A fire pump is a part of a fire sprinkler system's water supply. 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 provide water flow at a higher pressure to the sprinkler system risers and hose standpipes. A fire pump is tested and listed for it's use specifically for fire service by a third-party testing and listing agency, such as UL or FM Global. The main code that governs fire pump installations in North America is the National Fire Protection Association's (NFPA) NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection.

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 firehoses reels or other firefighting connections are opened, causing a pressure drop in the fire fighting main. Fire sprinklers are an active fire protection measure subject to stringent bounding. ... Indoor firehose A firehose is a thick, high-pressure hose used to carry water or other fire retardant (such as foam) to a fire to extinguish it. ...


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 which require a relatively high terminal pressure at the fire sprinkler in order to flow 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. High-rise is a 1975 novel by J. G. Ballard. ...


Types of pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction.


A jockey pump is a small pump connected to a fire sprinkler system in parallel with the fire pump. It maintains pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause an appreciable pressure drop which will be easily sensed by the fire pump automatic controller, causing the fire pump to start. The jockey pump is essentially a portion of the fire pump's control system.
