Thank you dear for the advice regarding selecting 1250 HPM @ 15 Bar. The thing is that some suppliers such as XYLEM don't manufacture sump flow at 225 psi head. They have it at 215 psi max. In case NFPA 20 covers the selection, I guess optimizing the pump would have greater benefits such as...
Dear littleinch,
The building is 15 storey with 55 meters high. The fire flow is what NFPA 1 stipulates for hydrants flow. The standpipe requires 1000 GPM at 15 Bar whereas the hydrants require 1500 GPM @ 1.4 Bar.The scenario is simple but the outcome is an 1500 GPM @ 15 Bar.I need to know...
Greetings,
I have a high rise hotel where fire flow is requested to be 1500 gpm while standpipe demand is 1000 gpm. The required minimum pressure for the hydrants (1500 gpm) is 20 psi and for the stanpipe is 225 psi. The designer selected a fire pump of 1500 gpm at 225 psi. I guess this system...
