Two-stage pump consists of a set of channels (4) of the first step and the a set channel (5) of the second step are arranged alternately on the impeller (1). The channels (4) have a first step of axial suction inlets (6) of the axis of rotation of the impeller (1) and the channels (5) have a second degree of radial discharge outlets (7) to the coil (2) for discharging the liquid. The impeller (1) is arranged transducer (3), to the inlet mouth of the axial output (8) of channels (4) of the first step of the circumference of the impeller (1). The output from a converter (3) opens into axial zones (9) channels (5) the second level of the axis of rotation of the impeller (1). |
