Technical Data
Note:
The mobile backflow preventer BFW112 in accordance
with DIN 14346 is connected to existing standpipes or
pillar hydrants to take water for fire fighting from the
pipeline network. It prevents water from flowing back into
the drinking water supply network as a result of back
siphonage or back pressure, if the pressure in this
network is lower than that in the pipeline laid for
firefighting purposes.
Note:
In addition, pressure surges do not occur in the network,
which helps to prevent burst pipes.
