Product Overview
Product Introduction of XBC series diesel engine fire-fighting pump
XBC series diesel engine fire-fighting pump group is a new-style fire-fighting equipment developed in accordance with GB6245-98 and NEPA20 standard, and upon the fitted fire-fighting pumps (single-stage single-suction type, single-stage double-suction type and sectional multistage type), can be divided into XBC-IS, XBC-S and XBC-D three sub series. The equipment has a wide range of pressure and temperature and can be used for almost every occasion necessary for fire-fighting.
The diesel engine fitted with the equipment is an excellent product domestic or imported, features good starting performance, strong overload capacity, compact structure, easy maintenance and use and high degree of automation. The equipment is really a fire-fighting one advanced and reliable in performance.

Fire pump room installed with units should be as close as possible to the pool, the water intake pipeline of the water part should be as short as possible, and the elbows should be as few as possible to reduce the resistance of the water intake. And ensure that the unit space is spacious enough for the operation and maintenance of the unit. Pump house should have hoisting equipment and thermal insulation measures to ensure that the lowest temperature of pump house (> 5 Celsius) is prepared before the pump is installed, and that the foundation can bear the weight of the pump group.

Diesel fire pumps are available in various configurations, including horizontal split-case, vertical turbine, and end-suction pumps. Each type has its advantages and is suitable for different applications based on factors such as space limitations, flow requirements, and installation preferences. Consulting with a qualified engineer or fire protection specialist can help determine the most appropriate type of diesel fire pump for a specific application.

The Horizontal Multistage Pump is an exceptional engineering solution that offers high performance and reliability for fluid handling applications. With its unique multistage impeller design, it delivers efficient and incremental pressure boosting for high-pressure and high-flow scenarios. Whether used in water supply systems, industrial processes, irrigation, or building cooling, this pump ensures stable water pressure and flow.

Fixed fire water supply equipment can use fire pumps driven by electric motors, or fire pumps driven by diesel engines. The international standard name of diesel engine fire pump set is “engineering diesel engine fire pump set”. It uses diesel engine as power to drive fire water pump, and outputs pressurized water or air foam mixture for fire extinguishing work.
When dual power supplies are required or in order to further improve reliability, fire water supply equipment often adopts fire pumps driven by diesel engines. After the various components of the diesel engine fire pump set have passed the strict certification test and passed the test, their reliability is much higher than that of the electric motor fire pump set.

The biggest difference between the diesel engine fire pump and the electric water pump is that it has its own independent power supply system – the storage battery. Therefore, the start and operation of the diesel engine fire pump can be completely separated from the mains.
The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference. Of course, we can also design a control system that is more suitable for customer needs according to customer requirements.

Overview of diesel engine fire pump products: The fire pumps used in the complete diesel engine fire pump unit can be the IS series single-stage type, S series new single-stage two-stage type, and D type series segment multi-stage type produced by our company. The diesel water pumps used in this series of equipment are made of domestic high-quality products. They have the characteristics of good starting characteristics, strong overload capacity, compact structure, convenient maintenance, simple use and high degree of automation. They are advanced and reliable fire fighting equipment.

All places need to be equipped with fire-fighting facilities, and fire pumps are the water intake equipment for fire-fighting 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 systems. supply. In case of power failure, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

Fire pumps are used in the equipment of the fire protection system. Their function is to increase the pressure to supplement the water source, so as to achieve the purpose of extinguishing the fire. Moreover, the equipment adopts high-tech means and introduces advanced technology, which has incomparable advantages over other products.

By providing reliable fire protection capabilities, firefighting pumps play a crucial role in enhancing community resilience and safety. They help prevent fires from spreading and minimize the damage caused by fires when they occur, thereby reducing the risk to residents, businesses, and infrastructure. Additionally, well-maintained firefighting pumps can improve a community’s ability to respond effectively to emergencies and mitigate the impacts of disasters.

A split case pump is a centrifugal pump that features two single suction impellers or a double suction supported between bearings. The casing is split axially with opposing suction and discharge flanges. This allows for easy maintenance on the pump.

The Diesel Engine End Suction Fire Pump set is suitable for emergency firefighting scenarios, particularly ideal for high-rise water supply, building firefighting, central air conditioning water circulation, industrial process system circulation, cooling systems, boiler water supply, industrial water supply and drainage, water plant supply, irrigation in plantations, and more.

Fire pumps typically use two driving forces, including a diesel engine and an electric motor. Diesel engines are commonly used in portable fire pumps and light duty firefighting. Electric motors are the most widely used driving force for fire pumps and are both efficient and convenient. In 2016, electric fire pumps accounted for around 50% of the entire fire pump market. Fire pumps can be used in industrial, commercial, field emergencies and more.

Since the operation of the electric water pump is inseparable from electricity, and the power supply is often cut off at the scene of a fire accident or the power supply is automatically closed due to the fire, even if we are equipped with a dual power supply switching device, it is really impossible to ensure that the power grid must be normal when the fire alarm signal comes.
Therefore, starting and running a diesel engine fire pump completely disconnected from the grid becomes the preferred equipment for backup fire protection facilities! The driving power of diesel engine fire pumps is completely different from that of electric water pumps, so their daily protection and treatment are also different in many places! The characteristics of diesel engine fire pump: The biggest difference between diesel engine fire pump and electric water pump is that it has its own independent power supply system – storage battery. Therefore, the start and operation of diesel engine fire pump can be completely separated from the mains.
