A centrifugal pump is a powered device intended to move a fluid by means of the transmission of rotational energy from one or more driven rotors, called impellers. Fluid enters the quickly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller's vane tips. There are three other different options in this apparatus: 1. Variable speed of the pump. 2. Transparent head of the pump. 3. Pump with both variable speed and transparent head.
