Hermetic inert pump series mzr-11557


For microreaction technology and flow chemistry The mzr-11557 micro annular gear pump of the hermetic and chemically inert series is, considering its almost universal suitability for aggressive and corrosive media, a revolution in the pump technology. Its rotors and functional elements being made of ceramics, the pump shows the highest chemical resistance and an outstanding resistance to wear. Thanks to the use of ceramics 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. Advantages High resistance to corrosion oxidizing and reducing media, acids and bases Hermetically sealed magnetic coupling (NdFeB) Long service life wear-resistant ceramic components Thermical heating optional double shell technology Chemically inert pump head alloy C22, SSiC, Al2O3 and ZrO2-ceramics High-power motor AC-motor for use with external frequency inverter Low...
