Product Description
QHB Submersible Reflux Pump
Introducing the innovative QHB series submersible reflux pump, meticulously crafted from pioneering submersible agitator technology. This cutting-edge equipment is tailored for reclaiming mixed liquids and is pivotal for denitrification and nitrogen removal in Class II sewage treatment plants. It excels in scenarios demanding short delivery lifts and substantial discharge capabilities, making it indispensable for ground drainage projects.
1. Ensure the medium's temperature remains below 40ºC during continuous operation for optimal performance.
2. Maintain the medium's pH value between 5 and 9 for efficient operation.
3. Ensure the maximum submersion depth does not exceed 10m to maintain pump integrity.

Scope of Supply:
1. State-of-the-art submersible reflux pump;
2. Comprehensive installation system;
3. Advanced electric control system;
4. Robust connection attachments.
Notes: While wall-threading pipes need pre-embedding, the guide and lifting rods are conveniently connected to the pond wall using expansion bolts, eliminating the need for pre-embedded parts. Pre-embedded components and flap valves should be acquired and installed by the user. Additionally, the reflux pump offers flexibility with either horizontal or vertical installation options.
