Pfeiffer Vacuum expands the OktaLine ATEX sequence

Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 stress surge resistance of PN 16, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is dominated out consequently. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or warmth treatment.
As a result of the enlargement of the collection, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the application, there is a selection between equipment class 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 pace of the pump is on the market.
The pumps are suitable for universal use due to their variable differential pressure and versatile rotational speed. All pumps can be used at ambient temperatures starting from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extremely low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak factors if it comes to pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not any risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and screens the gas temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent lower working prices and considerably decreased maintenance costs. เพรสเชอร์เกจnuovafima may additionally be operated with no bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is quick and straightforward.
