A separator device for removing magnetisable material from a fluid in which said material is suspended, comprises a first annular magnet (28), a second magnet (30) located within the boundary of said first magnet and a pair of metal plates (32), each of said magnets having faces of opposite magnetic polarity and each of said plates being disposed in abutment with a respective one of said faces of each magnet. Each of said plates has a plurality of passage means (40, 47, 50) for the passage of fluid from one side of the plate to the other and a plurality of projections (42, 44, 46, 48) defining magnetic pole pieces located adjacent to the passage means, the magnetic pole pieces on one of the plates being aligned with the magnetic pole pieces on the other of the plates and forming axially extending regions of magnetic attraction to which magnetic material passing through the adjacent passage means is attracted. |
