Ex-pump for application in chemical and process technology

The micro annular gear pump mzr-6359X2 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 pumps are 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.
