Aquaculture wastewater QJB7.5/12-620/3-480 submersible mixer

Product FeaturesAquaculture wastewater QJB7.5/12-620/3-480 submersible mixer

1. The high-power underwater agitator has a compact structure, small volume, light weight, simple operation and maintenance, easy installation and maintenance, and long service life.

2. The impeller has a well-designed hydraulic structure, high working efficiency, and the swept back blades have self-cleaning function to prevent debris entanglement and blockage.

3. Mixing with the aeration system can significantly reduce energy consumption, increase oxygen filling capacity, and effectively prevent sedimentation.

4. The insulation level of the motor winding is F level, and the protection level is IP68. Imported disposable lubrication maintenance free high-quality bearings are selected, which have oil chamber leakage detection, motor winding overheating protection, and anti condensation devices, making the operation of the motor safer and more reliable.

5. Two independent mechanical seals, the friction material of the mechanical seal is corrosion-resistant tungsten carbide.

6. The cable sealing design of * eliminates the hidden danger of cable leakage.

7. The standard components adopt point solution separation technology, which can effectively prevent corrosion.
