Ex-versions mzr-7259 Ex

Beschreibung

Ex-pump for application in chemical and process technology The micro annular gear pump mzr-7259 Ex of the hermetic inert pump series in its explosion proof version is used for highly precise, low pulsation small volume dosage even of aggressive and corrosive liquids. The compact design combined with high achievable pressures are unique features. The pump is applied in the field of chemical and process technology. Thanks to the use of rotors and functional elements being made of ceramics, a magnetic coupling, and case components made out of alloy C22, this pump will take up any challenge in the chemical industry applications. Advantages Ex-certification ATEX conform with EU Directive 2014/34/EU Compact, chemically inert length 280 mm, alloy C22, SSiC, Al2O3 and ZrO2 ceramics Long service life wear-resistant ceramic components Hermetically sealed magnetic coupling (NdFeB) High dosage precision precision CV < 1 % at low volumes Low pulsation delivery, low shear stress rotary micro...
