Firefighting pumps

Fire fighting pumps

Fire-extinguishing and fire protection systems only get used in the event of a fire. They are filled with water and if not flushed, there is the danger that the water could become hygienically unsafe. If such systems are connected to a drinking water installation, they pose a danger to the drinking water. Stagnant water typically forms in fire-extinguishing systems. Stagnant water may lead to pathogenic germs forming. Under DIN 1988 and DIN EN 1717, process water systems such as fire-extinguishing systems are required to be isolated from public drinking water system, e.g. by means of free outflow protection devices (type: AA, AB). The potential hazard of bacteriological re-contamination of domestic and public drinking water systems has to be eliminated by law. In the drinking water separator station from WILO IndustrieSysteme, the certified free outflow type AB is integrated.
