Centrifugal pumps

The low friction of BALINIT® MILUBIA improves the durability of ceramic shafts and bearings enhancing the efficiency and reliability of the pumps.

BALINIT® NALUBIA has a very low friction and high wear resistance. In dry running the surface temperature of coated seal rings remains low and damages of the seal rings is prevented.
