Compact Diesel Fire Pump Equipment for Various Fixed Fire Water Supply Systems
The compact diesel fire pump unit features an independent diesel power source and an integrated base design, combining the fire pump, jockey pump, and control system. It supports various flow rate and head configurations and is suitable for fixed fire water supply systems in buildings, warehouses, and industrial facilities.
The compact diesel fire pump unit is a complete fire water supply system driven by an independent diesel engine. It primarily consists of a diesel fire pump, a jockey pump, a control system, piping accessories, and a common base. By effectively integrating these functional components, the unit minimizes its footprint while ensuring reliable fire water supply performance; it is suitable for fixed fire water supply systems in buildings, warehouses, industrial plants, docks, airports, commercial facilities, and other locations. Driven by a diesel engine, the main fire pump does not rely on a fixed electrical grid as its sole power source. The engine and pump model can be matched to specific project requirements—such as flow rate, head, pressure, and installation conditions—offering a viable solution for systems requiring independent power support. The unit features an integrated base design that consolidates the diesel engine, fire pump, and auxiliary components, resulting in a compact structure that facilitates transportation, on-site positioning, and piping connections while reducing the space typically required for installing multiple separate units. Depending on project parameters, the main fire pump can utilize various configurations—such as single-stage, end-suction, horizontal split-case (double-suction), or multi-stage pumps—and can be fitted with impellers made of cast iron, stainless steel, or bronze to meet specific flow and pressure requirements. According to technical specifications, this series offers flow rates of approximately 30–9000 GPM, heads of 3–20 bar, and speeds of 740–2900 rpm; power ratings can be configured to suit the equipment specifications, covering the water supply needs of fixed fire protection systems of various scales. The jockey pump serves as an auxiliary pressure-maintenance device; typically characterized by low flow and high head, it compensates for minor pressure drops during normal operation, maintains system pressure, and prevents the main fire pump from starting frequently due to slight pressure fluctuations, thereby stabilizing the system’s pressure management. The control system provides centralized control for both the diesel fire pump and the jockey pump, incorporating protective features such as overload and overcurrent protection. It also monitors system status via pressure gauges and sensors, simplifying equipment operation, commissioning, and routine maintenance. The entire system can be configured—based on specific project requirements—with check valves, gate valves, pressure vessels, pressure gauges, flexible joints, flanges, and common suction and discharge piping. This integrates key functional components into a complete fire-fighting water supply unit, thereby reducing on-site installation workload and ensuring a neat, organized equipment layout. A key feature of the product is its compact structure; it allows for the efficient arrangement of the power unit, pump assembly, control system, and piping components within the limited space of a fire pump room, maximizing space utilization while meeting fire-fighting water supply demands. Furthermore, the centralized layout of major components facilitates inspection of the engine, pump, valves, piping, and controls, simplifying routine maintenance and operational management. The system can be tailored to various building scales and fire protection design requirements by adjusting parameters such as pump type, diesel engine power, flow rate, head, and pipe diameter, making it adaptable to a wide range of fixed fire-fighting water supply applications. With features including independent diesel power, a compact integrated structure, flexible parameter configuration, auxiliary pressure stabilization, and centralized control, this diesel fire pump unit delivers reliable water delivery for diverse fixed fire protection systems. It effectively balances installation space constraints with operational and maintenance needs, serving as an ideal integrated water supply solution for industrial facilities, warehouses, commercial buildings, and other fire protection projects.
