The centrifugal pump is a hydraulic turbomachine capable of processing fluid through centrifugal effect in fixed and rotating channels that are always open, without altering the fluid's compressibility. Hence the name centrifugal pump. The mechanical movement imparted by the motor to the impeller provides kinetic energy to the flow (acceleration in a radial direction) which is then transformed into pressure energy in the subsequent diverging channels.
The main components of a horizontal centrifugal pump with mechanical seal are:
