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.
