Abstract
The filter device is provided with a housing () and with a stack of filter plates () arranged therein at a spacing from one another. The housing includes an inlet () for the fluid to be filtered, an outlet () for the filtrate which is connected in a conducting manner to the inside of the filter plates (), and a cavity extending through the stack and formed by recesses in the filter plates (). The filter plate stack is arranged fixed to the housing, and a centrifugal pump () with several impellers () is arranged within the filter plate stack. This pump ensures an intensive through-flow of the filter plate stack and thus a removal of the filter residues.
