1. Pressure Requirements: Sprinkler systems require a certain amount of water pressure to effectively distribute water over the protected area. If the available water pressure from the municipal water supply or other sources is not sufficient, a fire pump can boost the pressure to meet the requirements of the sprinkler system.

2. Elevation and Distance: In tall buildings or buildings with multiple stories, the water pressure from the city's water supply might not be sufficient to reach the upper floors or cover the entire area of the building. A fire pump can provide the necessary pressure to reach these higher elevations and ensure adequate coverage.

3. Water Supply Limitations: If the available water supply is limited in terms of flow rate or pressure, a fire pump can help compensate for these limitations and provide the required water flow and pressure to the sprinkler system.
   

   

4. Simultaneous Usage: In some cases, a building might have other water-consuming systems operating simultaneously, such as domestic water use or industrial processes. A fire pump can ensure that there's enough water pressure and flow for both the sprinkler system and other systems during an emergency.

5. Code and Standards: Fire codes and standards, such as those set by the National Fire Protection Association (NFPA) and local authorities, often dictate when a fire pump is required for a sprinkler system. These codes take into account factors like building size, occupancy type, water supply conditions, and more.
