Fire Water System

[mechatronic]

I have to select Fire Water pumps.

NFPA is not specific on any Codes to be followed for Pumps - it says any pump with conformance to Hydraulic Institue Standards is Fine

NFPA 20 gives guidelines is only for Installation.

API models are not required since this is not a Oil/ Gas area

Please help me what standard should I refer

Pumps sizes are

1. 95 Liters per Second

2. 160 Liters per Second
3. 7 liters per Second

All to deliver at 8.8 Kg gauge

NFPA requires a listed fire pump be installed, I believe FM and UL are the only fire pump listing agencies in north america.

1. 1500 USGPM
2. 2500 USGPM
3. 111 USGPM

The first two you would traditional use a horizontal split case, double suction pump, although nowaday they have the upright inline pumps that are cheaper.

If you were drafting from a pond you would use a vertical turbine pump. The last one is pretty small and uprights have tradionally been used in this role.

You should likely get in touch with a fire pump supplier like ITT to help get yourself oriented.

I don´t understand what you reffer to NFPA 20 is only for installation, it gives a lot of requirements on design and the pump and the controllers, and following NFPA 20 I think one must think of a listed UL/FM pump.

Other manufacturers to obtain information:

-Patterson
-Armstrong
-ITT/AC
-Peerless
-R-B pump (reddy buffaloes)
-Floway fire pumps (vertical)

David,

NFPA 20 says any pump which is manufactured as per the requirements of Hydraulic Institute is acceptable.

Of course NFPA 20 gives guide lines on controls, Starting, issues on Heads Vs delivery etc.

But these are only general stipulations. NFPA does not say a specific standard - For example API - ASME ... etc

In anycase thanks David for inputs
