ABSTRACT:
This device relates to a pump for diphasic fluids and comprises an impeller having a hub which carries blades of a special design. The intersection of the outer surface of each blade with a cylindrical surface coaxial with the hub is a line whose angle of inclination, relative to a plane perpendicular to the hub axis, has a substantially constant value over about one third of the hub length. Furthermore, the intersection of the inner surface of each blade with said cylindrical surface forms a curve, or profile, which can be divided into four successive portions with different law of variations of the angle of inclination of this profile relative to a plane perpendicular to the hub axis.
