 FIRE PUMP APPLICATION  Fire Pumps are used to supply water for
automatic sprinkler systems, standpipes or fire hydrants. NFPA No.
20 classifies fire pumps as split case, vertical turbine, end
suction, or In-Line design. In-Line fire pumps have capacities of
50, 75, 100, 150, 200, 250, 300,400, 450, 500, and 750 GPM; End
Suctionpumps are rated for 100, 200, 250, 300, 400,450, 500, and
750 GPM; Split case and vertical turbine fire pumps are rated 150,
200, 300, 450, 500, 750, 1000, 1250, 1500, 2000,3000, 3500, 4000,
4500, and 5000 GPM.All fire pumps are rated at 40 pounds per square
inch or more of boost.  Fire Pumps of the type described shall meet
the following basic requirements:  1.Each pump is to be tested
hydrostatically for not less than 5 minutes. The test pressure is
to be not less than 1.5 times the maximum working pressure of the
pump, but in no case less than 250 psi (1724 kPa).  2.A pump shall
develop not less than 65 percent of rated total head when
discharging at 1.5 times rated capacity.The maximum net ressure for
a fire pump shall not exceed 140 percent of rated head.  3.The
maximum pump brake horsepower shall not exceed the HP rating its
driver, including service factor.
