Six water connections for fire-fighting water

Fire Fighting

Fire-fighting systems and sprinkler pumps from KSB safeguard you in the event of fire

In fire protection systems, operating reliability is crucial. The flawless operation of KSB’s products ensures the supply of fire-fighting water in the event of a fire.

Effective fire protection places high demands on fire-fighting systems

In Germany alone, a fire breaks out on average every three minutes. The earlier its spread can be tackled, the lower the damage. This is why engineers often equip modern industrial plants and buildings with automatic fire-fighting systems. But fire-fighting systems have to meet exacting requirements: Despite only operating for short periods, the pumps must quickly deliver their full performance in the event of a fire as well as offering high levels of corrosion resistance in general. Various fire-fighting techniques impose additional demands: Water spray systems operate at particularly high pressures, and foam extinguishing systems require pumps built from materials impervious to the medium.
