1. A ferromagnetic material removing device for removing ferromagnetic material from a fluid containing ferromagnetic material, wherein the device comprises:
at least one carrier encasing a plurality of permanent magnets arranged in an inner space of the carrier, wherein an outside of the carrier is configured to collect ferromagnetic material that is attracted by the permanent magnets, wherein the carrier is rotatably mounted;
a removing portion arranged and configured to remove the ferromagnetic material from the outside of the carrier; and
a driving assembly arranged to rotate the carrier, the driving assembly comprising one or more rotatably mounted engagement members brought into engagement with the outside of the carrier;
wherein the carrier is ring-shaped and the carrier comprises a magnet free zone.
