Why do booster systems have to be sized with pumps having an additional 5 psi of boost pressure?
In a booster system, there are always inherent system pressure losses from the interconnecting piping, isolation valves and PRVs (or check valves). In order to ensure that a booster system will be able to pass its 0 to 100 % flow test and produce the required boost pressure throughout this range, Armstrong has determined that the selected pumps must have an additional 5 psi of pressure over the booster system pressure rating.
