It boasts high-performance capabilities in water extraction and pressure delivery, enabling rapid supply of large volumes of water. The system operates independently, ensuring its reliability even in challenging situations. With its lightweight and portable design, coupled with versatile functionality, the EDJ Diesel Engine Fire Pump System is suitable for various scenarios. Whether you are part of a fire department or an industrial enterprise, the EDJ Diesel Engine Fire Pump System is your indispensable rescue partner.

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.

Leakage failure in a fire pump refers to the undesirable escape of fluid, typically water, from the pump or its associated components. It is a critical issue that can hinder the performance and reliability of the fire pump system. Here are some key aspects of leakage failure in a fire pump:

Causes of Leakage: These include worn or damaged seals, gaskets, or O-rings, improper installation or tightening of connections, corrosion or erosion of pump components, and excessive vibration or misalignment.

Effects on Performance: Leakage compromises the efficiency and effectiveness of the fire pump system.

Safety Risks: Leakage failure poses safety risks to personnel and property.

Maintenance and Inspection: Regular maintenance and inspection are crucial for preventing and addressing leakage failure.

Corrective Actions: When leakage is detected, prompt action should be taken to rectify the issue.

Addressing leakage failure in a fire pump system is essential for maintaining its reliability and performance. By implementing regular maintenance practices, conducting thorough inspections, and promptly addressing any signs of leakage, the risk of failure can be minimized, ensuring the fire pump operates optimally and provides reliable water supply during critical firefighting situations.

The diesel engine fire pump unit is directly driven by the diesel engine fire pump, and it is a mechatronic equipment that can start and complete the water supply in a short time. The diesel engine pump set is driven by a diesel engine without external power supply. Diesel pumps are suitable for fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, and textiles. Especially in the case of no electricity and dissatisfaction with the grid, choosing a diesel engine-driven water pump is the safest choice.

The fire pump is mainly used to deliver water in the fire system. As an indispensable tool for the fire system, the fire pump has the characteristics of simple structure and stable performance. Due to these advantages of high performance and low energy consumption, the safety and efficiency of the fire pump are far ahead of the pipeline tools of the same purpose.

Fire pumps work by drawing water from a water source (such as a dedicated water tank or municipal supply) and pressurizing it before delivering it to the fire sprinkler system or hose lines.

The electric pump and diesel engine pump of this set of fire pump equipment use ISO pump, the jockey pump adopts CDL pump, the three fire pumps automatically start and stop, and the diesel engine pump is the backup pump. This set of fire pump equipment is not affected by the mains, can work even without electricity, and can be used in any emergency firefighting occasions.

Diesel engine fire pumps are mainly used for emergency fire fighting on ships. At the same time, it is also suitable for industrial and mining enterprises, port terminals, warehouses and freight yards and other places. Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in emergencies such as no power supply or abnormal power supply, it can also be equipped with other diesel engines as power engines according to the needs of users.
