45kW Submersible Axial Flow Pump with 1300 m³/h Flow and 8m Head for High-Flow Drainage

The 400QSH1300-8-45kW submersible axial flow pump is engineered for high-flow, low-head water transfer and drainage applications. With a rated flow of 1,300 m³/h, rated head of 8 m, and motor power of 45 kW, this pump is ideal for municipal flood control, stormwater drainage, agricultural irrigation, river water transfer, aquaculture, and industrial circulating water systems.

The integrated pump and submersible motor operate directly underwater, eliminating the need for long transmission shafts and complex above-ground structures. This compact design makes it suitable for both permanent pumping stations and emergency drainage projects.

Voltage, frequency, cable length, pump material, control method, and installation dimensions can be configured according to project requirements. Final parameters should be confirmed through technical selection and manufacturer's approved data sheet.

The motor drives an axial-flow impeller that moves water parallel to the pump shaft. This hydraulic design enables large-volume water transfer at relatively low heads. The submersible operation allows installation inside discharge tubes or pump wells, simplifying station layout and reducing above-ground space requirements.

• Municipal flood control and stormwater drainage
• Drainage of low-lying areas and underground facilities
• Agricultural irrigation and farmland drainage
• River, lake, and reservoir water transfer
• Municipal rainwater pumping stations
• Aquaculture pond water circulation
• Industrial circulating water systems
• Port and construction site drainage
• Emergency flood drainage projects
• Water diversion and regional water distribution

This pump is designed for clean water, rainwater, river water, and liquids with similar physical properties to water. Temperature, sediment concentration, solid particle size, and chemical composition must be confirmed before selection.

To ensure proper pump selection, please provide the following details:

• Required flow rate
• Total dynamic head (including static water-level difference and friction losses)
• Minimum, normal, and maximum water levels
• Liquid temperature and composition
• Sediment concentration and particle size
• Power supply voltage, frequency, and phase
• Pump well or discharge tube dimensions
• Required cable length
• Daily operating hours and start frequency
• Control panel and automation requirements

Before installation: Verify pump well dimensions, mounting interface, lifting equipment, cable insulation, and electrical protection devices. Always use specified lifting points—never use power cables as lifting ropes.

Before operation: Confirm power supply, impeller rotation direction, water levels, and control panel settings. Monitor current, voltage, flow, vibration, noise, and water-level changes during operation.
