What is the purpose of a fire pump in relation to sprinkler systems?

The purpose of a fire pump in relation to sprinkler systems is to boost water pressure. In fire protection systems, adequate water pressure is essential to ensure that sprinkler heads can distribute water effectively and cover the necessary area to suppress a fire. When a building's water supply does not provide sufficient pressure, a fire pump is employed to enhance that pressure.

Fire pumps are commonly used in scenarios where there is a reliance on municipal water supply, which may not maintain the required pressure under fire flow conditions. By increasing the water pressure, a fire pump ensures that water can reach the upper floors of high-rise buildings or supply multiple sprinkler heads simultaneously during an emergency.

While recharging the system after use, eliminating air from the pipes, and removing impurities from the water may be relevant tasks in managing a sprinkler system, these functions do not directly relate to the primary role of a fire pump, which focuses on ensuring adequate water pressure to protect life and property from fire hazards.
