Working principle of water pump
Apr 17,2026
The working principle of a water pump is mainly based on the power equipment (such as an electric motor) driving the impeller to rotate, thereby generating centrifugal force. When the impeller rotates, the liquid between the blades also rotates and is thrown out of the impeller and into the pump casing under the action of centrifugal force. As the liquid is continuously ejected, a low-pressure zone is formed at the center of the impeller, and the external liquid is sucked into the center of the impeller under the action of atmospheric pressure, thereby achieving continuous liquid transportation.
