Abstract

The present invention relates to a diverter for a feed-out arrangement for a pulp treatment vessel such as a digester or an impregnation vessel, wherein the diverter comprises a body having an upper end and a lower end, the lower end having a larger radial extension than the upper end, and also comprising at least one blade extending at least partly in a radial direction, said blade being arranged at the lower end of the body. The invention also comprises a feed-out arrangement comprising such a diverter.
