Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent for use in processes in probably explosive environments or for evacuating explosive gases. Designed in accordance with the ATEX Directive (2014/34/EU1 and/or 1999/92/EC) with stress surge resistance of PN sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out consequently. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or warmth therapy.
As a result of the expansion of the collection, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the applying, there’s a selection between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This means that, successfully, the full pumping velocity of the pump is out there.
The pumps are suitable for common use as a result of their variable differential pressure and versatile rotational speed. All pumps 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 achieve extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak factors if it involves pressure surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as much as 1600 kPa. Due to their magnetic coupling, there is not a threat of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and monitors the fuel temperature within the outlet space.
Compared to เครื่องมือความดัน with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % lower working prices and significantly reduced upkeep costs. OktaLine Roots pumps may also be operated and not using a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on web site is fast and simple.
