FIRE PUMPS
Fire pumps may be powered either by an electric motor or a diesel engine, or, very 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.
Fire pumps are needed when the local municipal water system cannot provide sufficient pressure to meet the hydraulic design r
equirements 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..
