Abstract
In a hydrocyclone plant for treating fibre suspensions comprising a multiplicity of hydrocyclone bodies (1) each hydrocyclone body is mounted in a hole in a wall (5) and is sealed to the wall with the aid of a sealing ring (18). According to the invention the sealing ring is made of an inexpensive chemical resistant material and is radially cut through, so that two free ends are formed on the sealing ring. The hydrocyclone body is provided with a sealing surface (12) having a radial extension which increases along the hydrocyclone body. Axially along the sealing surface (12) a projection (22) extends between the free ends of the sealing ring. When mounting the hydrocyclone body the sealing ring (8) is adapted to be entrained by the wall (5) along the sealing surface (12), so that the sealing ring is expanded and seals between the sealing surface and the wall.
