advantage

1. The lower pump is directly installed on the storage of the transport medium, without an additional area.

2. The traditional liquid pump uses a unique centrifugal dual -balanced impeller for transporting clean medium such as solid particles. It has low vibration noise and high efficiency; Short fiber liquid runs smoothly and not blocked.

shortcoming

1. The intermediate slot needs to be increased, and the middle slot level needs to be controlled during operation;

2. The maintenance is more complicated and must be replaced regularly;

3. High maintenance rate and high cost;

4. Need to be sealed;

5. Traditional liquid pumps are not suitable for transportation of flammable and explosive materials.

6. The new type of liquid pump is not suitable for transporting materials with strong granules with particles.
