Abstract

Pompa centrifuga a motore sincrono comprendente una camera di pressione (3) a sezione circolare che si raccorda con una bocca di uscita periferica (4) dalla quale si dirama radialmente un tubo di mandata (5). Nella camera (3) è previsto un deflettore (11) liberamente incernierato su un asse parallelo all'albero di trascinamento (7) di una girante (8) a palette radiali (9). Secondo il senso di rotazione della girante (8), il deflettore (11) si sposta fra due posizioni operative in cui una sua estremità libera (13) fa battuta contro il bordo della bocca di uscita (4).Centrifugal pump with synchronous motor comprising a pressure chamber (3) with circular section which is connected to a peripheral outlet (4) from which a delivery pipe (5) radially branches. In the chamber (3) there is a deflector (11) freely hinged on an axis parallel to the drive shaft (7) of an impeller (8) with radial vanes (9). According to the direction of rotation of the impeller (8), the deflector (11) moves between two operating positions in which one of its free ends (13) abuts against the edge of the outlet mouth (4).
