MZ 2C EX

Description

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
