QHB Submersible Reflux Pump
Product Description
Introducing the QHB Series Submersible Reflux Pump, a marvel of engineering inspired by the advanced production techniques of submersible agitators. This innovative pump is crafted to excel in the reclamation of mixed liquids, denitrification, and nitrogen removal processes within Class II sewage treatment plants. Additionally, it is ideal for environments requiring a short delivery lift and a robust discharge capacity in ground drainage projects, ensuring peak performance and reliability.
Condition of Application:
1. To ensure optimal performance, the medium temperature should not exceed 40ºC during continuous operation.
2. The medium's pH value should be maintained between 5 and 9 to ensure the integrity and longevity of the pump.
3. The maximum submersion depth should not exceed 10 meters, providing flexibility for various operational needs.
