HiScroll ATEX Scroll Pump

They are characterized by their compact design and extremely quiet, low-vibration operation.

Pfeiffer Sized

According to Pfeiffer Vacuum (Asslar, Germany), the new pumps in the HiScroll ATEX range meet the requirements of the European directive 2014/34/EU and are marked according to ATEX II 3/-G Ex h IIC T4 Gc X +5° C ≤ Ta ≤ +40 °C. This identifies the HiScroll ATEX as suitable for pumping potentially explosive gas mixtures. Depending on the operational requirements, the ATEX directives are subdivided into different categories based on the conditions under which the pumps are allowed to operate. 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. It is even possible to pump hydrogen.

With these properties, the HiScroll ATEX covers many applications in the field of analytics, industry or research & development. 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 are characterized by their compact design and extremely quiet, low-vibration operation (<47 dB[A], in stand-by mode <42 dB[A]). They have a high water vapor tolerance, and condensation in the vacuum pump is therefore prevented from the start. The integrated two-stage gas ballast valve allows individual adjustments to be made to the process requirements.
