A jockey pump is a crucial component of fire protection systems, commonly found in high-rise buildings, industrial facilities, and other structures requiring reliable fire suppression capabilities. This pump serves a specific role within the fire pump system, which typically consists of a main fire pump and a jockey pump working in tandem.

The primary function of a jockey pump is to maintain pressure within the fire protection piping network at an optimal level, ensuring readiness for immediate response in the event of a fire. Unlike the main fire pump, which activates only when water flow is required to combat a fire, the jockey pump operates continuously to maintain pressure within the system.

When the pressure drops below a predetermined threshold due to minor leaks or gradual loss over time, the jockey pump automatically activates to replenish the pressure and keep the system primed for firefighting operations.
