Product Description

QHB Submersible Reflux Pump

Product Description

The QHB series submersible reflux pump is an innovative solution crafted from advanced submersible agitator production techniques. Specifically designed for reclaiming mixed liquids, it plays a pivotal role in the denitrification and nitrogen removal processes at Class II sewage treatment plants. Its unique engineering is perfectly suited for environments requiring minimal lift and substantial discharge, making it indispensable in ground drainage projects.

Condition of Application:

1. For continuous operation, the medium's temperature must remain at or below 40ºC;
2. The pH level of the medium should be maintained between 5 and 9;
3. The maximum permissible submersion depth is 10 meters.
