A fire pump is a crucial component of a fire protection system that provides high-pressure water for sprinklers, standpipes, and hydrants when pressure in the system drops. It boosts water flow from a source like a municipal supply or a storage tank to ensure effective fire suppression, particularly in buildings where gravity or municipal pressure is insufficient. Fire pumps can be powered by electricity, diesel engines, or steam turbines and are a key part of ensuring the reliability and effectiveness of a building's fire safety infrastructure.
