1. Device for the sterilization of fluid media by means of UV radiation, comprising a pump line having a mid-axis, a radial plane perpendicular to the mid-axis, and a sidewall, by means of which the fluid media can be taken up and discharged along a plurality of possible flow paths collectively having a flow direction, wherein the sidewall is passed through by a number of UV-transparent sheath pipes in which UV radiators are arranged for the emission of UV radiation into the pump line, said sheath pipes comprising at least a first group of sheaths and a second group of sheaths, each group comprising a series of sheaths helically arranged one behind another in the flow direction of the pump line, with each adjacent sheath in the series circumferentially offset by an angle α in relation to one another, the first group of sheaths having midpoints that pass through a first helical path winding about the mid-axis of the pump line, each sheath of the first group disposed at a first non-zero angle β1 relative to the radial plane, and the second group of sheaths having midpoints that pass through a second helical path, which differs from the first helical path, and each sheath of the second group disposed at a second non-zero angle β2 relative to the radial plane different than the first angle β1. |
