There is a risk of explosion wherever combustible dusts, gases or vapors are produced or used. The Okta ATEX Roots pumps and the HiScroll ATEX scroll pumps from Pfeiffer Vacuum are suitable solutions for potentially explosive atmospheres.
Explosion-proof Okta ATEX Roots pumps
In accordance with the European ATEX Directive (2014/34/EU or 1999/92/EC) and by complying with the pressure surge resistance according to PN 16, the Okta ATEX Roots pumps meet the highest requirements for explosion protection. The hermetically sealed magnetic coupling on the drive shaft prevents zone entrainment. Thanks to the variable differential pressure and the wide usable speed range, the Okta can be used universally - in ambient temperatures from -20 °C to +40 °C. A magnetic coupling makes it hermetically sealed and results in low leakage rates of 10-6 Pam3/s.
Explosion-proof scroll pumps HiScroll ATEX
The pumps in the HiScroll ATEX series meet the requirements of European Directive ATEX 2014/34/EU and 1999/92/EC and are therefore suitable for pumping potentially explosive gases. They comply with both equipment category 3G for the wetted area and temperature class T4. All gases up to and including explosion group IIC can be pumped. Even pumping hydrogen is possible.
High pumping speed even from atmospheric pressure
Scroll pumps from Pfeiffer Vacuum offer a high pumping speed from atmospheric pressure. The completely oil-free vacuum pumps have a compact design and are characterized by particularly quiet and low-vibration operation. The powerful and efficient drive is characterized by up to 15 % higher efficiency compared to conventional drives. The maintenance requirements are low.
