The invention relates to a rotary lobe pump for conveying a fluid medium containing solids, said rotary lobe pump comprising two rotary lobes each having rotary lobe vanes engaging with other and each having a rotational axis and an outer periphery, wherein the rotational axes of the two rotary lobes are spaced apart from each other and arranged parallel to each other and wherein the outer peripheries of the two rotary lobes partially intersect each other, and further comprising a housing with an inlet opening and an outlet opening and an inner wall and an outer wall, the inner wall of the housing enclosing a respective section of the outer peripheries of the rotary lobes and wherein the rotary lobe pump is adapted to convey the medium in a feeding direction from the inlet opening to the outlet opening. According to the invention, the rotary lobe pump is characterized in that the outlet opening on the inner wall of the housing has a maximum discharge enlargement that is greater in a direction running parallel to the plane of the rotational axes and perpendicularly to the rotational axes than the distance between the rotational axes. |
