1. The overall structure of the motor and China rubber impeller is statically sealed, and the electric China rubber impeller is completely leak-free;

2. Fully enclosed, non-leakage structure can transport toxic and harmful liquid substances;

3. The shielded water-cooled motor is used to save the cooling fan, so that the china rubber impeller runs quietly and quietly, and is suitable for occasions with high environmental noise requirements;

4. The graphite sliding bearing lubricated by the transmission medium reduces the running noise and does not require manual oiling, which reduces the maintenance cost. In recent years, silicon carbide SIC, superhard, etc. have been added to the bearing material, and the service life is better than that of graphite bearings;

5. The vertical structure can be installed on the pipeline like a valve, which is convenient and quick to install. It is only necessary to pull out the motor and impeller during maintenance without removing the pipeline.

6. It can be installed and operated together with shock absorbers or pads to reduce the noise of the electric china rubber impeller during operation.
