DFQN pond desilting sludge gas small mud pump Structural features

The DFQN submersible slurry pump is a coaxial integration of the water pump and the motor. When working, the motor shaft drives the water pump impeller to rotate,

 transferring energy to the slurry medium, causing it to generate a certain flow rate, driving the solid matter to flow, and realizing the transportation of the slurry.

Its main features are as follows:

1. The whole machine has a dry motor-under-pump structure. The motor is protected by a mechanical seal, which can effectively prevent high-pressure water and

 impurities from entering the motor cavity.

2. In addition to the main impeller, it is also equipped with a stirring impeller, which can stir the sludge settled at the bottom of the water into a turbulent flow and 

then extract it.

3. The impeller, stirring impeller and other main flow-passing parts are made of highly wear-resistant materials, which are wear-resistant, corrosion-resistant, 

non-clogging, have strong sewage discharge capabilities, and can effectively pass through larger solid particles.

4. It is not limited by the suction range, has high slag suction efficiency and more thorough desilting.

5. No auxiliary vacuum pump is required, making the investment cheaper.

6. No auxiliary stirring or spraying device is required, making the operation easier.

7. The motor is submerged underwater, eliminating the need to build complex ground protection and fixing devices, making management easier.

8. The stirring impeller is in direct contact with the deposition surface, and the concentration is controlled by the depth of penetration, so the concentration 

can be controlled more freely.

9. The equipment works directly underwater without noise or vibration, making the site cleaner.
