What is the primary function of a booster pump in fire apparatus?

The primary function of a booster pump in fire apparatus is to enhance water flow for firefighting. Booster pumps are designed to increase the pressure of the water being supplied to fire hoses, allowing firefighters to deliver water more effectively to suppress fires. This increase in pressure enables the fire service to reach greater distances and heights, which is critical in combating fires in multi-story structures or areas where water pressure might be insufficient.

This function is essential during firefighting operations because it ensures adequate water supply and pressure at the nozzle, ultimately enhancing the efficiency and effectiveness of fire suppression efforts. Therefore, the ability of a booster pump to improve water flow directly supports the operational needs of firefighters when they are engaged in their primary task of saving lives and property during a fire emergency.
