Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent for use in processes in doubtlessly 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 sixteen, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out as a result. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial functions corresponding to vacuum furnaces or heat treatment.
As a result of the expansion of the collection, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the appliance, there is a alternative between equipment class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible without flame arresters. This means that, successfully, the full pumping pace of the pump is out there.
The pumps are appropriate for universal use because of their variable differential pressure and flexible rotational speed. เครื่องมือตรวจวัดความดันเลือดเรียกว่า 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 comes to strain surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t any threat of zone entrainment. The integrated temperature sensor protects against thermal overload and monitors the gas temperature within 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 costs. OktaLine Roots pumps can be operated with no bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that substitute on site is quick and easy.
