Pfeiffer Vacuum expands the OktaLine ATEX sequence

Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal for use in processes in potentially 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 safety 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 results of the enlargement of the sequence, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the applying, there’s a choice between gear category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible with out flame arresters. This implies that, successfully, the full pumping speed of the pump is out there.
pressure gauge ด้าน ดูด are appropriate for universal use due to their variable differential strain and versatile rotational velocity. All pumps can be used at ambient temperatures ranging from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extremely low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, which are inherently weak factors if it involves stress surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The built-in temperature sensor protects towards thermal overload and monitors the gas temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease operating prices and considerably lowered 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 signifies that substitute on website is quick and easy.
