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.

KSB fire-fighting solutions: safe and reliable through experience

For more than 130 years, KSB has been manufacturing pumps and valves for the most diverse fire-fighting systems destined for applications in industry and building services. From in-house foundries and state-of-the-art research laboratories to seamless quality assurance, KSB offers you a globally unprecedented level of expertise. Together with its wholly-owned subsidiary Kagema, KSB supplies not only pumps, but also all other equipment required for stationary fire-fighting systems.
