Abstract

Pompa centrifuga avente un'aspirazione (5) ricavata centralmente su una parete frontale (13) di una voluta (12) che alloggia una girante (10) e che è formata da almeno due porzioni complementari (16, 17) accoppiate su un piano parallelo all'asse (15) della girante. La voluta (12) ha una lunghezza assiale costante e maggiore di quella della girante (10). Quest'ultima è provvista di un collare periferico (14 ) sporgente verso detta parete frontale (13) e adiacente ad essa, atto ad impedire il riflusso dell'acqua in pressione verso l'espirazione.Centrifugal pump having a suction (5) obtained centrally on a front wall (13) of a volute (12) which houses an impeller (10) and which is formed by at least two complementary portions (16, 17) coupled on a parallel plane to the axis (15) of the impeller. The volute (12) has a constant axial length greater than that of the impeller (10). The latter is provided with a peripheral collar (14) protruding towards said front wall (13) and adjacent thereto, apt to prevent the backflow of the water under pressure towards the exhalation.
