Product Description

The mobile backflow preventer BFW112-65AC in accordance with DIN 14346 is connected to existing standpipes or pillar hydrants to draw 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 the supply network is lower than in the fire hose. In addition, pressure surges do not pass into the network, which helps to prevent burst pipes.
