They can direct flow to one side outlet at full capacity while . The purpose for the 10x distance is to prevent turbulent flow from entering the fire pump and impeller which can cause wear and cavitation over time. NFPA 24 provides guidance on suction pipe sizes and generally states that for any system, the pipe should be at least 6-inches in nominal diameter. The philosophy is that suction pipe be sized so that when the pump is operating at its maximum flow rate, which is 150% of its rated capacity or the maximum flow available from the water supply, the gauge pressure at the pump suction flange does not drop below -3 psi (-0.2 bar). 6/29/2020 08:03:44 am.
