EDJ Dual-Power Fire Pumps: Redefining Fire Safety Standards

The diesel engine fire pump set has the characteristics of good starting performance, strong load capacity, compact and effective structure, convenient maintenance, simple and reliable use, etc. The generator set has maintenance functions such as speed limit, low oil level, repeated failed starts, high temperature, low oil level, and low battery voltage. At the same time, it can be connected with the customer’s automatic fire alarm system or the centralized control cabinet of fire-fighting facilities to establish a real-time monitoring function.

Maintaining fire pumps and jockey pumps is essential for ensuring their reliable operation in an emergency. Best practices for maintenance include regular inspection and testing of the pumps, checking for leaks, corrosion, and wear on components, and ensuring that all electrical connections and control systems are functioning correctly. It is also important to perform routine flow tests to verify that the pumps can deliver the required water flow and pressure as specified by design standards and regulatory codes. Lubrication of moving parts, replacement of worn-out seals and gaskets, and calibration of pressure sensors and alarms should also be part of a comprehensive maintenance program. Additionally, keeping detailed records of all inspections, tests, and maintenance activities helps track the condition of the pumps over time and identify potential issues before they lead to failure. Regular training for personnel on the operation and maintenance of fire pumps further enhances system reliability and readiness.

Fire pressurized and stabilized water supply equipment can make the fire water supply pipeline system the most unfavorable point always maintain the fire pressure, and the use of air pressure water tank always stored in the 30 seconds of fire water, to ensure the fire pump before the operation of the fire spray water; The device uses the operating pressure set by the air pressure water tank to control the operating condition of the pump and achieve the function of pressurization and pressure stabilization.

Diesel engine fire pump has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. This diesel engine pump set can transport clean water or other liquids whose physical and chemical properties are similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump’s flow parts, sealing form and adding a cooling system.

Diesel engine fire pump is a common and necessary facility. Only when the fire signal comes, and the electric water pump fails or the power supply is cut off, the diesel engine fire pump will automatically start. Diesel engine fire pump is installed together with electrical instruments, with complete functions, compact structure, automatic fault alarm, receiving start signal, and can automatically complete the start-up procedure and fast full-load operation. , Enough to ensure that the diesel engine fire pump is started in a low temperature environment, the whole system of the diesel engine fire pump is safe, reliable, and easy to use.

Air in a centrifugal pump usually occurs because of a suction issue. Air can be introduced into the pump either because of a piping issue, such as low water level, or an internal issue, such as incorrect impeller clearance. To prevent air from entering the inlet pipe and pump body, the piping should be checked to ensure it is properly sealed and the pump should be regularly inspected to check impeller clearance.

Fire pumps are part of the water supply to a fire sprinkler system and are powered by electricity or diesel. The pump inlet is either connected to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). This pump provides higher pressure water flow to sprinkler system risers and hose risers.
Our factory can manufacture NFPA20 compliant fire pumps.
Fire pumps can function with electric motors or diesel engines, and if local building codes require electricity independent of the local grid, pumps using electric motors can use the installation of an emergency generator when connected through a transfer switch listed.

500gpm, 5bar fire fighting pump, export to Greece.Duty pump is electric fire pump, diesel engine fire pump as standby.

Outline the specific installation requirements for fire pumps, such as space considerations, accessibility, and adherence to NFPA 20. Explain how correct installation ensures reliability and ease of maintenance, and discuss the importance of proper alignment, securing power sources (for electric pumps), and ventilation (for diesel pumps).

EDJ series fire pump sets are mainly installed in fire trucks, fire extinguishing systems or other fire fighting facilities, and are special pumps used to transport liquids such as water or foam solution.
The fire pump set includes a main pump connected to the electric motor, a backup pump connected to the diesel engine, jockey pump, pressure vessel, controller for manual or automatic operation of the system and standard accessories mounted on the base.

The electric fire pump set is an important fire pump equipment, usually in a horizontal state. Each pump group is composed of five parts: front pump, electric motor, hydraulic coupling, main feed water pump, lubricating oil device (including lubricating oil cooler and working oil cooler. In normal state, two sets are running, one There are two standby pumps, and any feedwater pump set can be used as a standby pump. When one of the two running pumps stops due to an accident, the standby pump will be put into operation automatically.

The advantage of its product is that when a fire occurs, the power supply fails, and the electric fire pump set cannot be put into use normally, the diesel engine fire pump set can be put into operation automatically to ensure the normal fire fighting. Compared with the electric fire pump set, it does not need long-term investment in power supply, saving the mains power supply transformer and normal expenses. Diesel engine fire pumps are equipped with various automatic functions to meet customer requirements, ensure long-term normal standby status of the equipment, and put it into fire fighting work at any time. The diesel engine fire pump set is also suitable for various emergency backup pump occasions.

3. Control panel: Automatically control the water pump with overload and overcurrent protection.
4. Accessories: suction pipe, discharge pipe with flange, battery, gate valve, check valve, flexible expansion joint, pressure switch, pressure gauge, base, etc

Jockey pumps are a vital component in maintaining the pressure within a fire protection system. Their primary role is to keep the system’s pressure within the desired range. When there’s no fire event, the jockey pump operates to counteract any pressure losses due to minor leaks or gradual pressure decreases in the system.

By maintaining system pressure, jockey pumps ensure that the primary fire pump is ready to respond quickly and efficiently when a fire occurs. This pressure stability is crucial for the proper functioning of the entire fire protection system, allowing for immediate water flow to sprinklers or hose connections.

Fire pumps are necessary to maintain adequate water pressure for firefighting, especially in high-rise buildings, large industrial facilities, or areas with insufficient water supply.
