What is the working principle of the centrifugal pump?

Centrifugal pumps are widely used in chemical production.In this device, normal temperature liquids such as ethylene glycol and water are transported using centrifugal pumps. The centrifugal pump is driven by the motor. The pump body and the suction line are filled with liquid. The motor drives the impeller to rotate at a high speed. The impeller drives the liquid between the blades to rotate. Due to the centrifugal force, the liquid is swept from the center of the impeller to the outer edge of the impeller. The high pressure flows out along the discharge port. At the same time, a certain vacuum is formed at the center of the impeller due to the liquid being pumped out, and the pressure at the liquid level of the inlet storage tank (heat well, water tank, storage tank, etc.) is higher than that at the center of the impeller. High, therefore, the liquid in the sump enters the pump under pressure differential.The impeller rotates continuously, and the liquid is continuously sucked in and out.

Since the centrifugal pump is capable of transporting liquid,mainly by the action of centrifugal force, it is called centrifugal pump.
