1. The whole machine is dry submersible pump, and the motor adopts oil chamber seal mode and is provided with mechanical seal inside, so that high pressure water and impurities are effectively prevented from entering inner cavity of the motor.

2. Besides the main impeller, there is the agitation impeller which can agitate the sludge deposited on the water bottom into turbulent flow and pump the sludge out.

3. The overflowing parts such as the impeller and the agitation impeller are made from high-hardness high chromium cast steel, have wear resistance, corrosion resistance and strong drainage capacity, and allow big solid particles to pass.

4. The motor is submerged in water, is not limited by suction stroke, and has high sludge suction rate and thorough desilting.

5. The integral device is simplified, needs no auxiliary stirrer device or ejector device, and has simple and convenient operation and low total investment of the unit.
Pumping tailing slurry for industrial and mining organizations, clearing silt in sedimentation basin, pumping silty sand or fine sand for seashore or port, pumping powdery iron ore for foreign countries, etc.
