Two powerful catch magnets are mounted on the outside of the stainless steel (304) casing which, depending on the model, separate coarse or very fine iron particles from various different materials flows. The external pole magnet can be mounted in free-fall lines or pneumatic transport lines and is suitable for the bulk, plastics, recycling and animal feed industries and for the pharmaceutical and foodstuffs industries. An advantage of this external core mounting is that there is no bridging on the inside or clogging up of the material. Cleaning is done without interrupting the product flow. As the valve-box is fully integrated into the design, the construction height remains limited.

Rare earth magnets

Neodymium-Iron-Borium (Neoflux = rare earth) magnets are used for the self-cleaning external pole as these remove very fine iron particles. The casing is completely smooth, welding seams are finished off so that there is no breeding-ground for bacteria. Magnets such as this are used in filler lines or for the loading of silos. Pneumatic controls take care of the cleaning of the magnet. This is started by a 24V DC signal and then runs completely automatically. The external pole magnet can be supplied in various different models up to an inlet/outlet of 300x1000 mm.
