DETAILED DESCRIPTION The aim is achieved by a centrifugal pump for liquids, in particular for blood in extracorporeal circulation, according to the invention, comprises a body for the containment of an impeller, said impeller may have the shape of a disk with magnets inside it and is provided, on both faces, with blades adapted for making contact with the liquid; said containment body having at least one liquid inflow connection, connected to ducts for conveying said liquid proximate to the center of the impeller on both sides thereof, and having at least one liquid outflow connection.
The containment body may be shaped so that it can be removably inserted into a seat defined in a fixed base within which there is at least one magnet, faces said seat and being connected to means adapted for rotating it, so as to rotationally entrain said impeller.
Further characteristics and advantages will become apparent from the description of two preferred, but not exclusive, embodiments of the invention, illustrated only by way of non-limitative example in the accompanying drawings.
