In modern urban and industrial safety systems, fire pumps must deliver high pressure, reliable performance, and rapid response. The horizontal diesel-driven multistage fire pump offers robust high-pressure output and independent power, making it the ideal choice for high-rise buildings, petrochemical sites, power stations, and long-distance water supply systems.

1. High Head Output for Complex Scenarios
With a multistage centrifugal pump design, it delivers steady and continuous high-pressure water output, capable of reaching heads over 200 meters, making it perfect for high-rises, remote industrial zones, and extended piping systems.

2. Powerful Diesel Engine for Independent Operation
Equipped with globally recognized engines like Cummins, Deutz, or Perkins, these pump sets ensure reliable operation even in power outage scenarios, offering vital protection for critical areas.

3. Horizontal Structure for Smooth Running
The horizontal configuration ensures better balance and lower vibration, providing quieter and more stable operation. It’s suitable for both indoor and outdoor installations and is easy to maintain.

4. Multistage Impellers for Enhanced Efficiency
The pump uses multiple impellers in series to progressively boost water pressure, ensuring consistent and powerful delivery even to high elevations or long-distance pipelines.

5. Smart Control Panel for Easy Operation
Integrated with a user-friendly intelligent control system, featuring one-button start, auto-switching, fault alarms, and real-time monitoring to maximize system efficiency and operator convenience.

6. Multi-Level Safety Protection
Includes automatic protection for over-temperature, overload, low oil pressure, and high coolant temperature, ensuring safe operation under harsh or emergency conditions.

7. Modular Base for Quick Installation
Pre-installed on a solid steel skid, the complete unit offers compact structure and ease of transport. Installation is quick—just connect the pipework and power system.

8. UL/FM Compatibility for Export Markets
Available in UL/FM-compliant designs to meet North American and Middle Eastern fire safety standards, these pump sets are widely exported and globally trusted.

9. Corrosion-Resistant Materials for Harsh Conditions
Key components are made from stainless steel or ductile iron for superior resistance to corrosion and wear, ensuring long-term performance in humid, hot, or marine environments.

10. Customizable to Project Needs
Flexible in configuration to meet specific flow, head, and layout requirements. Custom options include engine brands, pump models, and control systems for a tailored firefighting solution.

The horizontal diesel engine multistage fire pump stands out as a reliable and versatile choice for firefighting water supply systems. With its powerful performance, flexible installation, and international compatibility, it provides essential safety assurance for both new projects and retrofitted systems.

    1. Automatic start: After the diesel engine pump unit receives a fire alarm/pipe network pressure/power failure/or other start-up signals, it can start automatically within 15 seconds and be put into full-load operation;
    2. Automatic charging: the battery can be automatically charged by the mains or diesel engine charging motor to ensure the smooth start of the unit;
    3. Automatic alarm: automatic alarm protection for diesel engine low oil pressure, high water temperature and other faults, and alarm and stop when the speed is exceeded again;
    4. Automatic preheating: keep the diesel engine in a hot standby state to ensure emergency work;
    5. Direct connection type: The diesel engine pump unit below 360kw adopts the first domestic direct connection technology between the diesel engine and the water pump through the elastic coupling, which reduces the failure points, greatly shortens the starting time of the unit, and increases the reliability and emergency performance of the unit ;
    6. Users can also request to set other alarm outputs (non-standard supply);
    7. With telemetry, remote signaling and remote control functions (non-standard supply);
    8. The equipment is powered by X6135, 12V135, 4102, 4105, 6102 and other series diesel engines. The diesel engine (with clutch) is connected with the fire pump through a highly elastic coupling to form a fire pump group. Fans, control panels (for automatic units) and other components.
    9. When it is an automatic control unit, the split diesel engine automatic control cabinet (programmable) realizes the automatic start, input and automatic switching of the system (the electric pump group is switched to the diesel engine pump group or the diesel engine pump group of this group is switched to another group. Diesel unit), automatic protection (diesel engine overspeed, low oil pressure, high water temperature, three start failures, low oil level, low battery voltage and other alarm shutdown protection) and other functions, and can also interface with the user’s fire center or automatic fire alarm device, Realize remote monitoring.
    10. In order to ensure the normal operation of the unit in an environment below 5°C, the unit can be equipped with an AC220V cooling water preheating heating device.
    11. Diesel engine fire pump can form an automatic fire water supply system with electric pump group, stabilized pump, etc.
    There are two water inlet methods for fire pumps: self-irrigation and suction. According to the requirements of fire protection regulations, it is generally self-irrigation. If the user needs to absorb two kinds of water, according to the requirements of fire protection regulations, it is generally the method of self-irrigation and water diversion. If the user needs to suck up the water inlet system, special instructions are required so that the company can provide an automatic vacuum water diversion device, but the size of the pump set has changed.
