What is the main purpose of a fire pump in a standpipe system?

The main purpose of a fire pump in a standpipe system is to provide water at higher pressure. Fire pumps are critical components because they ensure that sufficient water pressure is available for fire suppression efforts, especially in tall buildings or areas with low water pressure. The ability to deliver water at high pressure allows firefighters to effectively combat fires from a safe distance, ensuring that they can reach the fire and apply water effectively through hose connections.

While water storage, pressure measurement, and hose connections are important aspects of standpipe systems, they do not capture the primary function of a fire pump. The storage tanks hold the water, pressure gauges are used to monitor system status, and hoses enable the application of water. However, the unique role of the fire pump is to enhance the system's capability by elevating the water pressure to levels necessary for efficient firefighting operations.
