An arrangement by mechanical planar sealings (4, 5), especially for centrifugal pumps and the like having a rotating shaft (3) comprising an axially outside the planar sealing arranged secondary sealing (7), an inlet (9) for flushing liquid and an outlet (14) for the flushing liquid and possibly through the planar sealing leaking pump medium, at least one drain passage (13) leading to the outlet and one liquid collection chamber (8) situated between the planar sealing and the secondary sealing. In order to secure that the flushing liquid is kept for a long time between the primary and secondary sealings and thus is utilized very efficiently, the liquid collection chamber is divided into two or more parts (8a, 8b) which are separated from each other by at least one dividing wall (12) which allows internal communication between the parts. <IMAGE>
