Abstract

A sheet metal casing with differentiated thickness for centrifugal pumps includes a substantially cup-shaped main body (2) formed by a peripheral wall (3) which is continously joined to a transverse end wall (4); the body is coupled to a transverse sealing plate (9) opposite to the end wall (4) so as to define a pressure chamber (13) enclosing an impeller (14); a tangential delivery port (7) and an axial suction port (6). A funnel-shaped reinforcement element (20), has a frusto-conically shape and a transverse end portion (21) arranged inside the main body (2) and a substantially cylindrical longitudinal end portion (22) extending from the body main coaxially to the suction inlet (6). The transverse end portion (21) of the reinforcement element is at least peripherally overlapped and rigidly sealingly coupled to the end wall (4) of the main body so as to thereby define the transverse wall of the casing which is adjacent to the suction port in contact with the pumped liquid. <IMAGE>
