Product Highlights

1. Innovative Dual-Flow Channel Design

The coaxial pump-motor integration ensures that water can be transferred forward and backward with equal efficiency.

Eliminates the need for bulky reversing mechanisms, reducing mechanical complexity and maintenance requirements.

Straight and symmetric flow paths reduce hydraulic losses by 30%-40%, ensuring smooth operation.

Capable of delivering 500–40,000 m³/h flow at low-head conditions (1–10m), meeting diverse bidirectional water transfer needs.

2. High-Efficiency, Energy-Saving Motor

Equipped with a copper-wound wet rotor motor, fully integrated with the pump.

Transmission efficiency exceeds 98%, while operational efficiency surpasses 85%, saving 20%-30% energy compared with conventional pumps.

Reduces long-term energy costs, providing a more sustainable and economical water management solution.

3. Durable and Corrosion-Resistant Construction

Pump body made from high-strength cast iron and stainless steel composites, treated for corrosion and rust resistance.

Dual mechanical seals and IP68 protection ensure stable underwater operation.

Resistant to sediment, mud, and a wide range of water qualities, including river water, rainwater, and coastal saline water, extending the pump’s service life.

4. Flexible Installation and Wide Applicability

Supports horizontal and inclined installation, adaptable to various site conditions without major civil works.

Widely applicable to hydraulic projects, urban flood control, river connectivity, coastal tide defense, industrial water circulation, and irrigation systems.

Customizable Bi-directional Axial Flow Pump channel dimensions and motor power ensure optimal performance for every site.

Specifications

Application Scenarios

1.Hydraulic Projects and Water Systems

Ideal for large-scale bidirectional water diversion and river connectivity projects.

Dual-flow design allows flexible water resource allocation and efficient water transfer, supporting ecological restoration and water optimization.

2.Urban Flood Control

Perfect for bidirectional discharge at flood control pumping stations.

Rapidly removes urban waterlogging or prevents backflow during extreme weather events, ensuring city safety.

3.Coastal Protection and Industrial Use

Effective in coastal tide-blocking and drainage systems, protecting inland areas from storm surges.

Suitable for industrial water circulation, large irrigation districts, and complex water quality environments.

Multi-installation options benefit retrofit projects with limited space.

Operation and Maintenance Guidelines

Installation:

Ensure pump and motor are coaxially aligned and the unit is level.

Inspect and clean dual-flow channels and sealing surfaces before operation.

Properly seal electrical connections to prevent water intrusion.

Operation:

Switch directions under no-load or low-load conditions.

Operate within the recommended 1–10m head and 500–40,000 m³/h flow.

Monitor motor current, voltage, temperature, and noise, especially during initial operation.

Maintenance:

Regularly clean the Quality Bi-directional Axial Flow Pump and flow channels, inspect impellers, bearings, and seals for wear or corrosion.

Maintain a detailed operation log, including mode switching and maintenance records.

For long-term shutdowns, drain the pump and protect metallic components from corrosion; check all systems before reactivation.
