Diesel engine fire pumps are relatively common in life, and their performance requirements are relatively high. In ordinary use, more attention should be paid to maintenance, so as to prolong the service life of the pump. Because diesel fire pumps are not omnipotent, there will be some problems in daily use, so when choosing equipment, we must pay attention to whether the quality of the equipment meets the national standards. As fire equipment, all kinds of equipment must be To ensure performance, avoid affecting use in disaster situations and delaying rescue.

1. Check the system pressure and increase if necessary.
2. Check the seals and gaskets for wear and replace if needed.
3. Check the pipe joints for any leakage and repair if needed.
4. Replace any worn or damaged parts.
5. Check the valves for any leakage and repair if needed.
6. Check the suction and discharge lines for any obstruction and clear if necessary.

EDJ series fire pump set consists of electric pump + diesel pump + jockey pump and all accessories.
The three pumps are automatically started and stopped. When the jockey pump detects that the electric pump cannot operate normally, the diesel engine pump will start automatically. Can also be used, the fire pump set is widely used in various emergency firefighting occasions.

This diesel fire pump set consist of diesel fire pump, jockey pump and accessories. It is used for warehouses, docks, airports, petrochemical, power plants, liquefied gas, textiles, ships, oil tankers and other occasions of a fire service.

The fire pump is mainly a kind of pump equipment used for fire emergency, and its function is to transport the water source to the fire scene for fire extinguishing. In life, fire pumps are widely used in various buildings, such as factories, docks, warehouses, ports and other places, and are important equipment for fire emergency.

In areas with limited access to technical support and specialized maintenance services, maintaining fire pumps can be challenging. These pumps require regular inspections, testing, and maintenance to ensure they function correctly in an emergency. In remote or underserved areas, finding qualified technicians and replacement parts can be difficult, leading to longer downtime and increased risk of system failure. To mitigate these challenges, fire pump systems in such locations are often designed with redundancy and built-in diagnostics to facilitate remote monitoring and troubleshooting. Training local staff to perform basic maintenance and leveraging online resources for support can also help ensure that fire pumps remain operational even in areas with limited technical support.

At the same time, it can be equipped with low-voltage, high-voltage and explosion-proof motors with different protection levels according to the user’s use environment and conditions. It is characterized by simple operation and maintenance, low noise, and less equipment requirements.

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.

Yes, fire pumps in high-rise buildings must account for increased pressure requirements and vertical lift. Proper placement, redundancy, and access for maintenance are also critical in these applications.
