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 vapors. 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 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.
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 minimizes pump wear and extends maintenance intervals. The proven Pfeiffer Vacuum quality due to high-quality, durable components ensures a long lifetime, low operating costs and reduced environmental impact. 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.
The powerful yet efficient drive is characterized by a 15% higher efficiency compared to conventional drives. This enables maximum performance at low temperatures and easier and more cost-effective cooling.
Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal for use in processes in potentially explosive environments or for evacuating explosive gases. Designed in accordance with the ATEX Directive (2014/34/EU1 and/or 1999/92/EC) with pressure surge resistance of PN 16, they meet the very highest explosion protection requirements.
Pfeiffer Vacuum, one of the world’s leading providers of vacuum and leak detection solutions for the semiconductor as well as the analytical, industrial and research & development markets, opened up a new 40,000 square foot facility on May 13th. This state-of-the-art facility is located at 4037 Guion Lane, Indianapolis, Indiana.
Pfeiffer Vacuum Technology AG today announced results for the first quarter 2022. The Company’s sales increased by 12.7% to EUR 216.0 million, the first time in the Company’s history to achieve over EUR 200 million in sales within one quarter (Q1 2021: EUR 191.7 million).
Pfeiffer Vacuum Technology AG reported the audited financial results for the fiscal year 2021. The Company reported record sales of EUR 771.4 million, an operating result (EBIT) of EUR 93.1 million as well as an EBIT margin of 12.1%.
Pfeiffer Vacuum is introducing new compact Roots pumps with high pumping speeds. These Roots pumps from the HiLobe series cover a wide range of applications that call for large chambers to be evacuated rapidly.
Valve manufacturer GEMÜ is expanding its product range for automation components in the processing industry. The new electrical position indicators GEMÜ 1240, 1241 and 1242 and the combi switchboxes GEMÜ 4240, 4241 and 4242 will ensure reliable recording of valve end positions and form the basis for successful process automation – even in potentially explosive areas.
