1. Diesel-driven system: Independent power supply, ensuring emergency response

The most distinctive feature of diesel-powered fire pumps is their ability to generate power independently, unaffected by the grid power system. The diesel engines used in ZJ-BETTER systems are sourced from renowned domestic and international brands such as Weichai, Yuchai, Cummins, and Perkins, enabling instant startup in zero-power environments to ensure water supply during emergencies. Diesel engines offer advantages such as rapid startup, stable operation, and high fuel efficiency, making them suitable for scenarios without grid power, unstable power supply, or critical infrastructure. To ensure continuous operation, the system is equipped with a large-capacity fuel tank and dual battery packs, guaranteeing over 8 hours of continuous water supply. Even in extreme conditions such as typhoons, earthquakes, or grid failures, the system can operate normally, making it a reliable emergency device that “never lets you down in critical moments.” Additionally, ZJ-BETTER customizes its diesel pump systems to accommodate different fuel types and emission standards across various regions, ensuring efficient compatibility and stable operation worldwide.

 

II. High-Efficiency Pump Components: Stable Flow Rate and Precise Head

In firefighting systems, pump performance is a core metric. ZJ-BETTER's diesel fire pumps are equipped with high-efficiency centrifugal pump components, featuring advanced hydraulic design and internal flow channels optimized through CFD simulation, ensuring exceptional operational efficiency even under high-head and high-flow conditions. The pump body structure is available in multiple configurations, including single-stage end-suction pumps, horizontal multi-stage pumps, and double-suction split-case pumps, covering a head range of 30m to 250m and a flow rate range of 20m³/h to 1500m³/h, meeting the needs of various scenarios such as high-rise buildings, tunnels, and industrial zones. The pump body is made of high-strength cast iron or stainless steel, while the impeller is made of precision-cast copper or stainless steel, offering excellent corrosion resistance and wear resistance. Notably, ZJ-BETTER employs strict dynamic balancing calibration processes to ensure stable operation, minimal vibration, and low noise levels, with overall efficiency exceeding 80%, placing it at the forefront of similar products.

 

3. Intelligent control system: automatic start-up, remote monitoring

The ZJ-BETTER diesel fire pump is equipped with a dedicated intelligent control cabinet, integrating core components such as a PLC controller, industrial touchscreen, alarm module, and sensor module to establish a complete “automatic + manual + remote” triple control system. The control system can automatically start the pump group via various trigger signals such as pressure switches, liquid level gauges, and fire alarm interlocks, ensuring automatic response without manual intervention during fire incidents; It also supports local manual buttons and remote cloud platform start/stop commands, enabling flexible control across various scenarios. The system features self-diagnosis and data logging capabilities, continuously monitoring critical parameters such as oil pressure, water temperature, voltage, RPM, and fault codes. In case of abnormalities, it automatically triggers alarms, power shutdowns, and mode switches. The communication protocol is compatible with industrial standards like Modbus and RS485, enabling seamless integration with BMS systems to achieve digital upgrades in fire management.

 

4. Skid-mounted structure: modular integration, quick installation

To facilitate rapid deployment in engineering projects, the ZJ-BETTER diesel fire pump adopts an integrated skid-mounted structure design, with the engine, water pump, control cabinet, fuel tank, battery, and other modules uniformly installed on a reinforced steel base. Wiring, testing, and commissioning are completed at the factory, and users only need to connect the pipes and power supply on-site to put it into use. The entire skid-mounted system offers advantages such as compact structure, convenient transportation, and simplified on-site construction, making it particularly suitable for overseas projects, remote areas, or projects with tight schedules. The base features standard lifting holes for easy overall transportation and rapid positioning, saving over 70% of installation and debugging time. Additionally, ZJ-BETTER offers customized skid-mounted services, such as installing soundproof enclosures, rain shelters, sliding track bases, and mobile wheels, further expanding the system's application environments.

 

5. Multiple Protection Mechanisms: Safe and Reliable Operation

Fire protection systems cannot afford any mistakes, so ZJ-BETTER has equipped diesel engine pumps with multiple safety protection mechanisms, including:

 

Low oil pressure alarm and shutdown protection

 

High water temperature alarm and automatic shutdown

 

Battery voltage below set value prevents startup  

 

Control system communication interruption automatically switches to local mode  

 

Monitoring of operational states such as low oil, idle running, and overload  

 

The control cabinet is equipped with audio-visual alarm functions and can upload abnormal data to a remote platform, enabling users to promptly identify and respond to issues. The entire system has obtained international certifications such as CE and ISO, ensuring legal and technical compliance for international projects.

 

6. Long-term operation capability: Supports 24/7 continuous operation

Traditional diesel pumps are primarily used for short-term emergency applications, while the ZJ-BETTER is specifically designed and optimized for prolonged continuous operation scenarios. The system is equipped with a large fuel tank, high-power cooling fan, and high-density radiator to ensure stable performance during continuous operation ranging from 8 to 24 hours. Engine selection is based on long-term performance curves, incorporating automatic lubrication and exhaust systems for clean emissions and effective noise control. The system demonstrates robust industrial-grade application capabilities, making it widely applicable in scenarios requiring round-the-clock monitoring, such as chemical plants, oil depots, and ports.  

 

7. Versatile Application Scenarios: Preferred Choice for Power Outages and Critical Infrastructure  

Diesel fire pumps are suitable for the following typical application scenarios:  

 

Regions with unstable power supply (e.g., Southeast Asia, Africa, remote mountainous areas)

 

Petrochemical bases (explosion-proof required areas)  

 

Ports, terminals, and coastal facilities  

 

Tunnels, elevated bridges, and underground structures  

 

Industrial and mining enterprises, oil fields, substations, and other critical infrastructure  

 

Especially in scenarios where grid power cannot be reliably supplied, diesel pumps can serve as primary firefighting equipment; in environments where grid power is available, they are often configured as “standby pumps” to ensure comprehensive system redundancy and safety.

 

8. Compliant with international standards, comprehensive export support
