What is the recommended pressure for pumping progressive hose packs?

The recommended pressure for pumping progressive hose packs is typically 150 PSI. This pressure is recognized as optimal for achieving a balance between effective flow and manageable friction loss in the hose. At 150 PSI, firefighters can ensure that they have sufficient water flow to effectively combat fires while also maintaining control over the equipment and easily managing the hose's behavior on the fire ground.

This pressure allows for a strong and steady stream of water, which is crucial for effective fire suppression. It is also considered a standard within many fire departments for various hose configurations, ensuring uniformity and predictability when crews respond to incidents.

Lower pressures might result in insufficient water delivery for effective firefighting, while higher pressures could lead to excessive strain on hoses and equipment, increasing the risk of failures or accidents. Thus, 150 PSI strikes the necessary balance for hose pack operation during firefighting efforts.
