ABSTRACT:
A novel seal arrangement is provided for use in processing apparatus of the type including a partition for separating zones of relatively high and low pressures. At least one aperture is provided in such partition, the aperture having a wall. A processing unit (such as a hydrocyclone) has a portion thereof located in such aperture so that an annular region is defined between such unit and the aperture wall. An annular seal of resiliently deformable material is located in this annular region and provides a seal between the above noted zones. This seal is of cup-shaped form and includes an annular outer seal lip which is radially spaced form the processing unit. This seal outer lip is connected to the remainder of the seal via an end wall. The seal outer lip has inner and outer surfaces and a free annular edge remote from the end wall. This inner surface is exposed, in use, to the zone of higher pressure such that the outer surface of the seal lip sealingly engages the wall of the aperture under the influence of the differential pressures acting on it. The seal is located relative to the wall of the aperture and the wall of the aperture is of such dimension that the sealing engagement between the wall and the outer surface of the seal lip occurs in an annular sealing region located generally between and spaced from both the seal end wall and the free annular edge of the seal lip.
