Technical Principles Of Chemical Centrifugal Pumps

The operating principle of a chemical centrifugal pump is based on centrifugal force. When the motor drives the impeller to rotate, liquid is drawn into the center of the impeller; under the action of centrifugal force, it is propelled outward along the flow channels between the vanes and ultimately enters the discharge pipe via the volute-shaped passage of the pump casing. The impeller design (such as open, semi-open, or closed types) directly affects the pump's efficiency and resistance to clogging. Additionally, chemical pumps typically employ double-end mechanical seals or magnetic drive seals to prevent the leakage of toxic or flammable liquids.
