Pfeiffer Vacuum expands the OktaLine ATEX series

Roots pumps from Pfeiffer Vacuum’s OktaLine are best 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 protection necessities.
Zone entrainment of explosive gases is dominated out in consequence. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or heat remedy.
As a result of the enlargement of the collection, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the applying, there’s a choice between equipment class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This signifies that, successfully, the full pumping velocity of the pump is out there.
The pumps are suitable for universal use because of their variable differential pressure and versatile rotational speed. 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 extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, which are inherently weak points if it comes to strain surges and are high-maintenance. เกจวัดแรงดันไนโตรเจน are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a risk of zone entrainment. The built-in temperature sensor protects towards thermal overload and displays the gasoline temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease working costs and considerably decreased maintenance costs. OktaLine Roots pumps can additionally be operated with no bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that alternative on web site is quick and simple.
