A fire pump’s size is dictated by the most hydraulically demanding area of the fire protection system. In many high-risebuildings,this canbe the automaticfirestandpipe system demandwhich requires 500gallons per minuteat 100pounds per square inchat the top of the most remote standpipe, plus 250 gpmfor each additional standpipe,up to a maximum of 1,0...
Selection of the fire pump depends on the building infrastructure and available space.The most common choices for fire pump drivers are electric motors and diesel engines. Electric motors requiring high horsepower are commonly run on 460 volt or higher, three-phase power. Steam turbinesare also an option,but are fairly uncommon. In buildings that a...
The total head of a fire pump is the energy imparted to the liquid as it passes through the pump, usually expressed in psi. For fire pumps such as horizontal split-case and vertical in-line centrifugal pumps that are required to operate under net positive suction head, the total head of a fire pump is calculated by adding the suction head(city pres...
NFPA 20 requires that a fire pump be supplied bya continually available power source, usually identified asan uninterrupted power source(NFPA 20-2013, Section 9.1.5and 9.2.1). In many cases, this requirement necessitates that a backupgenerator be provided as a secondary source in the event of a power failure, in which case the fire pump controller ...
An outside screw and yoke gate valve must be installed in the suction pipe to provide a means of isolation from the incoming supply line(NFPA 20-2013, Section 4.14.5.1). This is the only device that is explicitly permitted to be installed in the suction line within 50feetof the pump suction flange, though NFPA 20 does provide allowances for other e...
Lastly, when determining a location for a new fire pump enclosure, it is important toconsider service accessibility and proximity to the building exterior. A fire pump room shouldbelocatedon an exterior wall adjacent to the fire lane and above the floodplain. If the enclosure must be located inside, it shallbe accessible by a passageway with a fire...
