Roots pumps from Pfeiffer Vacuum’s OktaLine are best 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 stress surge resistance of PN sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is dominated out consequently. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or warmth treatment.
As a results of the enlargement of the collection, pumping speeds range from 280 to eight,one hundred m3/h. Depending on เกจวัดความดันแก๊ส , there is a selection between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible without flame arresters. This signifies that, effectively, the complete pumping speed of the pump is on the market.
The pumps are appropriate for common use due to their variable differential strain and flexible rotational velocity. All pumps can be used at ambient temperatures ranging from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain 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 stress surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there is no danger of zone entrainment. The integrated temperature sensor protects towards thermal overload and screens the gas temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % decrease operating prices and considerably decreased maintenance costs. OktaLine Roots pumps can also be operated without a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that substitute on site is quick and easy.
