Abstract
A vertically disposed centrifugal pressure filter for suspensions has a closed casing containing a sectional hollow rotary shaft, the long section of which is equipped with filter disks within the casing. A relatively short shaft section has a plug-in connection with the lower end of the long shaft section and has bearing in an outside bearing casing detachably connected to the filter casing. Dynamic sealing means is provided between the short shaft section and the bearing casing, so that when the bearing casing and short shaft section are disconnected from the filter casing and long shaft section, the seal for the short shaft section is not disturbed. The filtrate passes through the shaft sections and to the outside through the bearing casing.
