Foam-water sprinkler systems for flammable liquid storage and handling areas. The fire sprinkler pump distributes the water & 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. They provide for actual extinguishment of the fire and a lower water demand. Foam water spray systems can be used for discharge of water first, followed by discharge of foam for a pre-determined period, and then followed by water until manual shut off.
