Fire pumps are necessary when the water supply available does not generate the necessary hydraulic pressure required to meet demand of a fire protection system such as automatic sprinklers and standpipes, or even foam systems. An example would be a high-rise building where the pressure from a city supply line is not great enough to overcome gravity to reach the top of the building. In this instance, installing a fire pump is done to provide a boost to get the necessary pressure to the top. It is important to remember to have a steady supply of water so that the fire pump may operate correctly.
