Establishing the Volumetric Efficienty of the New Type of Volumetric Pump

The paper establishes an original computation formula for the flow rate of the fluid transported by a new type of rotating machine with profiled rotors, the theoretical characteristic diagram of the machine - flow rate versus machine speed - is built. The scheme of the test stand used for performing measurements needed in order to build the experimental diagram is presented. The variation of the volumetric efficiency of the working machine in function of the machine speed is finally described.
