Centrifugal is inertia performance. Such as water droplets on the umbrella, umbrella slowly rotating, water droplets turn will follow the umbrella, it is because the umbrella with droplets of friction as to the result of the centripetal force of the water droplets. But if the umbrella rotational speed, the friction force is not enough to make water droplets to do circular motion, then the water will be separated from the umbrella to the outer edge movement. As with a rope to pull the stones do circular motion, if too fast, the rope will disconnect, stones will fly out. This is what is called a centrifuge.

The centrifugal pump is designed according to this principle. The high speed rotating impeller blades drive the water to rotate, and the water is ejected to achieve the purpose of conveying.

There are many kinds of centrifugal pumps. It can be divided into civil and industrial pumps, which can be divided into clean water pump, impurity pump, corrosion pump and so on.
