Hermetic inert pump series mzr-7255

Beschreibung

For mini plant and microreaction technology The mzr-7255 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 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. Advantages High resistance to corrosion oxidizing and reducing media, acids and bases Long service life wear-resistant ceramic components Hermetically sealed magnetic coupling (NdFeB) Compact, chemically inert pump head 146 mm long, alloy C22, SSiC, Al2O3 and ZrO2-ceramics Precision motor and user-friendly control dynamic DC-servomotor with encoder...
