Product Description

QHB Submersible Reflux Pump

Product Description

The QHB series submersible reflux pump is ingeniously engineered, drawing inspiration from the advanced production techniques of submersible agitators. This specialized equipment is meticulously crafted for exceptional performance in reclaiming mixed liquids, denitrification, and efficient nitrogen removal in Class II sewage treatment plants. It is also ideal for environments demanding a short delivery lift and substantial discharge capacity, making it indispensable for ground drainage projects, ensuring seamless and effective water management solutions.

Condition of Application:

1. The medium's temperature should consistently remain below 40ºC to ensure uninterrupted operation.
2. The medium's pH value must be within the optimal range of 5 to 9 for smooth functionality.
3. The submersion depth is limited to a maximum of 10 meters.

2. Comprehensive installation system for ease of setup.
3. Advanced electric control to enhance operational efficiency.
4. Essential connection attachments for seamless integration.

Notes: Users need to pre-embed the wall-threading pipe; however, the guide rod and lifting rod can be secured to the pond wall with expansion bolts, eliminating the need for pre-embedded components. Users must procure and fit pre-embedded parts and flap valves independently. Flexibility in installation is offered, with options for horizontal or vertical setup of the reflux pump.
