High Efficiency Electric Fire Pump System for Building and Industrial Fire Water Supply
The high-efficiency electric fire pump system integrates a main electric pump, a jockey pump, a control cabinet, and a pressure tank; it supports various configurations regarding flow rate, head, and pump type, making it suitable for fixed fire water supply systems in buildings, warehouses, and industrial facilities.
The high-efficiency electric fire pump system is an integrated fire water supply package comprising a main electric fire pump, a jockey pump, a control cabinet, a pressure tank, and piping accessories. Utilizing a centralized structure that rationally combines key functional components, the system offers flexible configuration options based on the flow rate, pressure, and head requirements of building and industrial fire protection systems. It is suitable for applications in warehouses, docks, airports, petrochemical facilities, power plants, marine vessels, and other fixed fire water supply installations. The system employs an electric fire pump as the primary water supply unit; driven by an electric motor, it delivers fire-fighting water to the piping network at a stable flow rate and pressure. The jockey pump maintains daily network pressure; characterized by relatively low flow and high head, it compensates for pressure drops within the normal operating range, thereby preventing the main fire pump from starting frequently due to minor pressure fluctuations and ensuring a stable standby pressure. According to technical specifications, this series offers a flow range of approximately 14–2700 GPM, a head of 12–80 m, and a rotational speed of 740–2900 r/min, allowing for the selection of appropriate specifications based on specific project parameters. The main electric pump is available in various configurations—such as end-suction, horizontal split-case (double-suction), and multistage pumps—and offers material options for impellers (e.g., cast iron, stainless steel, or bronze) to suit actual operating conditions and project requirements. The system features an integrated design where major components—including the main pump, jockey pump, control cabinet, and pressure tank—are mounted on a common base. It comes equipped with accessories such as check valves, gate valves, pressure gauges, pressure sensors, common suction and discharge headers, flexible joints, and flanges, forming a complete fire water supply unit. This integration minimizes on-site connection and piping installation work while facilitating transportation, positioning, commissioning, and maintenance. The control cabinet provides automatic control for both the main fire pump and the jockey pump, incorporating protective features like overload and overcurrent protection to streamline equipment management; meanwhile, pressure gauges and sensors provide real-time system pressure data, serving as a basis for monitoring operation and adjusting parameters. Pressure tanks can be selected in specifications matching the pump unit’s head requirements—with common capacities including 25, 50, 75, and 100 liters—and configured with pressure ratings of 0.6 MPa, 1.0 MPa, or 1.6 MPa based on project specifications, ensuring a proper match between the pressure maintenance device and the fire pump assembly. In practical applications, equipment selection for building fire protection systems typically depends on factors such as building height, required fire-fighting water volume, piping network resistance, and design pressure; conversely, industrial facilities, warehouses, and large public venues may impose distinct requirements regarding continuous water supply capacity and equipment configuration flexibility. Consequently, electric fire pump systems allow for tailored configurations by adjusting parameters such as the main pump’s flow rate, head, power, and pump type, as well as the settings of the pressure-maintaining pump. The centralized layout of the integrated equipment minimizes the spatial footprint within the fire pump room, ensuring clear connections between pump bodies, control equipment, pressure components, and piping accessories, while facilitating the inspection and maintenance of key components by personnel. The electric main pump handles primary fire-fighting water delivery, the pressure-maintaining pump sustains network pressure, and the control cabinet manages equipment operation; together, these components form a coordinated fire water supply unit that meets the fundamental supply needs of fixed fire protection systems while enhancing the convenience of equipment configuration and management. Characterized by a wide range of flow and head configurations, flexible pump selection, a compact integrated structure, and robust control and pressure-maintenance capabilities, this electric fire pump system is suitable for diverse fixed fire water supply projects in both buildings and industrial facilities, providing reliable pressurized water delivery for fire-fighting piping networks.
