3. WHAT IS FIRE
HYDRANT SYSTEM ?
Fire hydrant pump systems are widely known as
• Fire pumps
• Hydrant boosters
• Fire water pumps
Features:
• High pressure system, specially intended to enhance
the fire fighting power in case building is set on fire

4. FIRE HYDRANT
SYSTEM
A fire hydrant system is a safety measure
or emergency equipment required in
some buildings that comprises a series of
components that when assembled
together provide a source of water to
assist fire authorities in a fire.

5. TYPES OF HYDRANTS
5
• Dry riser hydrants
• Used where temperatures are expected to fall
• Valve of the hydrant place in the base of a hydrant, to
prevent water from freezing
• Wet riser hydrants
• used in locations where temperatures don’t drop below
the freezing point
• These hydrants always have water in the barrel and after
each use

6. WORKING PRINCIPLE OF FIRE
HYDRANT PUMP
• 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
• 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
• The user attaches a hose to the fire hydrant, then opens a valve on the hydrant to
provide a powerful flow of water, on the order of 350 kPa (50 pounds per square
inch gauge (psig))
• This pressure varies according to region and depends on various factors
including the size and location of the attached water main).

• Diesel pump
• Heavy or medium grade pipes
• Hydrant valves
• Hose boxes
• Hoses
• Nozzles & branch pipes
• Fire brigade inlet
• Isolation valves
• Air release valve

9. WATER SUPPLY AND
STORAGE
A water supply for a fire
hydrant system can be derived
from a reliable source of water
such as; street mains, static
water supply such as a tank or
dam.

10. PIPEWORKS
ANDVALVES
To direct the water from its point of origin (supply) to
its destination (hydrant valve) requires a series of
interconnected pipes at defined size

11. • A point of attachment for the fire
brigade to provide additional water
to a fire hydrant system in in the
event of an emergency

FIRE BRIGADE BOOSTER

12. BOOSTER PUMP SET
12
In some circumstances where the a
hydraulic analysis has determined that
the water supply is insufficient for the
building requirements, one or more
booster pump sets may be require

13. HYDRANT
13
• The end-point of a fire hydrant system is the
Hydrant (also known as a Hydrant Valve,
Landing Valve or Millcock)
• strategically located throughout a building in
accordance with the provisions of AS2419

14. LAY FLAT FIRE HOSE
14
A lay flat fire hose is a flexible hose and
nozzle that may be connected to a hydrant.

15. JOCKEY PUMP
• Also known as a pressure
maintenance pump
• A small apparatus works together
with a fire pump as part of a fire
protection sprinkler system
• Designed to keep pressure in the
system elevated to a specific
level when the system is not in
use
• Also prevent system from
damage when a fire happens and
water rushes into the pipes

16. WORKING OF JOCKEY PUMP
• Fire Sprinkle system
It consists of
• Pipes with pressurized water
• Head, work according to temperature
