Industrial direct injection foam proportioning system 

Foam as needed

The Rosenbauer MIXMATIC industrial proportioning system is a direct injection foam proportioning system for industrial use that is vehicle-independent. Foam can be individually mixed, per outlet, from 1% to 7%. A centrifugal pump is used as foam concentrate pump, driven via an extra diesel engine.

Impresses with

  • Water pump free of foam
  • Large foam compound volumes
  • Individually adjustable proportioning rate per outlet
  • Foam compound output independent of vehicle type
  • Usage of different foam compound sources


  • Own foam concentrate pump with drive
  • The foam concentrate pump drive is regulated so that the pressure on the foam side always remains at 0.5 bar above the pressure on the water side
  • Venturi proportioners on all outlets adjust the quantity of foam compound to the corresponding water quantity
  • Individually adjustable proportioning rate per outlet
  • Proportioning rate continuously adjustable from 1% - 7%
  • Easy operation thanks to Rosenbauer LCS
  • External suction
  • Foam compound tank filling possible

Proportioner per outlet

One foam compound valve and one proportioner are installed on each outlet. This means you can individually adjust the proportioning rate per outlet, between 1 and 7%.

Proportioner sizes with corresponding output (in liters):


The corresponding proportioner must be installed according to water flow.

  • 1 1/2" : 75 to 340 l/min
  • 2 1/2": 380 to 1,200 l/min
  • 4": 1,320 to 4,500 l/min
  • 6": 2,570 to 9,500 l/min

Foam compound pump

  • Centrifugal pump with 450 l/min or 700 l/min at 16 bar
  • With gunmetal housing and gunmetal impeller, shaft made from stainless steel
  • Driven via an extra diesel engine - no drive necessary from the vehicle
  • The foam compound can be supplied either from up to two foam compound tanks or from an external foam compound source
  • Foam compound pumps can also be used to fill the foam compound tank and to supply other vehicles


  • Various sizes of the foam compound pump (800 lpm or 1,200 lpm at 17 bar or 240 lpm on request only)
  • Foam compound tank filling after operation
  • Different number and sizes of outlets
  • Foam compound pressure outlet to supply other vehicles



  • Operation via LCS 2.0 operating system - best implementation in vehicle and pump operation or via switches (from Kraus & Nehmer)
  • Selection of foam compound source or the foam compound tank filling via the control panel
  • Setting the proportioning rate manually directly on the outlet or via the display for the turret (for LCS 2.0 operation)
