PROBLEM TO BE SOLVED: To enable quick fire extinction by causing a pressure of a fire hydrant to rise steeply when a start switch of the fire hydrant is operated in the event of a fire.;SOLUTION: A fire hydrant pump system includes a fire hydrant pump for sending water from a water source to a fire hydrant provided on each floor on a demand side through a water pipe; an inverter for driving the fire hydrant pump; pressure detection means for detecting a pressure on a fire hydrant pump discharge side; a start switch disposed on the fire hydrant for transmitting a start command signal; and frequency control means for, responding to a signal of the signal transmission means, setting a target pressure for each floor from a pipe resistance curve obtained for each floor beforehand, and a corresponding assumed frequency, and outputting a frequency command signal to the inverter so that the pressure detected by the pressure detection means is the target pressure, so as to control the pump. At the initial start time of the pump, the frequency control means outputs the assumed frequency to the inverter.;COPYRIGHT: (C)2014,JPO&INPIT
