Abstract
An impeller (1) for centrifugal pumps has a first disk element (2), functionally arranged toward the inlet, which is coaxial to and faces a second disk element (3), which is functionally arranged toward the delivery and is connected rigidly to the first disk element (2) by virtue of a series of angularly spaced vanes (4) and is provided centrally with a means for fixing to a transmission shaft. The particularity of the present invention resides in that the impeller (1) includes a series of openings formed in the substantially peripheral region of the second disk element (3), between pairs of adjacent vanes, (4) substantially at the areas subjected to the greatest axial thrust.
