What is jockey pump and fire pump?
A jockey pump is a small pump connected to a fire sprinkler system to maintain pressure in the sprinkler pipes. This is to ensure that if a fire-sprinkler is activated, there will be a pressure drop, which will be sensed by the fire pumps automatic controller, which will cause the fire pump to start.
Is jockey pump required for standpipe system?
General requirements of Jockey Pump: The jockey pump shall not be required to have alternate or standby power.
Why it is called jockey pump?
On a fire protection system requiring a fire pump, there is a small pump that maintains pressure above the pressure settings of the larger fire pump. Hence the name “jockey pump.” The purpose of a jockey pump is to maintain pressure in a fire protection piping system so the larger fire pump does not need to run.
What is the pressure of jockey pump?
1) The jockey pump stop point should equal the pump churn pressure plus the minimum static supply pressure. 2) The jockey pump start point should be at least 10 psi (0.68 bar) less than the jockey pump stop point. 3) The fire pump start point should be 5 psi (0.34 bar) less than the jockey pump start point.

What is fire pump system?
07/21/2021. A fire pump is any type of purpose-driven pump used within a fire protection system. It can be driven by diesel engines, electric motors or even steam and is used to provide increases in water pressure to meet the design requirements of a fire protection system. Fire pumps do not create a water supply.
How much pressure is in a fire pump?
Fire pumps are rated by the manufacturer to produce a certain amount of net pressure (typically between 40 and 250 psi) at their rated flow. It is important to note that the rated net pressure usually only occurs at the rated flow of the pump.
How does a fire jockey pump work?
Why is jockey pump needed?
A jockey pump, also know as a pressure maintenance pump, maintains the pressure in the fire sprinkler system to avoid non-emergency starting of the main fire pump. This keeps the main fire pump from short cycling, which shortens its life span.
