1. Mechanical seals are installed in the submersible motor, the material of the seal in tungsten carbide. A special finger sleeve structure in used at the cable out-coming place for good sealing and corrosion prevention;


2. The impeller is designed with special anti-twisting curve of reasonable structure.


3. Of the motor's windings, the dielectric grade is F and the protective grade is IF 68.


4. Compact structure, easy installation and overhaul simple operation and long duration.



Working Principle


The propeller blade of a special structure starts slow moving driven by the under-water motor to produce a powerful water flow flowing in a lower tangential direction to make the liquid’s power increased and produce strong stirring to reduce the precipitation under the water, thus realizing liquid stirring and flowing.
