Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal 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 16, 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 therapy.
As a result of the expansion of the sequence, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the appliance, there is a choice between gear category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This implies that, successfully, the full pumping pace of the pump is out there.
เครื่องมือความดัน are appropriate for common use as a outcome of their variable differential stress and flexible 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 need for shaft seals, that are inherently weak points if it comes to pressure surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there isn’t any danger of zone entrainment. The integrated temperature sensor protects against thermal overload and displays the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % decrease operating costs and considerably lowered maintenance prices. OktaLine Roots pumps may additionally be operated with no bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on web site is fast and simple.
