Submersible axial-flow pump for high-flow irrigation

Core Technologies and Structural Advantages

Integrated Coaxial Pump-Motor Design

The pump and motor adopt a direct-coupled coaxial structure, significantly improving rotor concentricity. This design reduces shaft wear during operation, ensuring smooth running, low vibration, and low noise while extending service life.

Large Flow and Non-Clogging Hydraulic Design

The impeller utilizes an advanced hydraulic model with a wide flow passage and excellent flow performance. It delivers high-capacity water transfer while providing outstanding non-clogging capability, allowing it to handle lightly contaminated water and liquids containing impurities with stable and reliable operation.

High-Reliability Sealing System

The pump is equipped with double or triple mechanical seals to effectively prevent water leakage. The motor features an IPX8 protection rating and F-Class or H-Class insulation, ensuring safe and reliable long-term underwater operation.

Intelligent Protection and Monitoring

Built-in protection devices include winding overheat protection, bearing temperature monitoring, and oil chamber leakage detection. The system can be connected to a smart cloud platform for remote monitoring, intelligent alarms, and automated operation and maintenance management.

Premium Bearing Configuration

To withstand high axial loads, the pump is equipped with dedicated thrust bearings and high-quality rolling bearings. The optimized structure and lubrication system ensure long service life and reliable performance.

Installation Methods and Applications

Flexible Installation Options

The pump supports horizontal, vertical, and inclined installation configurations. Customized layouts can be designed according to site conditions, water level differences, and space limitations. Complex civil construction is not required, making installation quick and convenient.

Flood Control and Drainage Systems

Suitable for rapid drainage of stormwater from underpasses, underground passages, subway tunnels, and low-lying residential areas, helping ensure urban safety and uninterrupted transportation.

Wastewater Treatment and Pumping Stations

Widely used as terminal lifting pumps in municipal stormwater networks, inlet pumps and return sludge pumps in wastewater treatment plants, and emergency water transfer equipment for river water quality improvement projects.

Industrial Water Applications

Provides flood drainage, process water supply, and cooling water circulation for industrial and mining facilities, meeting the requirements of various industrial environments.

Customer Benefits and Economic Value

Reduced Civil Construction Costs

Since the unit operates underwater, pump station structures can be greatly simplified. Installation space requirements are reduced, and total civil construction costs can typically be lowered by 30%–40%.

Energy Saving and High Efficiency

The pump offers excellent overall efficiency. Compared with traditional long-shaft axial flow pumps, energy consumption can be reduced by approximately 20%, resulting in lower long-term operating costs.

Improved Working Environment

With fully submerged operation, the pump station experiences no excessive heat or noise pollution. The system supports remote operation and automatic control for enhanced convenience.

Easy Maintenance

The unit can be easily lifted and removed for maintenance. Eliminating the long shaft transmission components found in conventional systems improves operational reliability while reducing maintenance complexity and costs.
