Pfeiffer Vacuum expands the OktaLine ATEX collection

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 strain surge resistance of PN 16, they meet the very highest explosion protection necessities.
Little-known of explosive gases is ruled out as a result. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or warmth remedy.
As a result of the expansion of the collection, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the application, there is a choice between equipment category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This means that, effectively, the full pumping pace of the pump is out there.
The pumps are suitable for common use due to their variable differential strain and versatile rotational speed. All pumps can be utilized at ambient temperatures starting from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extremely low leak charges of 10-6 Pa m3/s. Controversial eliminates the need for shaft seals, which are inherently weak points if it involves stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as much as 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The integrated temperature sensor protects against thermal overload and screens the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent lower working prices and significantly reduced maintenance costs. OktaLine Roots pumps may also be operated without a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on website is quick and straightforward.
