1. WQZ(H) series external reflux sewage sludge submersible electric pump is mainly used for the transportation of external reflux sewage (sludge) in sewage treatment projects.

2. Lifting, discharge and transportation of low-head sewage and rainwater pumping stations

3. Discharge of sewage from hotels, buildings, schools and hospitals

4. Sewage discharge from municipal engineering and construction site

5. Wastewater discharge from rural biogas digesters, septic tanks, animal husbandry 

1. The Taifeng brand external reflux sewage sludge submersible electric pump is a low-head sewage sludge submersible electric pump developed and produced by introducing design and manufacturing technology of international advanced submersible electric pump. The electric pump operates throughout the full head without overload and is highly efficient and energy-saving when used within the specified head range.

2. The impeller structure adopts different blade structure forms, which have good dirt passing capacity, without entanglement or blockage phenomenon, is particularly suitable for the transportation of external reflux sludge in sewage treatment process, and operates stably under complex sludge conditions.

3. The motor's protection class is IP68, the rated voltage is 380V and 660V, the rated frequency is 50Hz or 60Hz, with variable frequency operation duty system of S1, and the insulation grade is F, or H for special requirements.

4. The electric pump is equipped with humidity and temperature sensor to enhance product reliability.

5. Electric pumps only require the collection pool and no ground pump room, which can save civil construction investment and reduce the project construction cost by 30-40%; It adopts self-coupling installation or wellbore installation and other forms, featuring simple and quick installation and disassembly.
