Slurry pump is a kind of centrifugal pump, which usually means that under the action of centrifugal force, the liquid is thrown from the center of impeller to the outer edge and obtains energy, leaving the outer edge of impeller at high speed and entering the volute pump shell. 

 In the volute pump case, the liquid slows down due to the gradual expansion of the flow channel, and then transforms part of the kinetic energy into static pressure energy, which flows into the discharge pipe at a higher pressure and is sent to the required place.

When the liquid flows from the middle center of the impeller to the outer edge, a certain vacuum is formed in the middle center of the impeller. Because the pressure above the liquid level of the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. 

Slurry pump is mainly used in mining, power plant, dredging, metallurgy, chemical industry, building materials and petroleum industry.
