Fire pumps are used in water-based fire protection systems. They help to distribute water throughout the sprinkler system so every part of the building is protected in case of a fire. Fire pumps are responsible for increasing the water pressure in order to reach the pressure demand for the building or space they’re used in. For high-rise buildings or expansive spaces like warehouses, if the existing water supply cannot provide adequate pressure to deliver water along all parts of the sprinkler system, a fire pump is required.
