Abstract
In the first part of the paper the power consumed to overcome the viscous friction between the rotors and the case in case of a rotating volumetric pump is calculated. An experimental stand used to test this new type of volumetric pump with rotors profiled is presented; the power at the working machine couple is determined and an energy balance of the installation is issued.
