EDJ Fire pump set

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.

Prior to installation, fire sprinkler systems are hydraulically calculated to ensure adequate water flow and that the system can reliably suppress a fire until fire crews arrive. When it is determined that there is insufficient flow from a municipal supply for the system to function properly, a fire pump is installed. The fire pump activates when the sprinkler system pressure falls below a certain threshold as a result of sprinkler head operation. To maintain the required operating pressure of the sprinkler system, the fire pump draws additional water from the municipal water supply or on-site storage tanks. Due to the size of piping systems and pressure loss, fire pumps are frequently required in high rise construction and large area buildings.
