Abstract
An invertible filter centrifuge is provided comprising a rotary drum which is mounted in a cantilever manner in a housing and has radial passages for filtrate, a lid which is axially displaceable relative to the drum and closes the free front side of the latter, a filler opening on the lid for suspension to be filtered, and filler pipe which, on the one hand, is secured to the housing and, on the other hand, penetrates the filler opening, the outlet end of the filler pipe being located inside the drum during the centrifuging operation, characterized in that for varying the pressure in the drum (16), the filler pipe (26) is connectable to a pressurization or depressurization source (44) and is sealed by a combined rotary and sliding seal (45, 46, 47, 53) on said lid (25).
