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

The primary function of a booster pump in a sprinkler system is to increase the water pressure in the system. This function is crucial in ensuring that the sprinkler heads can effectively deliver water at the necessary pressure to produce the desired spray pattern and coverage area. In many cases, municipal water pressure may not be sufficient to adequately operate the sprinkler system, particularly in taller buildings or expansive areas. The booster pump compensates for this shortfall by taking in water at a lower pressure and elevating it to the required levels for efficient sprinkler operation. This enhanced pressure enables the system to maintain consistent and effective performance during activation, which is critical for fire suppression efforts.
