Self-priming pump Type WANGEN BIO-FEED

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.

Due to the pushing of the screw connection, WANGEN BIO-FEED turns into a high-performance
suction pump. You can use it as a central pump in your biogas plant.

To simplfy integration into your conveyor, our WANGEN BIO-FEED's pump body is equipped with two DN150 connections bearing bracket side, one DN400 connection for the screw conveyor and two DN200 at stator side. In addition, you can use these as cleaning openings and for rinsing the mixing chamber.
