The impeller is mounted in the pump shell and is fastened to the pump shaft. The pump shaft is driven directly by the motor. The pump shell has a liquid straw in the center. The liquid through the bottom valve and the suction pipe into the pump. The liquid outlet on the pump case is connected with the discharge pipe.

The pump is filled with the liquid being pumped before the pump starts; After start-up, the impeller is driven by the shaft, and the liquid between the blades must also rotate. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtained the energy to enter the shell of the volute pump at high speed from the outer edge of the impeller. In the volute, the liquid decelerates due to the gradual expansion of the flow path, and then turns some kinetic energy into static pressure energy, and finally, the higher pressure flows into the discharge pipe and sends it to the need place. 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. The pressure on the liquid surface of the tank is greater than the pressure of the entrance of the pump, and the liquid is continuously pressed into the impeller. Thus, as long as the impeller turns, the liquid will continuously be inhaled and expelled.

The working principle of the linear pump is different from that of any other pump, which is the principle of magnetic levitation and the structure of the spiral circulation physical structure to realize the transfer of the fluid, namely, cancel the shaft, cancel the shaft connection, and cancel the shaft seal structure. After starting, the current is transformed into a magnetic field, which drives the spiral ring, which means that the spiral ring improves the flow.
