High-Head Vertical Turbine Fire Pump for Deep Water Source Applications
The high-lift vertical turbine fire pump adopts a vertical long shaft, underwater impeller and ground drive structure. It is suitable for deep water sources such as deep wells, pools, rivers and lakes. It can be configured according to flow rate, head and installation depth to meet the deep water intake and high-lift water supply needs of large fire protection systems.
High-lift vertical turbine fire pumps are fire-fighting water supply equipment suitable for deep wells, pools, rivers, lakes, and other deep water sources. They feature a vertical structure design, with the pump body and impeller assembly positioned at the deeper part of the water source, while the drive unit is installed on the ground. Power is transmitted to the underwater impeller via a long vertical shaft, causing the water to flow upwards along the guide structure, thus meeting the needs of fire-fighting systems for deep water intake and high-lift water delivery. Compared to conventional horizontal fire pumps, the main feature of vertical turbine fire pumps is the separate arrangement of the underwater pump body and the ground drive unit. The pump set’s column pipe and installation structure can be adjusted according to the actual water source depth, making them well-suited for special water intake conditions such as deep wells, deep pools, and large water storage facilities. According to official website information, the product range of this type of vertical turbine fire pump covers flow rates of approximately 5–1800 m³/h and heads of 20–234 m, with speeds ranging from approximately 980–3550 r/min. Specific parameters can be selected and matched according to the design requirements of the fire-fighting system. During operation, the underwater impeller converts the mechanical energy input from the drive unit into the pressure energy of the water flow through rotation. The water flows through the impeller and guide structure into the vertical column pipe and is then transported upwards. For fire-fighting water supply applications requiring higher head, a multi-stage impeller series structure can be used, allowing the water flow to gradually acquire energy in multiple stages, thereby increasing pressure output capacity. This is suitable for high-rise buildings, large industrial facilities, storage facilities, and other projects with high fire-fighting water supply head requirements. The vertical long-shaft structure is also a key performance feature of this equipment. The drive shaft extends downwards from the ground and connects to the underwater pump body, continuously transmitting power during deep-water water intake. According to the official website, the long shaft can be supported using structures such as rubber bearings, and appropriate lubrication and cooling methods can be adopted based on the equipment structure to meet the operational requirements of the long-shaft system. The ground-based drive method places the main power components, such as the motor and transmission device, above the water surface, making daily inspection and maintenance relatively convenient. Different drive forms can be selected according to project conditions, including vertical hollow shaft motor drive, and configurations using belt or gearbox transmission. Some projects can also use diesel power based on actual needs. Regarding material configuration, the official website lists material options such as alloy cast iron or silicon brass impellers, alloy cast iron pump casings, stainless steel tapered sleeves, carbon steel or stainless steel pump shafts, rubber bearings, and seamless steel pipe columns. These can be rationally configured according to the conveying medium and specific engineering conditions. Since the pump body and impeller need to be installed inside the water source, the actual selection requires comprehensive consideration of factors such as water source depth, static water level, minimum water level, required flow rate, design head, well or pool size, and drive method to ensure that the pump set’s installation dimensions and hydraulic performance match the site conditions. For deep well water intake projects, the pump set flow rate also needs to be rationally determined based on the actual water output capacity of the water source to avoid mismatch between equipment selection and water source conditions. The vertical turbine fire pump’s inlet is located near a deeper water level, reducing the installation limitations faced by ordinary surface pump sets when drawing water from deep sources. Simultaneously, continuous water intake and pressure delivery are achieved through long shaft drive and underwater impeller structure. For fire pools, deep wells, rivers, lakes, and other large water sources, appropriate pump bodies, column pipe lengths, and drive configurations can be designed according to the water source type and fire protection system requirements. With a complete set design, the equipment can integrate the ground drive unit, vertical column pipe, underwater pump body, and related connecting components into a complete fire water supply unit, facilitating engineering design, installation, and operation management. Overall, high-lift vertical turbine fire pumps, through their vertical long shaft drive, underwater impeller water intake, and multi-stage pressurization, can provide corresponding equipment solutions for deep water sources and high-lift fire water supply conditions. They feature strong adaptability to water intake depth, easy ground maintenance of the drive unit, a wide range of flow and head configurations, and the ability to select different drive methods according to project conditions. They are suitable for industrial and large-scale fire water supply projects that require fire-fighting water from deep wells, large pools, rivers, or lakes.
