Abstract: This paper describes the operating principle and the constructive solution for a rotating volumetric pump with two profiled rotors. Calculation relations are established for the flow rate and the driving power of the rotating pump. An example of a calculation for determining the pump driving power according to the conveyed flow rate is presented; the flow rates were chosen for the case when the pump would be used in an irrigation pumping station. The pump can carry different categories of fluids such as: (1) Fluids with suspended particles (water + ash, water + sand), (2) Viscous fluids (oil, diesel, oil), (3) Multi-phase fluids (water + air, water + steam).
