ABSTRACT:
A plate-type filter that is provided with a sealing element that is disposed in the flow path of liquid that is to be filtered and seals off the in-flow region relative to the filling space of the filter housing. The sealing element is movable into its sealing position under the pressure of in-flowing liquid. The sealing element is therefore in the sealing position only when liquid is flowing in. When the filter elements are rotated for centrifuging off the filter cake, the sealing element is no longer in its sealing position due to the absence of liquid pressure, so that the sealing element is not stressed during the centrifuging process.
