MZ 2C EX
ATEX chemistry diaphragm pumps offer all advantages of oil-free chemistry diaphragm pumps. Typical applications are rotary evaporators and drying ovens with potentially explosive atmospheres. The pumps are mainly made of antistatic materials. Included in delivery is a separate gas ballast connection part for use of inert gas.
Performance features
- outstanding chemical resistance and superior vapor tolerance
- flame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supply
- no technically demanding over current protection by customer necessary
- overpressure safety relief valve at outlet
- safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage
