In a relay pumping operation, what is the pressure at which pumps achieve their maximum flow?

In a relay pumping operation, the correct pressure at which pumps achieve their maximum flow is 150 PSI. This value is crucial because it reflects the optimal pressure range that enables the pumps to operate most efficiently, maximizing the volume of water they can deliver.

At this pressure, the hydraulic performance of the pump is best suited for maintaining high flow rates, which is essential in scenarios such as relay pumping where multiple pumps work in tandem to ensure an adequate supply of water over long distances or across varying terrain. Understanding this pressure helps fire service personnel ensure that they are deploying the equipment and resources efficiently, ultimately improving their effectiveness during fire suppression efforts.

Thus, identifying and maintaining the pump operation around this pressure helps to achieve the best performance while minimizing the risk of operational failures such as cavitation or excessive wear on the pump components.
