Jockey pumps help extend the lifespan of fire pumps by maintaining system pressure and preventing unnecessary cycling of the main fire pump. By handling minor pressure fluctuations and small leaks, jockey pumps reduce the wear and tear on fire pumps, which would otherwise start and stop frequently to maintain pressure. This reduced cycling minimizes mechanical stress on the fire pump’s components, such as bearings, seals, and impellers, thereby prolonging its operational life. Additionally, jockey pumps consume less power and operate more quietly than fire pumps, leading to energy savings and reduced noise pollution in facilities. By ensuring that fire pumps only operate during actual emergencies, jockey pumps contribute to the long-term reliability and efficiency of the fire protection system.

The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has an ultra-low pressure start-up device, the matching electric water pump control cabinet should also have an ultra-low-pressure start-up device, and the lower limit of the two pumps should have a certain pressure difference. Of course, according to customer requirements, design a control system that is more suitable for customer needs.
