It comprises of heavy duty above and underground piping system with accessories.
The hydrant valves are provided at strategic locations (After every 30M, 1200mm to 1500mm above Ground level.
The water supply to the lines should be provided form a stored water tank filled 365 days , also known as ‘Fire Well’.
This water well is connected to the pump room. Depending upon the site usage and area, a network of pipes are distributed with hydrant valves.
The fire pump station comprises of Jockey pump, Electric main pump and standby Diesel pump.
The fire hydrant pump is always kept pressurized with water.
As soon as the valves are released, the pressure drops and the Jockey pump will start immediately to compensate the pressure difference.
In the event of opening one or more hydrant valves for fire fighting, the Jockey pump would not be able to make up for the water loss resulting in further pressure drop. So when falling pressure reaches the pre-set pressure of the main pump, the main pump will start automatically. In case of power failure, Diesel driven pump will come into operation.
