Fire pumps overview
Fire pumps maintain water pressure in sprinkler systems. Sprinkler systems must have a strong, reliable water supply. In some cases, the standard supply is not enough. Water pressure must be increased by a pump.
Fire pumps may be required in certain circumstances, such as when the water supply is a below-ground reservoir or for high-rise buildings. They turn on when the water pressure in the sprinkler system is too low. A pump is a must if the municipal water supply does not provide enough water pressure to supply the sprinkler system.
The technology
A jockey pump maintains high pressure in the sprinkler system while it is closed. Fire pumps use a sensor to monitor the water pressure in the sprinkler system. When a sprinkler opens, the sensor notes a drop in water pressure. The control sensor then activates the pump. The pump maintains the water pressure at safe levels. It ensures each sprinkler that opens will be able to spray water where needed. Some systems have fire department connections. If these are used, this can also cause a drop in water pressure. This would also turn on the fire pump.
Fire pumps may be powered electrically, or by gas or diesel engines. In some setups, they can run on generator power. They are vital to the safe operation of many sprinkler systems. Most pumps need weekly inspection and annual testing. Testers look for signs of wear and verify that output is enough to supply the sprinkler system.
Applications
Standpipes are a part of the construction in many new buildings either instead of or in addition to sprinkler systems. They are generally required in buildings which are tall, large, or highly specialized. Some buildings, such as lumber yards, need a larger water flow. These also require fire pumps.
