Abstract

Il trovato è riferito ad una pompa centrifuga del tipo comprendente un corpo di supporto per un motore sincrono a magneti permanenti, al cui rotore è accoppiata una girante, e per una voluta in cui è alloggiata la stessa girante.Il corpo e la voluta definiscono un involucro stagno che contiene in rispettive camere rotore e girante separandoli dalla parte statorica del motore.La pompa ai caratterizza per il fatto che il rotore è solidale ad un albero rotante su cuscinetti radenti sostenuti da supporti elastici bloccati nella corrispondente camera e dei quali uno definisce un anello di tenuta idraulica fra le due camere del detto involucro.The invention relates to a centrifugal pump of the type comprising a support body for a synchronous motor with permanent magnets, to whose rotor an impeller is coupled, and for a volute in which the same impeller is housed. The body and the volute define a watertight casing which contains in its respective chambers rotor and impeller separating them from the stator part of the motor. The pump is characterized by the fact that the rotor is integral with a rotating shaft on sliding bearings supported by elastic supports blocked in the corresponding chamber and of which one defines a hydraulic seal ring between the two chambers of said casing.
