Jockey Pump
What Are Jockey Pumps in A Fire System?
A jockey pump in a fire system is an essential component in putting out fires, especially in high-rise buildings. Working together with fire sprinkler systems, jockey pumps help distribute water to areas that normal company equipment cannot reach.
A jockey pump is a small device that works with a fire pump to maintain pressure in a fire sprinkler system. It is powered by electricity, diesel or steam, and is connected to a static water source, such as a river or water tank.
The jockey pump provides water flow at a higher pressure to activate the sprinkler system. Building owners need to ensure that it is fully functioning to keep their occupants and property safe during an emergency.
Why Is Having A Jockey Pump in A Fire System Important?
If there is one component that should be considered the heart of a building’s fire safety system, it’s the jockey pump. This device drives adequate pressure to the fire sprinkler system, one of the first defenses against a fire. Jockey pumps maintain the pressure in the sprinkler system so that the fire pump doesn’t have to run all the time. It also protects the sprinkler system from damage during a fire when water rushes into the pipes.
A jockey pump is especially necessary in a fire system when the local water system cannot provide enough pressure to meet the hydraulic design requirements of the fire sprinkler system. This occurs in high-rise buildings or facilities that require high terminal pressure to transfer water, such as storage warehouses. Jockey pumps are also needed if a fire protection water supply is provided from a ground-level water storage tank.
How Does A Jockey Pump Work?
A fire sprinkler system consists of pipes with pressurized water, with its heads designed to open at a certain temperature. When opened, the water pressure in the pipes drop since water is flowing out of them.
A fire pump then sends more water through the pipes to put out the fire. During this process, a jockey pump keeps the water pressure within a specific range, to protect the sprinkler system.
