What is the most common range of GPM for fire pumps?

The range of 500-1500 gallons per minute (GPM) is the most common for fire pumps, particularly because this range is well-suited for a variety of firefighting applications and building types. Fire pumps in this range provide sufficient water flow to combat fires effectively in residential, commercial, and industrial settings. They are typically utilized in situations where immediate response and reliable water supply are critical, such as in urban fire departments or for large facilities that may require an enhanced firefighting capability.

Pumps with capacities beyond this range, such as those above 1500 GPM, are generally used for specific large-scale operations or in industrial applications where extensive water supply is needed. Conversely, pumps under 500 GPM may not provide adequate flow for larger structure fires which require a higher volume of water to suppress effectively. Therefore, the 500-1500 GPM range represents a balance between sufficient flow and practicality for a wide array of firefighting scenarios.
