    摘要： A separating device for removing solid particles from fluids, a process for making said separating device and the use of said separating device for removing solid particles from fluids in e.g. a process for extracting fluid from hydrocarbon extraction wells or water. The separating device comprising a concentric stack of at least three annular discs (7) defining a central annular region along a central axis, each annular disc having a first major surface (8) with at least one spacer (9), whereby the discs, when stacked, define a first planar contact area (10) and a first separating gap (14). The discs are joined together by diffusion welding. Each annular disc comprises a material selected from the group consisting of (i) ceramic materials; (ii) mixed materials having fractions of ceramic or metallic hard materials and a metallic binding phase; and (iii) powder metallurgical materials with hard material phases formed in-situ.
