Abstract

Connection device and process for connecting a hydrocyclone to a distribution and collection device, in which distribution and collection device includes connection openings for addition or removal of liquid during operation of the hydrocyclone. Connection device includes a pipe piece having an insertion side structured and arranged to be insertable through one of the connection openings into distribution and collection device. The insertion side includes a circumferential groove and a radial protrusion positioned adjacent circumferential groove, and radial protrusion has an outer diameter smaller than an inner diameter of the one connection opening and is structured to remain within distribution and collection device. A ring-shaped seal, structured and arranged to extend from exterior of distribution and collection device to interior of distribution and collection device, has an outer diameter greater that inner diameter of the one connection opening, and ring-shaped seal is positionable in a tensioned state in circumferential groove.
