Hi Everyone,

How to decided number of standby for fire water pumps and also how to decide drivers requirement of fire water pumps ? e.g. diesel or electrical driven


For example, fire water demand for plant is 1200 GPM. Hence I will select 3 number of working pump with capacity 400 GPM. Then I am assuming that at a time only one pump will be under maintenance / failed to operate. So I will select 3 working + 1 standby pump. Capacity of standby pump will be same as working pump. I will consider redundant (two independent source of power) power supply to all pump.  Is this correct approach ? Can anyone guide me about requirement standby and drivers requirement as per NFPA ?
