Hermetic inert pump series

The hermetic and chemically inert series is almost universally suitable for aggressive liquids and therefore an innovation in pumping technology. Rotors and functional elements made from nickel-based tungsten carbide or ceramics like zirconia and alumina lend the pumps high chemical resistance and outstanding wear-resistance. With shaft and bearing material of hot iso-static pressed silicon carbide (SSiC) and the housing components of alloy C22 (2.4602), the pumps can be used with demanding oxidizing and reducing liquids, acids, bases and solvents. The pumps are designed hermetically and driven by a torsion-proof NdFeB magnetic coupling.
