How much water can portable pumps deliver?

Portable pumps are commonly used in firefighting operations due to their versatility and ability to deliver substantial amounts of water to combat fires, especially in areas where traditional water supply systems may not be accessible.

The correct answer indicates that portable pumps can effectively deliver up to 500 gallons per minute (gpm), which reflects a typical capacity for many models used in firefighting. This flow rate is sufficient for various firefighting tasks, allowing for rapid water application to suppress flames and protect structures.

The other options represent flow rates that might exceed the capabilities of many standard portable pump models. While there are indeed portable pumps that can reach those higher capacities, 500 gpm is a widely recognized standard, ensuring that firefighters have a reliable and consistent amount of water available in their operations. It balances efficiency and practicality in scenarios where quick deployment and mobility are critical.
