Pfeiffer Vacuum expands the OktaLine ATEX sequence

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 sixteen, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is dominated out consequently. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or warmth therapy.
As a result of the enlargement of the collection, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the applying, there is a selection between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This signifies that, effectively, the complete pumping pace of the pump is on the market.
The pumps are suitable for universal use as a result of their variable differential stress and flexible rotational speed. All pumps can be utilized at ambient temperatures ranging from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extraordinarily 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 pressure surges and are high-maintenance. Undiscovered are stress surge resistant as much as 1600 kPa. Due to their magnetic coupling, there isn’t any risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and monitors the fuel temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease operating prices and significantly lowered upkeep prices. OktaLine Roots pumps may additionally be operated without a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on site is fast and simple.
