Number of Fire Pumps?
Number of Fire Pumps?
(OP)
According to European Standards we have to use two Fire Pumps when we are installing a water tank in stead of a public water supply.
I can not find anything in the NFPA 13 regarding the demand of number of Fire Pumps. I hope a friendly soul could post the table concerning this? Please.

I know if you use the FM codes, you are only allowed to use a FM approved Fire Pump. But what about the NFPA codes - should it be FM approved? Or does it only have to comply to the NFPA 20?
RE: Number of Fire Pumps?
NFPA 20 only requires the pump and controller to be listed - it does not prescribe who performs the listing.

If the pump breaks down, there will be no water supply to the sprinkler system as opposes to when the systems is supplied from a public water supply. In this case it is ok with only one Fire Pumpe, because you will have to install a by pass, so you still have water coming from the public water supply (because there will be some pressure left in the public supply - but just not enough, which demands a Fire Pump) in case of Fire Pump break down.
But maybe I am missing something?

My experience overseas is most public water supplies are either very minimal or not available. Thus the requirements for a tank and 2 pumps. Keep in mind the duration of the water supply is significantly less then NFPA requirements and many times the densities are less two. Most times they require two diesel pumps.
IBC requires two sources of water for high rise buildings, mostly public main and a pressure tank. Or in NYC a pump and a wood gravity tank on the roof.
