The Smart-Controlled Diesel-Electric Firefighting System is engineered to meet the high standards of fire protection required in industrial and commercial buildings. By integrating both electric and diesel power sources, it ensures a rapid response in any emergency situation. The system incorporates an advanced smart control module that enables automatic startup, real-time monitoring, fault alarms, and remote management, significantly enhancing safety and ease of operation. Whether installed in high-rise urban structures, industrial parks, or commercial complexes, this system reliably delivers a stable and efficient fire water supply, offering round-the-clock protection and making it the ideal solution for building a modern, intelligent fire protection network.

Fire pump sets are often required when the local water system cannot provide sufficient pressure to meet the design hydraulic requirements of the fire sprinkler system. This typically occurs in multi-story buildings or systems that require relatively high terminal pressures at fire sprinklers in order to release large volumes of water, such as storage warehouses. A fire pump is also required if the water supply is provided from above-ground or underground storage tanks.

There are many types of fire-fighting equipment. Fire hydrants and fire extinguishers are the most common types. The other is the fire pump, which is the heart of the fire-fighting system and plays an important role in pressurizing the fire-fighting system. Among the numerous fire pump products, fire pumps can be divided into multi-stage and single-stage fire pumps.

Horizontal split case pumps offer high efficiency, low noise, and easy maintenance, making them ideal for firefighting water systems in high-rise buildings, municipal projects, and industrial facilities, ensuring reliable and energy-efficient performance.

This is a set of EDJ fire pump set, which consists of electric pump + diesel pump + jockey pump. The three pumps are automatically started and stopped. When the joceky 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

Users should be trained in the proper operation of the pump and follow all safety guidelines. It’s important to wear appropriate personal protective equipment, ensure proper ventilation, and be aware of potential hazards.

Fire pumps are classified into various types based on their specific applications and operational characteristics. The common classifications of fire pumps include:

Horizontal Split Case Fire Pumps: These pumps have a horizontally split casing, which allows easy access to internal components for maintenance and repairs. They are typically used in large-scale fire protection systems, such as industrial facilities, commercial buildings, and high-rise structures. Horizontal split case pumps are known for their high flow rates and can handle a wide range of pressures.

Vertical Turbine Fire Pumps: Vertical turbine pumps have a vertical shaft and are designed to operate with submerged impellers. These pumps are commonly used in water sources such as wells, rivers, or lakes. Vertical turbine fire pumps are ideal for locations where space is limited, as they have a small footprint. They are also suitable for applications that require high pressures but lower flow rates.

Vertical Inline Fire Pumps: Vertical inline pumps have a vertical design with the motor located above the impeller. These pumps are compact and space-saving, making them suitable for installations where floor space is limited. Vertical inline fire pumps are commonly used in commercial and industrial applications, such as office buildings, hospitals, and manufacturing facilities.

End Suction Fire Pumps: End suction pumps have a single impeller mounted on the end of the shaft. They are widely used in various applications, including fire protection systems. These pumps are known for their simplicity, ease of maintenance, and cost-effectiveness. End suction fire pumps are typically used in smaller buildings, residential properties, and light commercial applications.

Multistage Fire Pumps: Multistage pumps consist of multiple impellers arranged in series. Each impeller adds pressure to the water, allowing these pumps to deliver high pressures. Multistage fire pumps are suitable for applications that require high-pressure delivery, such as high-rise buildings, industrial plants, and sprinkler systems with demanding pressure requirements.

Diesel-Driven Fire Pumps: Diesel-driven fire pumps are powered by diesel engines, providing a reliable source of power in situations where electricity may be unavailable or unreliable. These pumps are commonly used in remote locations, off-grid areas, and critical infrastructure where continuous operation is essential. Diesel-driven fire pumps are known for their durability and ability to deliver high flow rates and pressures.

It’s important to note that these classifications are not exhaustive, and variations of fire pumps exist within each category. The choice of fire pump classification depends on factors such as system requirements, available space, flow rates, pressure requirements, and power sources. Consulting with fire protection experts or system designers can help determine the most suitable fire pump classification for a specific application.

Fire pump systems are comprised of various components, each playing a critical role in ensuring their proper function. Some of the key components include:

Fire Pump: This is the heart of the system, responsible for pressurizing the water and sending it to the fire protection devices.

Controllers: Controllers monitor the system, automatically starting the pump in response to a fire alarm signal and providing system status information.

Suction and Discharge Piping: Properly designed piping is essential for efficient water flow. Suction piping brings water to the pump, while discharge piping carries it to the fire protection devices.

Pressure Relief Valves: These safety valves release excess pressure to prevent damage to the system.

Valves: Various valves control water flow within the system, allowing for isolation, testing, and maintenance.

These components work in concert to provide reliable water distribution in case of a fire.

When we buy fire pumps, we all encounter this situation: the products we buy fail to meet the parameters required by ourselves, or exceed the parameter range required by ourselves, resulting in that they cannot be used. Or the product is not the type you want, which shows the importance of product testing.

The double-suction fire pump has the characteristics of high lift and large flow, and is widely used in fire fighting. The impeller of this pump type is actually a combination of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is horizontally opened, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable.

The fire pump set adopts ISW pump, which saves cost and is reasonably priced. This series of fire pump sets are suitable for fire protection occasions such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas, textiles, ships, and oil tankers.
