What is the rated capacity of the water pump at 250 psi?

• A. 500 GPM
• B. 750 GPM
• C. 1000 GPM
• D. 1250 GPM

Answer: (B)

In fire rescue operations, the rated capacity of a water pump at a given pressure, like 250 psi, involves understanding the performance curves of the pump. Typically, pump specifications detail how much water (in gallons per minute, or GPM) can be moved at different pressures. For pumps that are commonly used in fire rescue, a capacity of 750 GPM at 250 psi aligns well with the standard operational benchmarks for many fire apparatus under those pressure conditions. This implies efficiency in water delivery while maintaining effective pressure for firefighting operations. Selecting a maximum rated capacity of 750 GPM ensures that the pump can handle substantial water flow needed for effective firefighting while avoiding excessive strain or inefficiency. Higher capacities, such as 1000 GPM or 1250 GPM, would usually be associated with either higher pressure capabilities or different configurations that are not standard for 250 psi operations. In essence, the selection of 750 GPM reflects a balance of capability, performance, and safety in line with fire service standards and practices.
