Wangen's BIO-FEED pump is designed especially for machines that would like to combine existing screw technology at the solids dispenser with the feeding of liquids. With a specially-developed milling screw, you can mix the solids that are to be added with the separately added liquid and convey it into the desired containers.

With our innovative X-LIFT quick-change system, the wearing parts are easy to replace. Only a few simple steps are needed, without this requiring disassembly of the pump from the piping system. Thereby, WANGEN BIO-FEED is also suitable for use in restricted spaces.
