Pfeiffer Introduces ATEX Scroll Pump

News

New range is suitable for pumping potentially explosive gas mixtures

Pfeiffer Vacuum has announced that new pumps in its 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 +5degC ≤ Ta ≤ +40degC. 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. 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 since 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 are characterised by their compact design and quiet, low-vibration operation (<47 dB[A], in stand-by mode <42 dB[A]). They have a high water vapour 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.

The pumps can be easily connected to other Pfeiffer Vacuum products, such as turbopumps, via RS-485, EtherCat or ProfiNet and can be operated with a higher-level controller or a PC. The intelligent interface enables use of the RPM regulator or the innovative stand-by mode, which allows the pump to be optimally adjusted and operated for the application. At the same time, this minimises pump wear and extends maintenance intervals. According to the compay, easy maintenance of the pumps enables not only shorter service times but also maximum availability. The integrated safety valve and self-regulating operation of the pump guarantee its safe operation.

A powerful yet efficient drive is characterised by a 15 percent higher efficiency compared to conventional drives. This enables maximum performance at low temperatures and easier and more cost-effective cooling.
