Abstract (en)
Centrifugal pump driven by a synchronous motor and comprising a pressure chamber (3) having a circular cross-section and provided with a peripheral outlet (4) from which a delivery pipe (5) branches off radially. In said pressure chamber (3) is provided a baffle (11) which is freely hinged on an axis parallel to the drive shaft (7) of an impeller (8) formed with radial blades (9). Depending on the direction of rotation of the impeller (8), the baffle (11) is moved to either of two operative positions in which a free end portion (13) thereof abuts against the edge of the outlet (4). <IMAGE>
