An integrated motorized pump (1) comprising an impeller (2) mounted on an axle (3), two magnetic drives (6) electromagnetically coupled to an electric motor (7), a casing (8) with a flowing space (9), an inlet channel (10) and an (11). The impeller (2) has circumferential arrayed magnetic means (13) magnetized in the direction parallel to the axle (3). The electric motor (7) comprising said impeller (2) as a rotor, and two stator plates (20). The stator plates (20) are covered with a liquid tight coating and comprise circumferential arrayed coils (21) etched on circuit board metal layers (22). Each magnetic drive (6) comprises a stator (14) with circumferential arrayed coil windings (16) and two magnetized disks (15). The magnetized disks (15) are mounted on the axle (3) perpendiculary to it and have a circumferential carry of radially extending poles (17).
