Submersible Axial-Flow and Mixed-Flow Pumps

 The ZQB Series Submersible Axial-Flow Pump and HQB Series Submersible Mixed-Flow Pump represent next-generation replacements for traditional pump-motor units. These integrated motor-pump systems can operate submerged in water for extended periods, offering a range of notable advantages:

• Simplified Infrastructure: By submerging the pump, the need for complex civil engineering works and structural buildings is significantly reduced, saving 30–40% of total project costs.
• Ease of Installation: The integrated motor-pump design eliminates on-site shaft alignment assembly, enabling faster and more convenient installation.
• Low Noise & Improved Environment: Quiet operation and absence of heat buildup in the pump station improve working conditions. Full underground pump stations can be constructed to preserve surface landscapes.
• User-Friendly Operation: No pre-lubrication of rubber bearings is required. Remote control and automation capabilities are supported.
• Flood Protection: Effectively addresses motor flood prevention challenges in areas with significant water level fluctuations, such as riverside and lake regions.

demonstration of the type

The ZQB and HQB Series Submersible Pumps are widely used in agricultural irrigation and drainage, industrial/mining docks, urban construction, and power plant water supply and drainage systems.

• ZQB Series Submersible Axial-Flow Pump: Optimized for low-head, high-flow applications.
• HQB Series Submersible Mixed-Flow Pump: High-efficiency design with superior cavitation resistance, suitable for environments with large water level variations and higher head requirements.

service conditions

• Conveyed Medium: Water or other liquids with similar physical and chemical properties.
• Maximum Liquid Temperature: ≤40°C.
• Special Media: Optional customization available for high-temperature or mildly corrosive media.
