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

The primary function of a fire pump within a sprinkler system is to supply additional water pressure when needed. In fire protection systems, water supply pressure may be insufficient to ensure that the sprinklers can effectively deliver the necessary amount of water to control or extinguish a fire. Fire pumps are specifically designed to increase the water pressure to the required level, ensuring that the sprinklers can operate effectively, even in high-demand situations or when the municipal water supply lacks the necessary pressure.

Understanding the role of fire pumps is crucial because they not only enhance the performance of the sprinkler system but also improve the overall effectiveness of fire suppression efforts. Without the capability to augment water pressure, sprinklers might not adequately reach the intended areas, leaving gaps in fire protection coverage. This highlights the importance of maintaining and testing fire pumps to ensure they function properly in an emergency.
