How many gallons per minute does a fire pump use?


The flow rate of a fire pump can vary depending on the specific type and capacity of the pump. Fire pumps are designed to deliver water at high pressures and flow rates to extinguish fires effectively. Typically, fire pumps are rated in gallons per minute (GPM) or liters per minute (LPM).

Smaller portable fire pumps, such as those used for firefighting in rural areas or by first responders, may have flow rates ranging from 60 to 300 GPM (227 to 1,136 LPM).

Larger fire pumps used in commercial buildings, industrial facilities, or municipal firefighting systems can have much higher flow rates. These larger pumps may range from 500 GPM (1,893 LPM) to over 5,000 GPM (18,927 LPM) or more, depending on the specific application and fire protection needs.

It's important to note that the flow rate of a fire pump can also be affected by the available water supply and the pressure requirements of the fire suppression system. Proper sizing and design of fire pumps are critical to ensuring they can deliver the necessary water flow and pressure for effective fire suppression.
