A jockey pump, often an essential component of a fire protection system, plays a crucial role in maintaining the pressure within a fire sprinkler system. This compact and high-pressure pump is typically used in conjunction with a larger fire pump to ensure that the system's water pressure remains at the desired level. The jockey pump operates continuously or intermittently to compensate for small leaks, minor pressure losses, or fluctuations in demand, thus preventing the main fire pump from constantly cycling on and off. This not only extends the life of the primary pump but also ensures that water is readily available for firefighting without delay, helping to safeguard lives and property in the event of a fire. In summary, the jockey pump is a vital component in maintaining the reliability and effectiveness of fire sprinkler systems by keeping water pressure consistent and ready for action.
