What is the range of pump capacities for aerial apparatus?

The range of pump capacities for aerial apparatus is generally understood to be within 1500 to 2000 gallons per minute (gpm). This capacity is designed to meet the operational needs of firefighting in high-rise buildings and other significant structures where aerial apparatus are deployed.

Aerial apparatus, such as ladder trucks, require sufficient pump output to effectively deliver water at height and to sustain operations in critical fire suppression scenarios. While certain aerial apparatus may be capable of higher flow rates, the standard range established for most configurations is indeed between 1500 and 2000 gpm. This specification ensures that the apparatus can maintain an effective firefighting operation while also being manageable in terms of weight, size, and maneuverability.

The selected answer aligns with these operational standards, demonstrating an understanding of the typical capabilities of aerial apparatus in fire service. Other ranges would typically exceed what is commonly required or implemented in most fire departments, as they may prioritize efficiency and effectiveness over maximum possible output.
