Chemistry Diaphragm Vacuum Pumps with ATEX compliance

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 ATEX approval includes the interior of the pump (in contact with pumped gases) as well as the surrounding area of the pump.

• Outstanding chemical resistance and superior vapor tolerance
• Mainly made of antistatic materials
• Flame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supply
• Overpressure safety relief valves internally and at outlet
• With separate gas ballast connection part for use of inert gas
• Safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage

ATEX compliance:
Pump chamber (pumped gases): II 2G IIC T3 X
Exterior space (pump environment): II 2G IIB T4 X (with inert gas purging) / II 3G IIB T4 X (without inert gas purging)
