Dear All,

Shall we introduce foam concentrate into water by using bladder tank  in  foam fire suppression system for aircraft hangar or we have to use foam pump to introduce foam concentrate into water . In NFPA 409 ,Clause 6.2.7 it states about Foam concentrate pump., my question shall we use bladder tank for the foam system for the aircraft hangar instead
of using a separate foam pump, is there is any area limitation for bladder tank application.

Regards,

Thoubeek
