A self-emptying separator includes a rotatable drum with an inlet, a liquid outlet, outlet openings for solid material, and a control system. A flowable starting product is cleared of the solids in continuous operation in a centrifugal field in the rotating drum. A continuous discharge of a clear phase is performed. A solid phase is discharged via the outlet openings from a solids collecting space of the drum into an annular solids catcher. The solids catcher has a device for generating a fluid curtain against which the solids, issuing from the outlet openings for solid material, impact.

An outlet nozzle for centrifugal drums has a nozzle body with at least one cylindrical portion and having an insert connected to the nozzle body. An inlet channel and an outlet channel, which is oriented at an angle with respect to the inlet channel, are formed in the nozzle body. The insert has a torque transmitting contour for arranging a tool with a complementary tool torque transmitting contour in position in order to rotatingly secure the nozzle body in an opening of a rotatable centrifugal drum and to release said nozzle body. The insert also has a polygonal cross-section, which is smaller than the cross-section of the cylindrical section. The insert starting from the polygonal, in particular, rectangular cross-section, merges with the cylindrical section of the nozzle body over rounded surfaces having a radius greater than 1.0 mm.

A centrifugal separator includes a separator bowl delimiting therein a separation space and being configured to rotate about a rotational axis and nozzle members arranged peripherally at the separator bowl. Each nozzle member forms a nozzle outlet providing a passage from the separation space to a space outside the separator bowl. The centrifugal separator includes a protective member arranged downstream of each nozzle outlet at an outer periphery of the separator bowl. The nozzle member secures the protective member in relation to the separator bowl, at least in one circumferential direction of the separator bowl.
