Beschreibung
Zusammenfassung:	The centrifugal pump with opposed impellers comprises a pump body (10), which has an internal cavity having a longitudinal axis and defining a first chamber (11) and a second chamber (12) adjacent to each other, separated by a partition wall (13). The pump body (10) forms a suction inlet (14) in communication with said first chamber (11) and a delivery outlet (15) in communication with said second chamber (12). A first impeller (21) and a second impeller (22) are arranged, in opposite positions, respectively inside said first chamber (11) and said second chamber (12) of the internal cavity, said impellers (21, 22) being equipped with respective axial hubs (23, 24) adapted to be associated with a driving shaft (20) coaxial to said longitudinal axis. The centrifugal pump comprises a plurality of conduits (30) adapted to convey the liquid coming out of said first impeller (21) to the axial inlet of said second impeller (22).
