N/NH Series - The Truck-Mounted Fire Pump with Global Experience
The development of the ROSENBAUER N/NH series is driven by the experience of firefighters all over the world. Everything is driven by firefighting experience and geared for firefighting operations.

For airport, industrial or municipal fire trucks - the ROSENBAUER N / NH series pumps have a global reputation for:  

• Normal-pressure pumps from 500 GPM to 1,000 GPM
• Combined normal and high-pressure pumps
• Flat pump output characteristic
• Best-of-breed priming performance
• Automatic priming
• Automatic around-the-pump foam proportioning system "FIXMIX"
• Pressure governor DRE2.3
• Mechanical thermal protection
• Modular - custom-built to match your requirements
• Internationally approved and certified

  N / NH pumps are suitable for tough, continuous operation with any kind of water and foam compound quality and in a wide range of climatic conditions. Firefighters all over the globe rely on the ruggedness and operating safety of the ROSENBAUER N/NH series centrifugal fire pumps.

Description
The FEECON Around-The-Pump Proportioner is a simple
and inexpensive way to add foam capability to all discharges
of a truck. There are two types of AP Kits: one has a manual
metering valve and the other has an automatic multi-metering
valve. The manual metering valve can be adjusted
for different flow rates; the automatic style is used when
the flow rates are constant at each outlet on the truck.
The AP System design diverts a portion of the water pump’s
output from the discharge side of the pump and sends it
through an eductor. A vacuum is created at the eductor’s
foam concentrate inlet, and this vacuum draws foam concentrate
through the metering valve and into the eductor.
This foam/water mixture is then sent to the suction side of
the water pump where it mixes with the incoming water
and is distributed throughout the discharge piping.

Features
• Foam At All Outlets
• No Friction Loss or Elevation Restrictions
• Variable Flow Rates
• Simple To Use
• Inexpensive

System Components
• Eductor
• Metering Valve: Either manual style (mounted on the
pump panel),or automatic style.
• Operations Nameplate: To be mounted on the pump
panel, next to manual metering valve.
• Swing Check Valve: To be mounted between the
eductor and metering valve.
• Ball Type Shut-Off Valves: One valve is installed in
the system as the foam concentration tank shut-off,
and the other, piped in before the eductor, is installed
as the eductor supply valve. These valves can be customer
supplied or supplied in Feecon AP Kits.

System Advantages
• Variable Flow Rate: The discharge rate can be adjusted
for the specific application. The rate is infinitely
variable up to the maximum flow of the unit.
• Variable Pressure: The system operates at any pressure
between 125 & 250 PSI (8.5 & 17 bars).
• The pump engagement procedure is the same with
foam or with water.
• No Back Pressure Restrictions: The unit is not affected
by hose length or elevation loss.
• No Nozzle Restrictions: The unit operates with any
size or type of fixed gallonage nozzle.

Rosenbauer Fix-Mix A fully mechanical, automatic around-the-pump foam proportioning system is available for the N / NH series pumps. The system is fully embedded in the pump. Benefits: Simple operations Excellent foam compound suction performance Completely maintenance-free Fully mechanical proportioning system Up to 4 different proportioning rates for a single pump: three for normal and high-pressure operations an additional rate for high-pressure-only operation Supported proportioning rates of 0.5%, 1%, 3% and 6% can be freely combined Proportioning rate does not depend on pump capacity or pressure The HP-FIXMIX around-the-pump foam proportioning system is available for foam generation, using the high-pressure pump. The high-pressure proportioning system can be used in a stand-alone setup or in combination with the normal-pressure proportioning system.  An NH pump can support up to seven different operating states
