a spiral housing with integrated diffuser for the highest possible efficiency



  • Output of up to 2,500 l/min at 10 bar
  • Certified according to EN1028 FPN 10-2000
  • UL classified in accordance with NFPA1901 150-500



  • Output of up to 3,500 l/min at 10 bar
  • Certified according to EN1028 FPN 10-3000
  • UL classified in accordance with NFPA1901 150-750



  • Output of up to 4,500 l/min at 10 bar
  • Certified according to EN1028 FPN 10-4000
  • UL classified in accordance with NFPA1901 150-1250



  • Output of up to 5,500 l/min at 10 bar
  • Outputs in accordance with NFPA1901 150-1500 (5,680 l/min at 10 bar)

Piston priming pump (PPP)

  • KAP Professional
  • Automatic priming

Thanks to the unique drive system, the priming pump is always on stand-by to reduce wear and can be switched on at any time.

  • High priming performance
  • Safe to operate thanks to oil bath lubrication and inlet/outlet valves made from extremely resistant plastic
  • Resistant to waste water
  • Fail-safe thanks to dual piston redundancy

The priming pump is driven over a V-belt from the lantern or the gear-box. During the priming process the belt is tensioned via a lever. Once the priming process finishes, the belt is released.

The optional automatic priming system offers maximum operational safety during water supply.

The priming process starts automatically - the V-belt will be tensioned for this. When the pressure builds to about 1.5 bar inside the pump, the priming process is stopped by an extending cylinder that loosens the belt.

Operation and design

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

Integrated, automatic FIXMIX around-the-pump foam proportioning system

The integrated, automatic FIXMIX around-the-pump foam proportioning system is available for the N-pump series.


Modular system - a customized pump

The pumps of the N/NH series can be customized to requirements of firefighters - here's a brief extract:
