Product Description

QHB Submersible Reflux Pump

Product Description

The QHB Series Submersible Reflux Pump is meticulously engineered utilizing the production techniques of submersible agitators. This specialized equipment excels in the reclamation of mixed liquids, as well as in the critical processes of denitrification and nitrogen removal within Class II sewage treatment facilities. It is also ideal for environments demanding a short delivery lift and substantial discharge, making it a perfect choice for ground drainage projects.

Condition of Application:

1. Continuous operation requires the medium's temperature to remain below 40ºC;
2. The pH range of the medium should be maintained between 5 and 9;
3. Ensure the maximum submersion depth does not exceed 10 meters.
