A Few Fire Pump Facts
A fire pump is a part of a fire sprinkler system’s water supply and powered by electric, diesel or steam. 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. (wikipedia)
Fire pumps function either by an electric motor or a diesel engine, or, occasionally a steam turbine. If the local building code requires power independent of the local electric power grid, a pump using an electric motor may utilize, when connected via a listed transfer switch, the installation of an emergency generator.
The fire pump starts when the pressure in the fire sprinkler system drops below a threshold. The sprinkler system pressure drops significantly when one or more fire sprinklers are exposed to heat above their design temperature, and opens, releasing water. Alternately, other fire hoses reels or other firefighting connections are opened, causing a pressure drop in the fire fighting main.
Do I need a fire pump?
To determine if a fire pump is needed, the fire suppression system demands must be compared with the available water supply. If the supply cannot meet the demand, a fire pump is required. Conversely, if the water supply can meet the pressure and flow requirements, a fire pump is not needed.
What are the Australian Standards governing fire fighting pumps?
AS 2941:2013 sets out the requirements for pump set systems used in various types of fire protection systems such as sprinkler,hydrant, water spray and hose reel systems. The standard provides designers, manufacturers, installers and testers with minimum requirements for the design, manufacture, installation, commissioning and testing of fire pump sets including acceptance testing of electrical and compression-ignition drives. (The Pump Industry Association (PIA))
Routine maintenance of fire pumps sets is covered by AS 1851- 2012 and layouts compliance obligations realting to Monthly, 6 Monthly, Yearly and 5 Yearly service requirements.
What is fire booster pump?
Fire pumps are needed when the local municipal water system cannot provide sufficient pressure to meet the hydraulic design requirements of the fire sprinkler system. This usually occurs if the building is very tall, such as in high-rise buildings, or in systems that require a relatively high terminal pressure at the fire sprinkler in order to provide a large volume of water, such as in storage warehouses. Fire pumps are also needed if fire protection water supply is provided from a ground level water storage tank.
