Detailed explanation of jockey pump

The jockey pump is a kind of fire pump. It's used to stabilize the pressure of the automatic sprinkler system and the fire line water force system, so that the system water pressure is always in the needed pressure state. Once the sprinkler or fire line comes out of water, it can flow out to meet the requirements of fire fighting water volume and water pressure.

The jockey pump and the supporter pump are both types of constant pressure installations for fire pumps. The supporter pump works when the sprinkler head and fire line haven't flowed out, and the supporter pump works when the sprinkler head and fire line have discharged water, but the water pressure of the fire fighting water is inadequate, and the water pressure needs to be increased. Different from the supporter pump, the pressure stabilizer pump is used to keep the tone- scattering system and the fire line system under the needed pressure conditions. Its function is veritably egregious, so the supporter pump appertained to in the specification basically refers to the stabilizer pump, especially the stabilizer pump of the automatic sprinkler system.
When the pressure of the fire pipe network( spray, fire line) is advanced than the set( design value), the supporter pump will automatically stop running. When the pressure of the fire pipe network( sprinkler, fire line) is lower than the set( design value), the supporter pump will start automatically.
