The new F 728 series from FLUX-GERÄTE GMBH is a new generation of centrifugal immersion pumps. The pumps are characterised by their intelligent modular construction which is incredibly easy to adapt to any form of use. For example, the series is totally safe to run dry to an immersion length of 600 mm without a bearing in the fluid area and is robust in the face of contamination in fluids. On the other hand, an immersion length of up to 1800 mm can be achieved by fitting a bush bearing. The pump housing is designed as a spiral, ensuring very good efficiency and a high pump capacity.
