Abstract
The invention concerns a rotor machine and an impeller, of which the rotor machine is intended to function as a liquid pump or as an agitator in a fluid such as a liquid or a colloid, whereby the rotor machine has a pump casing () with an impeller () mounted in bearings in a manner that allows rotation around an axis (X), and in which the rotor machine has three principal flow pathways, comprising: —an axial inlet opening () with a defined area of opening (Ain) —a radially oriented outlet opening () with a defined area of opening (Aut), and —a series of radially extending blades () that, distributed around the circumference of the impeller, form between them a number of flow channels (-). In order to achieve an improved working capacity, the area of opening (Ain) of the inlet opening (), the area of opening (Aut) of the outlet opening and the total effective area of opening of the flow channels (-) that extends through the impeller are so mutually designed that the three principal passages of the rotor machine are filled and emptied of the said fluid in an essentially equal manner.
