Product Overview

The XBC-SOW Diesel Engine Fire Pump Set is a high-performance dual-suction fire water supply system designed and manufactured in strict accordance with the GB 6245-2006 and NFPA 20 standards. It is specially designed for emergency firefighting applications when the main power supply is unavailable, ensuring automatic start-up and continuous water delivery during power outages.

Model Designation

XBC SOW单级双吸柴油机消防泵T

Key Features

  1. The XBC-SOW Diesel Engine Fire Pump Set is the core pump model for the system, suitable for high-pressure environments such as high-rise buildings.
  2. The unit adopts a modular design for easy installation and maintenance, ensuring efficient and stable operation of the system.
  3. Pneumatic pumps provide stable pressure output, suitable for low-maintenance and high-efficiency applications.

Engineering Summary

The XBC-SOW Series integrates a diesel engine, horizontal dual-suction fire pump, and automatic control system. The system operates fully automatically via preset pressure logic. When the pipeline pressure drops below the set value, the system automatically starts, and stops when the main power supply is restored, ensuring stable and reliable firefighting pressure.

Applications

The XBC-SOW Diesel Engine Fire Pump Set is suitable for industrial and municipal fire water supply systems, providing a reliable emergency water source during power failures, meeting the requirements for continuous water supply and system reliability in fire protection applications.
