Abstract

One embodiment relates to a pump device with an impeller; a pump housing, including a wall surrounding an interior having an inlet and an outlet. The impeller is provided in the interior of the pump housing. The pump housing includes at least one first part-region, at least two further part-regions and at least one third part-region. The at least one first part-region includes, to an extent of at least 60% by weight, based on the total weight of the first part-region, at least one nonmagnetic material, wherein the at least two further part-regions comprise, to an extent of at least 25% by weight, based on the total weight of the further part-region, at least one ferromagnetic material metal, wherein the at least one third part-region comprises a metal content in a range from 40% to 90% by weight, based on the total weight of the third part-region.
