The EEJ Pump Set is designed according to the customer’s specifications which is including 2 electric pumps, 1 jockey pump and 1 control panel.

1. The function of the diesel fire pump is very powerful. We can set the control time during use, such as: preheating, pre-lubricating or timing start. The use of high-tech has made some complicated and time-consuming things easier in the past. The preheating setting greatly reduces the preparation time for rescue, allowing firefighters to rescue the first time. In the face of disasters, time is money and time. is life.
2. The head and flow can be controlled by adjusting the speed of the engine, and the height and size of the water flow become easier to control. When the nozzle is in a stable state, by controlling the engine, we can accurately spray the water source at the fire point to extinguish the fire, which also reduces the difficulty of rescue for firefighters.

A typical firefighting pump system consists of the pump itself, intake and discharge hoses, nozzles, strainers or filters to prevent debris from entering the pump, and sometimes additional accessories like foam injection systems for enhanced fire suppression capabilities.

In large industrial complexes, fire pumps are vital in supporting firefighting efforts by providing a reliable water supply to extensive fire protection systems, including sprinklers, hydrants, and hose reels. These facilities often have complex layouts and multiple hazards, requiring robust fire pumps capable of delivering high water flow rates and pressure over long distances. Fire pumps in these settings are typically part of a comprehensive fire protection strategy that includes redundant pumps, emergency power supplies, and advanced control systems to ensure continuous operation even if one component fails. By delivering a consistent and adequate water supply, fire pumps help ensure that firefighting efforts are effective, minimizing damage and protecting both personnel and assets.

The fire-fighting dual-power water supply equipment is suitable for all kinds of emergency backup pumps. When the mains is normal, the electric pump set is put into work. When the power supply fails and the electric fire pump cannot be put into use normally, the diesel engine fire pump set can be automatically put into operation to ensure firefighting. Fire extinguishing is carried out normally, and the diesel engine fire pump set is equipped with various automatic functions to meet the requirements of national standards, ensuring that the equipment is in a normal standby state for a long time, and can be put into fire fighting work at any time.

Fire pumps are water intake equipment for fire facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between them is that electric fire pumps require power system supply. In the event of a power failure, the diesel engine fire pump can start at any time to compensate for the original position of the electric fire pump.

Key components include the pump itself, the engine or motor, an intake system, a discharge system, and various safety features such as pressure relief valves.

Diesel engine fire pumps are suitable for use in fire water supply environments with high head and high flow rate or as backup fire water supply pumps. The reason is that the diesel engine has strong power and can be used with large flow fire deep well pumps, and the diesel engine fire pumps have the characteristics of self-starting when power is off. Emergency water supply is available, so diesel engine fire pumps are favored.

If the fire pump is corroded, it should be inspected by a qualified professional. Depending on the extent of the corrosion, the pump may need to be repaired or replaced. The professional may also need to inspect the entire system for any other potential issues. In some cases, a fire pump may need to be replaced if the corrosion is severe and cannot be repaired.

Spectrum range: fire pump can use a single-stage end suction pump,a combination of multistage single-suction pumps, single-stage double-suction pumps and other kinds of pumps, pump or more kinds of parallel flow, wide pressure range.
Automatically. when the engine fire pump receives a valid signal fire, remote control start signal when the unit will start automatically; when the fire pump motor supply failure or lack of signal phase, the unit will automatically standby. Diesel fire pump start 10s, if not start running, stop 10s, and then restart. The unit will automaticaly repeat three times.
Alarm System: repeatedly failed to start alarm, low diesel engine oil pressure alarm, ultra-high temperature alarm diesel engine, diesel engine speed alarm, low battery alarm, charging failure alarm, an alarm indicating a lack of fuel.
kinds of ways to start signal fire started, manually start or remote start.

The EDJ fire pump unit is suitable for various fire boosting and pressure stabilizing pump occasions; various villas, residential areas and other fire protection systems; industrial and civil building fire protection systems; suitable for various oil depots, oil loading and unloading docks, logistics parks and other fire protection levels demanding places.

The Fire Pressure Stabilization Equipment, coupled with the CDL Vertical Multistage Fire Pump, offers a comprehensive solution to elevate fire safety measures. This powerful combination ensures a consistent water pressure for effective fire suppression. By incorporating pressure stabilization technology, this system guarantees an uninterrupted fire water supply, efficient water distribution, and reliable operation of fire hydrants and sprinkler systems. With advanced infrastructure and the ability to maximize firefighting capabilities, this configuration significantly enhances overall fire safety standards. Investing in fire pressure stabilization equipment is a proactive step towards ensuring superior fire protection and providing peace of mind in critical situations.

Fire pump test headers allow for the controlled flow of water during routine testing. They are used to verify the performance of the pump, pressure switches, and other components, providing a standardized method for testing without affecting the main fire protection system.
