1. The whole machine is of dry motor pump type structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity.
2. In addition to the main impeller, there is also a mixing impeller, which can stir the sludge deposited at the bottom into turbulence and then extract it.
3. Impellers, mixing impellers and other main flow passage parts are made of high wear-resistant materials, which are wear-resistant, corrosion resistant, non clogging, and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction distance, and the dredging is more thorough.
