In modern fire protection systems, rapid response to fire incidents is crucial for safeguarding life and property. The Pressure Stabilization and Dual-Function Pump System integrates powerful pressure regulation with dual power sources to ensure that the fire protection system quickly responds and maintains a continuous, stable water supply during emergencies.

This pump system is designed with two power sources—an electric motor and a diesel engine. When the primary power source fails, the diesel engine automatically starts, ensuring uninterrupted operation of the fire protection system even during power outages. Its pressure stabilization system automatically adjusts pressure during operation, ensuring stable water flow for fire suppression and preventing water interruptions due to insufficient or fluctuating pressure, ultimately improving firefighting efficiency.

The intelligent control system further enhances the efficiency of the pump system, allowing users to monitor the system’s status in real-time through a touch panel. The system is easy to operate, and any malfunction is quickly detected and alarms are triggered, activating backup systems to effectively prevent emergency issues caused by system failure.

This pump unit is ideal for applications in high-rise buildings, industrial zones, storage facilities, and other locations with high reliability requirements for fire protection, ensuring that the fire pump can be immediately activated and continue to supply water in any emergency.

High-lift diesel fire pumps are renowned for their powerful power, independent operation, and high-pressure water supply, making them an ideal choice for fire protection systems in industrial plants, high-rise buildings, and petrochemical bases. They offer advantages such as automatic control, energy conservation and environmental protection, and high-temperature and corrosion resistance, ensuring stable operation during power outages and extreme environments, providing continuous and efficient fire water support.

Fire pumps are part of the applied water supply and are powered by electricity, diesel. They activate when the pressure in the fire sprinkler system drops below a certain level and provide a flow of water to the sprinkler system at very high pressure, which is then discharged onto the fire.

The dual-power fire pump is driven by a diesel engine. When the power grid cannot meet the requirements, the diesel engine can be used to drive the water pump to ensure that the unit can reach the running state.
