Micro Annular Gear Pumps-Hermetic Inert Pump Series mzr-6355

The hermetic and chemically inert series is almost universally suitable for aggressive liquids and therefore 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 isostatic 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.

Hermetic inert pump series mzr-6355

For mini plant and micro reaction technology

The mzr-6355 micro annular gear pump of the hermetic and chemically inert series is, considering its almost universal suitability for aggressive and corrosive liquids, a revolution in the pump technology. Its rotors and functional elements being made of ceramics, the pump shows the highest chemical resistance and outstanding resistance to wear. Thanks to the use of SSiC (pressureless sintered silicon carbide) as bearing and shaft material, a magnetic coupling, and case components made out of alloy C22 (DIN 2.4602), this pump will take up any challenge in the chemical industry applications.
