Jockey fire pumps are pressure maintenance pumps used to maintain the normal operating pressure of the system in sprinklers and other water-based fire extinguishing systems. When a small drop occurs in the system pressure, they activate to provide the necessary pressure support.
The primary task of the jockey fire pump is to compensate for the system pressure decreasing due to normal leaks and small pressure drops. Thanks to this operation, it helps prevent the main fire pump from starting unnecessarily solely due to minor pressure fluctuations before an actual fire condition occurs.
In sprinkler systems, the jockey pump is evaluated to meet small flow requirements under normal operating conditions of the system. When a sprinkler opens in the event of an actual fire, if the water demand exceeds the capacity of the jockey pump, the system pressure continues to drop, creating the necessary conditions for the main fire pump to start.
Jockey fire pumps are generally preferred as centrifugal, mostly multi-stage pump structures capable of providing low flow and high pressure. This structure allows the pressure required by the fire extinguishing system during standby to be maintained with a compact pump.
The maximum working pressure specified for this product is 15 bar, and the flow range is 22.7 – 227 m³/h. Pump selection and pressure settings must be made according to the design conditions of the fire extinguishing system it serves and the requirements of relevant standards.
