A centrifugal impeller, particularly for fluid-operated pumps, comprising a first disk- shaped body and a second disk-shaped body, which are coaxial and mutually opposite so as to form an interspace within which multiple radial vanes are arranged; the impeller is centrally provided with means for coupling to a transmission shaft. The impeller has a first impeller portion and a second impeller portion, which are mutually engaged; the first impeller portion comprises the first disk-shaped body and a part of the vanes, while the second impeller portion comprises the second disk-shaped body and the remaining part of said vanes. The present invention also relates to a method for manufacturing a centrifugal impeller, particularly for fluid-operated pumps. |
