What is the primary function of a fire pump in a sprinkler system?

The primary function of a fire pump in a sprinkler system is to increase water pressure and flow. In cases where the municipal water supply lacks the necessary pressure or flow to effectively deliver water through the sprinkler system, fire pumps are utilized to enhance these parameters. This ensures that a sufficient volume of water is available to suppress or extinguish a fire quickly, which is critical for life safety and property protection.

Fire pumps are specifically designed to deliver a higher pressure than what can be achieved from a standard water supply, thereby allowing the sprinkler heads to operate effectively over a larger area, even in high-rise buildings or areas with inadequate water supply. The ability to increase water pressure and provide a reliable flow rate is essential for meeting fire code requirements and ensuring the efficient functioning of sprinkler systems during an emergency.
