Abstract

Una cassa per pompa centrifuga in lamiera metallica, comprende un mantello integrale (1) atto ad accogliere una girante (8), il quale presenta una porzione laterale sporgente (1a) provvista di un'apertura di mandata (15), una parete di estremità (7) bombata assialmente verso l'esterno provvista di un'apertura di aspirazione (3), ed una flangia di collegamento per l'accoppiamento con un motore, in cui una bocca di aspirazione (4) è fissata alla parete di estremità (7) in comunicazione con l'apertura di aspirazione (3), una flangia di aspirazione (14) è connessa alla bocca di aspirazione (4), ed almeno un elemento di rinforzo (1) è previsto tra la flangia di aspirazione e la parete di estremità (7) per il loro reciproco collegamento. All'interno del mantello (1) è previsto un involucro o flangia unitaria interna (42) che presenta una porzione periferica esterna rigidamente fissata alla faccia interna di detta parete di estremità (7) in una posizione di quest'ultima radialmente esternamente spaziata rispetto ad almeno un elemento di rinforzo (19), ed una porzione cilindrica interna (42b) che serve da anello di rasamento atto a cooperare con la girante (8).A centrifugal pump casing in sheet metal, includes an integral casing (1) adapted to accommodate an impeller (8), which has a protruding side portion (1a) provided with a delivery opening (15), an end wall (7) axially rounded towards the outside provided with a suction opening (3), and a connection flange for coupling with a motor, in which a suction mouth (4) is fixed to the end wall (7 ) in communication with the suction opening (3), a suction flange (14) is connected to the suction mouth (4), and at least one reinforcing element (1) is provided between the suction flange and the ends (7) for their mutual connection. Inside the casing (1) there is an internal unit casing or flange (42) which has an external peripheral portion rigidly fixed to the internal face of said end wall (7) in a position of the latter radially externally spaced with respect to at least one reinforcing element (19), and an internal cylindrical portion (42b) which serves as a leveling ring adapted to cooperate with the impeller (8).
