Abstract (en)
[origin: EP1039140A2] The pump has a driven rotor (1) with a ring of blade chambers on one side, and rotor blades to define the chambers. The rotor blades (3) are positioned along the height of the rotor chambers (2) at an angle, which is defined by a formula calculated from the distance between the center of the rotor and a point on a rotor blade, the distance between the rotor center and a chosen point on the rotor blade, and a set angle. The set angle on the radial outer edge of a rotor blade is between 30 and 40 degrees .
