    摘要： The invention relates to a pump shaft (100), which comprises a first portion (102) that can be connected to an impeller (40) of a centrifugal pump, a second portion (104) configured to co-operate with a seal and suitable in particular for receiving an annular seal (22) of a mechanical seal, and a connecting portion (106), wherein the connecting portion (106) comprises a cylindrical cavity (118) having an end face (116) and in which a motor shaft (32) can be received, and the connecting portion (106) has at least two slots (112; 112'; 112") extending predominantly in an axial direction and at least two partially circumferential slots (110) extending predominantly in the circumferential direction, and the connecting portion (106) is sub-divided by the slots (110) extending in the circumferential direction into a guide portion (120) and, to create a force-locked connection with the motor shaft (32), into a clamping portion (124) elastically deformable in the circumferential direction and radial direction by a clamping means (140). In order to improve the pump shaft in such a way that a rotation free of imbalance can be reliably achieved, the connecting portion (106) according to the invention comprises a second guide portion (122) arranged on the side of the clamping portion (124) facing in an axial direction away from the guide portion (120), and at least two partially circumferential slots (114) extending predominantly in the circumferential direction are provided between the second guide portion (122) and the clamping portion (124).

    摘要： The invention relates to a rotating cleaner (1), comprising: a housing (2), which has a cavity (10) and an inlet (9) that can be connected to a fluid supply line; a shaft (5), which extends at least partially into the cavity (10); a spraying body (3), which is connected to the shaft (5) for conjoint rotation and comprises an outlet (8); and a plain bearing for rotatably supporting the shaft (5) in the housing (2), the plain bearing having a rotating bearing surface (23) a resting bearing surface (22), and a bearing gap. In order to improve the cleanability and the rotational characteristics of the rotating parts, the rotating bearing surface (23) and the resting bearing surface (22) according to the invention are each formed as a contiguous surface for supporting the shaft (5) in the radial and axial directions.

    摘要： The invention relates to a rotating cleaner (1) having a housing (2) which has a cavity (10) and an inlet (9) which is connectable to a fluid feed line, having a shank (11) which extends in sections into the cavity (10), having a spray body (3) which has an interior space (14), which spray body (3) is connected rotationally conjointly to the shank (11) and comprises an outlet opening (6), and having a bearing (16) for the rotatable support of the shank (11) in the housing (2). To improve the spray pattern, it is proposed that, in the interior space (14), there is arranged a fluid distributor (13; 13') which is designed for the uniform distribution of fluid.
