Hermetically sealed and absolutely leak-free centrifugal pumps for aggressive and other liquids. All components getting in touch with the media are made of an acid resistant synthetic material without fiber or other filler.
High-efficiency ratio: precisely milled and closed impellers in an adjusted 3D spiral housing.
Reliable thanks to extra large hydrodynamic bearings with axial guidance, additional wetting, and balancing of axial thrust. The axles are not susceptible to interferences and are built of few pieces only reducing the eventual need of spare parts.
All safety-related components are crafted of stress-free mounted plastic plates which make them especially dimensionally stable. The engine is protected by an additional acid-resistant protective coating.
