Roots pumps from Pfeiffer Vacuum’s OktaLine are good 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 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is dominated out as a result. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or warmth therapy.
As a result of the growth of the collection, pumping speeds range from 280 to 8,one hundred m3/h. Depending on the application, there’s a choice between gear category 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible with out flame arresters. This means that, effectively, the full pumping speed of the pump is out there.
The pumps are suitable for universal use as a outcome of their variable differential stress and flexible rotational velocity. 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 extraordinarily low leak rates 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. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a threat of zone entrainment. pressure gauge ลม integrated temperature sensor protects in opposition to thermal overload and screens the fuel temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent lower working costs and considerably reduced upkeep costs. OktaLine Roots pumps can also be operated without a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that substitute on website is fast and easy.
