Bomba centrífuga con un alojamiento de bomba, un eje, rodete inserto al eje, un sello dinámico con cámara de sello, un repulsor montado al eje y un sello estático que comprende una cubierta de sello axialmente ajustable con un miembro de sello estacionario flexible y arreglado en conexión con una manga de eje arreglada al eje; miembro de sello. The present invention relates to a centrifugal pump, a shaft sleeve and a stationary seal member for a static seal used in connection with a dynamic sealing of a centrifugal pump. The invention relates to a static seal the clearance of which may be adjusted while the pump is running. Especially the invention discusses the novel structure of such a static seal. A characterizing feature of a centrifugal pump comprising a pump housing (8), a shaft (6), an impeller attached on the shaft, a dynamic sealing (4) having a sealing chamber (12) and a repeller (14) mounted on the shaft (6), and a static seal (2) arranged in a shaft space (42) behind the dynamic sealing (4) as seen from the direction of the impeller, said static seal (54, 54') comprising an axially adjustable seal cover (56) including a stationary seal member; and a rotary seal member arranged on the shaft (6), is that the seal cover (56) is provided with a flexible seal member (77, 92), whose counter member (68) is arranged in connection with a shaft sleeve (60) arranged on the shaft (6).
