Abstract

A pump device of centrifugal type comprising a pump housing (1) with an axial inlet opening (10) and a tangential outlet opening (11) and also an impeller (2) arranged rotatable about an axis of rotation (27), the impeller comprising blades (33, 45) for transporting a fluid from the inlet opening to the outlet opening, and also a drive means (3) connected to the impeller for driving the impeller. In accordance with the invention the impeller comprises a plurality of adjacent pairs of blades (51) defining between them channels (14) with adjustable flow openings (52) for the fluid, each comprising a main blade (33) arranged on a main blade wheel (28) rotatable about the axis of rotation, and also a regulating blade (45) arranged on a regulating-blade wheel (29) and rotatable together with the main blade wheel and pivotable in relation to the main blade wheel, the pump device comprising a control device (13) connected to the regulating-blade wheel which, by turning of the regulating-blade wheel in relation to the main blade wheel, is arranged to regulate the flow openings.
