Foam sprinkler systems

Foam sprinkler systems use foam to extinguish fires in buildings. The fire sprinkler pump distributes the water and foam mixture via the pipe system and discharges the foam spray via the sprinklers.

Foam systems use a mixture of water and a low expansion foam concentrate to extinguish fires in buildings. The fire pump distributes the water and foam mixture via the pipe system and discharges the foam spray via the foam sprinkler heads.

The foam systems are connected to a water supply through a valve that is opened by the operation of a smoke or heat detection system. The foam is injected in the pipe, after the fire-pump, from a foam bladder tank to allow it to be mixed with the water.

The foam system can operate like any of the other fire sprinkler systems (Wet, Dry, Pre-action and Deluge systems). This means the system is activated either by activating the heat sensing element on the sprinkler heads or via the fire detection system.

Foam Deluge systems are used in places that are considered high hazard areas, such as power plants, off shore oil rigs, aircraft hangars and chemical storage or processing facilities.

Grundfos supplies fire pumps for water supply as part of foam sprinkler systems for industrial and commercial fire protection.
