WebDec 22, 2024 · In our example, we have a required flow of 1,475 gpm for our sprinkler system and hose allowance. A selection of a 1,000 gpm fire pump would put the flow at 147.5% of rated capacity and could work, but is slightly out of the recommended range. A 1,250 gpm fire pump would put the flow at 118% of rated capacity.
