Diesel engine fire pumps have been widely used in fire diversion as fixed fire extinguishing equipment, especially in the case of sudden fire water supply such as lack of power supply or abnormal power supply, fire pumps equipped with units are horizontal single-stage, multi-stage special fire pumps, mainly composed of diesel engines. , fire pump, connecting device, fuel tank, radiator, battery pack, intelligent automatic control screen, etc. Diesel engine fire pump products have the characteristics of leading technology, high degree of automation, excellent performance protection function, reasonable structure, simple installation and high cost performance. At the same time, in order to meet the different needs of users and reasonable investment, the products are divided into multiple application series such as fire pumps, industrial emergency pumps, agricultural pumps, marine pumps, trailer-type mobile water pump stations, etc., which can be used together with electric fire pumps.

As the name suggests, fire pumps are used in fire protection. They are divided into different types according to different classification methods. They are fully sealed and leak-free. They are used in environmental protection, water treatment, fire protection and other departments to pump various liquids. They are created The ideal pumps for non-leakage, civilized workshops and civilized factories are similar to the pumps for fire protection systems, but the head and flow are different.

There are many types of fire-fighting equipment, fire hydrants and fire extinguishers are a common category, and there is also a category of fire pumps, which can be described as the heart of the fire-fighting system and play an important role in pressurising the water supply for the fire-fighting system. Among the many fire pump products, fire pumps can be divided into multi-stage and single-stage fire pumps.

Multi-stage pumps have high efficiency, corrosion resistance, reliable operation and other properties, strong bearing capacity of the pump body, strong resistance to overload and more sensitive start. Ltd. introduces you to the relevant features of multi-stage pumps. First of all, Shanghai Xizhiquan multi-stage pumps have a compact structure, with small spacing between parts and small volume. The equipment runs smoothly, has a long service life and produces less vibration during operation, so the practical life of the equipment is correspondingly long.

With its unique structure, the direction of the water inlet and outlet can be adjusted according to different needs, so it is suitable for various place environments. The direction of the inlet and outlet is horizontal, which reduces the number of bends in the pipeline connection, thus simplifying the pipeline connection and greatly enhancing the efficiency of the fire fighting system.

The efficient operation of the multistage pump is used in many larger, more demanding fire-fighting locations. Its role is mainly to play a role in the fire fighting pipeline system to pressurise and send water, multi-stage pumps are not only suitable for all kinds of fire fighting systems, but also for industrial drainage, high-rise building water pressure supply, long-distance water delivery, water circulation pressure and other occasions.

As usual, Fire pump system include Diesel engine pump + Electric motor pump+Jockey pump. Sometime, it just include Electric pump+Jockey pump.
Its power: 1.0 to 20kw, flow: 15-300gpm, head: 3-10bar, 50/60hz. The material: Cast iron or SS, bronze impeller.

EEJ fire pump group consists of two electric pumps + one jockey pump, the electric pump adopts XA pump.XA series single-stage centrifugal pump is the earliest single-stage single-suction centrifugal pump product launched by Better (China) Technology Co., Ltd.
This product combines the advantages of similar products in China and abroad, and is designed with excellent hydraulic model. Therefore, its excellent hydraulic performance and structural characteristics ensure that users can effectively reduce the operation cost of pumps in various applications.

Small diesel fire pump system consist of diesel engine, motor pump and jockey pump. It mainly used in warehouses, docks, airports, petrochemical, power plants, liquefied gas, textiles, ships, oil tankers, government embassies, military bases, administrative buildings, port commercial buildings, high-rise buildings, hotels, offices, hospitals, correctional institutions, nursing homes, schools and other occasions of a fire service.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little impact on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the machine body is between 85 and 95 °C. If the water temperature is too high, you can increase the opening of the ball valve, increase the heat dissipation capacity of the heat exchanger, and reduce the temperature of the engine cooling water.

The function of the diesel fire pump is very powerful. We can set the control time during use, for example: preheating in advance, pre-lubrication or timing start. The use of high technology has made some complicated and time-consuming things easier. The preheating setting in advance has greatly reduced the preparation time for rescue, allowing firefighters to rescue at the first time. In the face of disasters, time is money, time It is life.

The EDJ Diesel Engine Fire Pump System is a powerful and reliable firefighting equipment designed for fire suppression and emergency rescue operations. 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.

The engine provides the power necessary to drive the pump, allowing it to generate the high-pressure water or firefighting agent needed to combat fires.

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 biggest difference between a diesel engine fire pump and an electric water pump is that it has its own independent power supply system, which ensures the normal operation of the project without power or power supply. Its role is self-evident, and it can be said to be a great helper in fire emergency .
In terms of industrial applications, diesel engine fire pumps are widely used in emergency water supply for large-scale projects such as high-rise buildings, steel plants, chemical plants, hotels, and water works.
