Diesel Fire Pump Set Adapts to Different Fire Water Flow and Pressure Requirements
Diesel engine fire pump sets support flow rates of 30–9,000 GPM and pressure configurations of 3–20 bar. Pump models, diesel engine power ratings, and jockey pumps can be matched to specific fire protection system requirements, making them suitable for fire water supply projects in sectors such as industry, warehousing, airports, terminals, and petrochemicals.
The diesel engine fire pump set is a complete fire water supply system designed to meet diverse fire protection requirements. Powered independently by a diesel engine, it offers flexible configuration regarding flow rate, head, and pressure, making it suitable for industrial plants, logistics warehouses, docks, airports, petrochemical facilities, power plants, and other locations demanding high-capacity fire water supply. Featuring an integrated design, the system combines the diesel fire pump, jockey pump, control cabinet, and various accessories—such as pressure gauges, pressure sensors, check valves, gate valves, pressure tanks, common suction and discharge piping, flexible joints, and flanges—to simplify system configuration and on-site installation. Depending on specific project requirements, the main fire pump can be selected from various types—such as single-stage, end-suction, horizontal split-case (double-suction), or multi-stage pumps—to accommodate different building heights, piping network resistances, and water demand specifications. This product series offers flow rates ranging from 30 to 9,000 GPM, heads from 3 to 20 bar, and rotational speeds of 740 to 2,900 rpm (depending on configuration); power options can also be tailored to actual operating conditions, enabling the system to meet needs ranging from small-scale water supplies to large-scale fire protection networks. During standby, the jockey pump maintains network pressure with low flow and compensates for pressure drops, thereby preventing the main fire pump from starting frequently due to minor pressure fluctuations. When high-demand fire situations arise, the diesel fire pump delivers the necessary flow and pressure to the fire piping network, hydrants, and other fire-fighting equipment. As the diesel engine provides independent power and does not rely entirely on the site’s electrical grid, the system is highly valuable for applications requiring backup power. It can be equipped with an automatic control cabinet for centralized control of both the diesel fire pump and the jockey pump; integrated with pressure monitoring devices, this setup facilitates convenient operation and system management. The integrated base design allows for the unified installation of major components, resulting in a compact structure that simplifies transportation, on-site positioning, and future maintenance. The equipment can be configured using materials such as cast iron, stainless steel, or bronze—selected based on the specific medium and operational environment—to meet the durability and suitability requirements of various fire protection projects. For large-scale industrial facilities, high-rise buildings, warehousing centers, airports, ports, and petrochemical projects, fire protection systems must account for factors such as water supply flow rate, system pressure, piping network distance, and power reliability; consequently, diesel fire pump sets allow for precise parameter matching through various combinations of pump types, diesel engine power ratings, and auxiliary equipment. Users can determine specifications—including rated flow, rated pressure, head, pipe diameter, power output, and jockey pump parameters—based on actual fire protection designs, thereby creating a complete equipment package tailored to the specific piping network. With their flexible flow and pressure configurations, independent diesel power, comprehensive auxiliary components, and compact, integrated design, diesel fire pump sets provide reliable equipment solutions for fire water supply systems of varying scales.
