The self-priming sewage pump mechanical seal adopts a new type of hard and corrosion-resistant tungsten carbide material, and at the same time, the seal is improved into a double-end seal, so that it can be operated in the oil chamber for a long time, and the pump can be safely operated continuously for more than 8000 hours. The self-priming non-blocking sewage pump has a compact structure, small volume, low noise, remarkable energy saving effect, convenient maintenance, no need to build a pump room, and the self-priming sewage pump can work in water, greatly reducing the construction cost. The self-priming sewage pump seal oil chamber is provided with a high-precision anti-interference water leakage detecting sensor, and a thermal element is embedded in the stator winding to absolutely protect the water pump motor.
