POMPE CENTRIFUGE VERTICALE A ROUES MONTEES EN OPPOSITION

摘要

The pump has a superimposed hydraulic cell (C1) including a movable wheel (2) provided with an axial inlet (20) and a radial outlet (21) for fluid to be pumped. A delivery unit i.e. volute (11), of the cell (C1) delivers the fluid to an inlet of the wheel (2) of another hydraulic cell (C2). The cell (C1) has an additional coaxial wheel (2') mounted in opposition above the wheel (2) such that the fluid passes through the wheel (2) along an upward direction and is fed into the wheel (2') that crosses along a downward direction before directed to the wheel (2) of the cell (C2).
