What is the amount of pressure created by the pump after receiving pressure from a hydrant or another pump called?

The amount of pressure created by the pump after receiving pressure from a hydrant or another pump is referred to as net pump discharge pressure. This pressure reflects the actual usable pressure available to deliver water through the fire suppression system, taking into account both the pump's capabilities and the system's operational conditions.

Net pump discharge pressure is important for understanding how effectively water can be delivered to the nozzle or other outlets during firefighting operations. It allows operators to assess the performance of the pump and ensure that the necessary pressure is available to overcome any losses in the system, such as those caused by friction in hoses and fittings. This measure provides a realistic view of how much pressure is actually available for effective firefighting at the moment of operation, which is essential for maintaining adequate flow rates and achieving successful outcomes during emergency responses.
