The new pumps in Pfeiffer Vacuum’s HiScroll ATEX range have an explosion-proof interior and are designed for pumping potentially explosive gases within the analytics, industry or research and development sectors.
The HiScroll ATEX conforms to equipment category 3G based on contact with the pumped substance and meets temperature class T4. This allows all gases up to and including explosion group IIC to be pumped and it is also possible to pump hydrogen.
Explosion-protected devices are used in many sectors, including in industrial processes such as generating and pumping hydrogen. The HiScroll ATEX is also used in laboratories for pumping solvent-based liquids and gases which can produce combustible vapours. The ATEX certification is awarded because the HiScroll ATEX has no sources of ignition for potentially hazardous gas mixtures.
Pfeiffer Vacuum scroll pumps offer high pumping speeds during pump-down, even at atmospheric pressure. The completely dry and hermetically sealed vacuum pumps achieve a nominal pumping speed of 6 to 20 m³/h. They have a compact design and quiet, low-vibration operation (<47 dB[A], in stand-by mode <42 dB[A]).
