Zusammenfassung:Centrifugal pump comprising a spiral pressure case 1 and a twin-inlet runner wheel 2, particularly suitable for conveying hot liquids, is provided with two internal covers 11, 12 separating the suction space 21 from the pressure space 22, which covers bear from the internal side against collars 13 of the spiral pressure case and which are by way of their packing surfaces pressed by the pressure within the spiral pressure case against packing surfaces of said collars. The collars are formed by a shearing ring 4 which is fastened in a circumferential groove 101 of an axial circular opening 10 of the spiral pressure case.
