  • Features

1. The single-blade or double-blade impeller structure adopted greatly improves the dirt passing capacity, and can effectively pass fiber materials 5 times the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. The mechanical seal adopts a new hard and corrosion-resistant tungsten carbide material, and the seal is improved to a double-end seal, so that it can operate in the oil chamber for a long time, and the pump can run continuously for more than 8,000 hours.
3. The pump is a vertical structure. When working, the pump body is immersed in the liquid, so it is easy to start, there is no problem of exhaust and evacuation, and it has the characteristics of no leakage, etc. The underwater depth can reach 0.5 to 7 meters.
4. The overall structural design is reasonable, the noise is low, the energy saving is energy-saving, and the maintenance is convenient.
5. The shaft connection structure is advanced and reliable. The pump and the motor are connected by a winding coupling. The pump shaft size is precise, which ensures the smooth operation of the pump and leaves enough safety factor.
6. It can be used within the full head range to ensure that the motor will not be overloaded.
7. It can be equipped with a liquid level automatic control cabinet according to user needs. According to the required liquid level changes, it can automatically control the start and stop of the pump, without the need for special personnel to supervise it, and it is extremely convenient to use.
