NFPA #20, 2003, 11.2.4.1.1. "Engines shall be provided with a governor capable of regulating engine speed within a range of 10 percent between shutoff and maximum load condition of the pump."
Does this mean that a 1760 rpm rated engine running at 1860 rpm is acceptable? If a 1760 rpm rated pump when tested produced 1860 rpm (less than 10%) can the pressure produced at the higher rpm be used for the system calculations? In other words can the actual pump test be used for the system calc's or must we use the manufacturers data sheet regardless the test results? The pump is a PLD if that matters.
