Pfeiffer Vacuum introduced its HiScroll Series ATEX scroll pumps designed for pumping potentially explosive gas mixtures up to and including explosion group IIC. These scroll pumps 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.
HiScroll ATEX has no sources of ignition for potentially hazardous gas mixtures and are ideal for use in analytics, laboratories, industry, and research & development where combustible vapors are produced.
These ATEX 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 deliver an 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.
The integrated safety valve and self-regulating operation of the pump guarantee its safe operation.
The pump’s drive delivers a 15 % higher efficiency compared to conventional drives. This enables maximum performance at low temperatures and easier and more cost-effective cooling.
