Vacuum Technology Book, Volume II Explosion-protected pumps

The ATEX series is available for processes in potentially explosive environments, or for evacuating explosive gases.

The ATEX series is available with pumping speeds between 500 m3 · h-1 and 4,000 m3 · h-1. They are PTFE sealed and made of GGG 40.3 nodular graphite cast iron. They meet the explosion protection requirements of directive 94/9/EC, category 3G, group IIB, temperature class T3 X.

Generally speaking, additional measures and / or components are required for safe pump operation, such as: startup and shutdown procedures, special backing pumps, flashback arrestors and pressure sensors. The entire system must be designed and operated in compliance with the appropriate explosion protection regulations.
