Pfeiffer Vacuum expands the OktaLine ATEX series

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 pressure surge resistance of PN sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out in consequence. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes corresponding to vacuum furnaces or warmth treatment.
As a result of the growth of the sequence, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the appliance, there’s a selection between equipment class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This means that, successfully, the total pumping velocity of the pump is out there.
The pumps are appropriate for universal use due to their variable differential stress 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 rates of 10-6 Pa m3/s. pressure gauge 10 bar eliminates the need for shaft seals, which are inherently weak points if it comes to stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as much as 1600 kPa. pressure gauge octa to their magnetic coupling, there is no threat of zone entrainment. The built-in temperature sensor protects towards thermal overload and screens the gasoline temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent lower working costs and considerably reduced maintenance costs. OktaLine Roots pumps can be operated without a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on website is fast and straightforward.
