Vertical Single-Stage Centrifugal Fire Pump for Stable and Efficient Fire Water Delivery
The vertical single-stage centrifugal fire pump features a compact vertical design, delivering stable and efficient fire-fighting water supply. It supports a wide range of configurations regarding flow rate, head, port size, and power, making it suitable for use in buildings, industrial facilities, and fixed fire-fighting water supply systems.
The vertical single-stage centrifugal fire pump is designed for fixed fire water supply systems. Driven by an electric motor, the pump shaft and impeller rotate at high speed, converting mechanical energy into the pressure energy of the water flow to ensure stable pressurization and delivery of fire-fighting water. Featuring a vertical single-stage centrifugal structure and a compact layout, the pump body is directly connected to the drive motor; this design minimizes the equipment’s footprint while meeting performance requirements, making it suitable for fire pump rooms in residential and commercial buildings, industrial plants, warehouses, and other fixed fire water supply installations. To meet specific project requirements, this series offers various configurations regarding flow rate, head, inlet/outlet diameter, and motor power. Official specifications indicate a diameter range of 25–500 mm, flow rates of 1–300 L/s, a head range of 0.15–1.6 MPa, power ratings of 0.75–160 kW, and rotational speeds of approximately 1500–2900 r/min, allowing for optimal selection based on factors such as fire network demand, building height, pipeline resistance, and terminal pressure requirements. During operation, water entering the pump body gains the necessary pressure and flow velocity through the centrifugal action generated by the rotating impeller; the relatively simple structure and clear hydraulic flow path facilitate stable operation. The vertical configuration effectively utilizes vertical space in the pump room, making it highly adaptable for projects with limited installation space, while the compact design helps reduce piping distances and the space required for on-site installation. Depending on the medium and project specifications, components in contact with the fluid can be configured with materials such as cast iron, stainless steel, or bronze impellers, offering flexible material choices for diverse application environments. The pump can also be integrated with control cabinets, pressure monitoring devices, valves, and other system components; a well-designed system ensures stable connections between the fire water source, the piping network, and terminal fire-fighting equipment. When the system demands water, the pump delivers the required flow and pressure—supplying water to facilities such as fire hydrants and sprinkler systems—to meet the fire protection system’s operational needs. For fixed fire-fighting systems requiring continuous operation, the proper matching of the pump casing, impeller, shaft assembly, and motor is crucial to ensuring equipment performance; therefore, appropriate specifications should be selected for specific projects based on rated flow, rated head, piping network pressure, and power supply conditions. Featuring a vertical structure, single-stage centrifugal operation, diverse specification options, and a compact installation footprint, these fire pumps deliver reliable water delivery capabilities across various fire-protection projects and—through optimal selection and system integration—meet the fire-water supply requirements of diverse building and industrial facilities.
