Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 safety requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or heat treatment.
As a result of the expansion of the series, pumping speeds range from 280 to eight,a hundred m3/h. Depending on the application, there’s a alternative between equipment class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This implies that, effectively, the full pumping pace of the pump is out there.
The pumps are suitable for universal use due to their variable differential strain and versatile rotational speed. Results can be utilized at ambient temperatures ranging from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extremely low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak points if it involves strain surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t a threat of zone entrainment. Effortless built-in temperature sensor protects towards thermal overload and displays the fuel temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease operating costs and significantly decreased upkeep prices. OktaLine Roots pumps may additionally be operated with no bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on website is quick and easy.
