Jockey pump
Jockey pump is mainly used for fire sprinkler system to maintain the pressure in sprinkler pipe.
In a fire protection system, there are typically two types of pumps: the main fire pump and the jockey pump. The main fire pump is responsible for supplying water at a high flow rate to the sprinkler system in case of a fire. On the other hand, the jockey pump is a smaller pump that operates at a lower pressure and is used to keep the system's pressure steady during non-fire conditions.
