The function of the impeller is to convert torque applied to the pump shaft to pressure and kinetic energy in the pumped liquid. It does this by the action of its vanes on the liquid and is the only component of a centrifugal pump that does so. The other components, even those that convert kinetic energy to pressure, absorb some energy from the liquid. Given its unique function, the impeller can be considered the fundamental component of a centrifugal pump.
