Foam proportioning system
12.3 Foam proportioning system
Approved foam compound
All components of the Rosenbauer foam proportioning systems, e. g.:
housing, piping and sealing materials, are resistant in operation to all types
of commercially available foam compounds.
In principle all commercially available foam compounds for firefighting can
be used with similar hydraulic properties to water.
Any other foam compound only by arrangement with Rosenbauer.
• Pre-mixing systems: foam compound with a kinematic viscosity of < 60
cSt.
12.3.1 Around-the-pump foam proportioning system
Lubrication Oil-bath lubrication
Output of the priming pump at 3.0 m suction lift - 4 seconds
at 7.5 m suction lift - 25 seconds
