It is suitable for sprinkler and fire hydrant systems, and is easy to install and maintain, providing reliable fire water supply for various engineering projects.
This horizontal, single-stage, end-suction fire pump is a stable and efficient building water supply device, specifically designed as a core power unit for modern building fire protection systems. It features a horizontal end-suction structure and a single-stage centrifugal hydraulic design, achieving efficient power transmission through direct motor drive. This ensures stable operation while effectively reducing mechanical and energy losses, maintaining excellent head and flow output performance under rated conditions. This product is widely used in fire water supply systems for high-rise buildings, commercial complexes, industrial plants, warehousing and logistics centers, hospitals, schools, and public infrastructure. It can serve as a core power unit for automatic sprinkler systems, fire hydrant systems, and fire pressure stabilization and water supply systems, providing continuous and reliable water supply support in critical moments. The pump body is integrally cast from high-strength cast iron, resulting in a robust and pressure-resistant structure with excellent impact resistance and mechanical strength. Internal flow components undergo precision machining and flow channel optimization to effectively reduce hydraulic losses and improve overall efficiency, ensuring a smooth and stable flow path within the pump chamber. This allows for energy consumption control while maintaining high flow output. The single-stage impeller is designed using a scientific hydraulic model and dynamically balanced to reduce operating vibration and noise, extend the service life of bearings and seals, and ensure stable performance even under long-term operation and frequent start-stop conditions. The end-suction design aligns the water inlet with the pump shaft axially, with the outlet located at the top of the pump body, facilitating piping layout and system connection. Standard flange interfaces conform to engineering installation specifications, allowing for quick connection to fire protection piping systems, shortening the construction cycle and reducing installation difficulty. The motor is a high-efficiency, energy-saving, fully enclosed, air-cooled motor with excellent insulation and heat dissipation performance, meeting the dual requirements of long-term standby and emergency continuous operation of fire protection systems. It starts quickly and reaches rated speed in the event of a fire, ensuring rapid water pressure increase to design requirements. The pump shaft is made of high-strength alloy steel and precision-machined, combined with high-quality rolling bearing components to reduce frictional resistance and axial movement, improving transmission efficiency and mechanical stability, resulting in smoother and more reliable operation. The mechanical seal system features a wear-resistant and high-temperature-resistant design, maintaining excellent sealing performance even under high pressure, preventing leaks from affecting system safety. This horizontal, single-stage, end-suction fire pump boasts outstanding hydraulic performance, with a wide performance curve coverage. Appropriate models can be selected based on different building sizes and fire protection design parameters, achieving precise matching of flow rate and head to meet diverse needs from small and medium-sized buildings to large-scale projects. During daily operation, the equipment can be used as a pressure-stabilizing water supply pump. Through linkage with pressure sensors and the control cabinet, automatic start-stop control is achieved, promptly replenishing water to maintain system stability when the pipeline pressure drops slightly, reducing wear caused by frequent main pump starts and extending the overall lifespan of the fire protection system. To ensure the equipment’s adaptability to complex environments, the entire surface is treated with industrial-grade anti-corrosion spraying, possessing excellent oxidation and corrosion resistance, allowing for long-term use in humid machine rooms or semi-open environments. The base structure is robustly designed, allowing for easy positioning during installation. It operates with low vibration and noise, making it suitable for building projects with high environmental noise requirements. Before leaving the factory, the product undergoes rigorous performance testing, pressure testing, and continuous operation testing to ensure that all parameters meet design standards, guaranteeing reliable start-up and continuous water supply in critical moments. This equipment can also be combined with electric main fire pumps and diesel engine fire pumps to form a complete fire pump system, achieving multi-level control and redundancy design, improving system safety, and maintaining water supply capacity even in the event of main power failure or emergency. By optimizing the impeller diameter and motor power matching, the equipment achieves high-efficiency operation under rated conditions while maintaining energy-saving performance during low-load operation, reducing overall operating costs. The end-suction structure facilitates daily maintenance, with simple disassembly and assembly. The rational layout of key components allows maintenance personnel to quickly inspect or replace parts, reducing downtime and improving equipment availability. This horizontal single-stage end-suction fire pump can meet the stringent pressure requirements of end sprinkler heads and fire hydrants in high-rise buildings, and can achieve stable long-distance water supply in industrial plants and large warehousing centers, ensuring wide coverage and sufficient pressure of fire water sources. Its stable operating characteristics effectively avoid water hammer caused by water pressure fluctuations, protecting the safety of pipe networks and valve systems. With its efficient hydraulic design, robust structural materials, and reliable drive system, this equipment ensures fire safety while also being energy-efficient and cost-effective, providing a stable and reliable water supply solution for building fire protection engineering. Whether in new construction projects or upgrades of existing systems, this horizontal single-stage end-suction fire pump is an ideal choice due to its compact structure, stable performance, and long service life. It continuously delivers strong water pressure in critical moments, building a safe, reliable, and efficient fire water supply system for buildings and industrial sites.
