A slurry pump refers to a machine that increases the energy of a solid-liquid mixed medium through the action of centrifugal force (the rotation of the pump's impeller), and is a device that converts electrical energy into kinetic energy and potential energy of the medium. Mainly applicable to: mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum and other industries.

Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the volute pump casing, the liquid decelerates due to the gradual expansion of the flow channel, and converts part of the kinetic energy into static pressure energy. Finally, it flows into the discharge pipe at a higher pressure and is sent to the required location. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Since the pressure above the liquid level in the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller.
