Design Features & How It Works

QIAOLUODE wellbore axial flow irrigation pump operating in large open channel for flood control

How It Works

This irrigation pump uses a QZ/QH series submersible axial flow pump unit installed in a corrosion-resistant steel wellbore. Its unique closed water intake design prevents bottom sediment from entering the pump chamber. The integrated automatic desilting system continuously removes accumulated sediment.

Key Design Features

No forebay, no pump house, closed water intake
Integrated anti-silt, trash blocking and automatic cleaning
Ultra-low water level operation – works at 0.5m depth
Patented hydraulic lifting system for easy maintenance
20-year service life – corrosion-resistant steel

Frequently Asked Questions

According to our product specifications, the wellbore axial flow pump has a maximum flow rate of 7000 m³/h, making it the ideal choice for large-scale open channel applications.

No, this model is designed exclusively for open channel water delivery. For pipeline applications, we recommend our wellbore submersible irrigation pump.

Yes, it is specifically designed for low head, large flow flood control and drainage applications, capable of quickly removing large volumes of water after floods.

This pump can operate normally at a minimum water depth of 0.5m, thanks to its surface water intake design.

The pump is equipped with a hydraulic lifting system that can lift the entire pump unit above water for maintenance in just a few minutes, no need to drain the channel.
