Under normal circumstances, a fire hydrant system is pressurized with water ready for emergency use. When a hydrant valve is opened, the system experiences a drop in water pressure.
The drop in water pressure is detected by a pressure switch which in turn starts the booster pump, drawing water from the water supply to increase the water pressure of the system. Required more water pressure then start electrical driven fire pump or diesel driven fire pump.
Water from the hydrant is then directed through the layflat fire hose to a nozzle which is then directed to the seat of a fire.
During a fire the fire brigade may provide additional water and boost the water pressure to satisfy the demands of the fire hydrant system.
This is carried out by connecting a fire appliance (truck) between an alternate water supply and the booster connection.
A fire pump is a part of a Sprinkler/Hydrant system’s water supply and can be powered by electric and diesel. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g. tank, reservoir, lake) The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes.
