Pfeiffer Vacuum expands the OktaLine ATEX series

Roots pumps from Pfeiffer Vacuum’s OktaLine are good for use in processes in doubtlessly 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 protection necessities.
Zone entrainment of explosive gases is dominated out consequently. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or heat therapy.
As a result of the growth of the series, pumping speeds vary from 280 to eight,100 m3/h. Depending on the appliance, there is a selection between gear category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This implies that, effectively, the full pumping speed of the pump is on the market.
The pumps are suitable for universal use because of their variable differential pressure and versatile rotational velocity. 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 achieve extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak factors if it comes to pressure surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there isn’t any danger of zone entrainment. pressure gauge 4 นิ้ว built-in temperature sensor protects towards thermal overload and monitors the gasoline temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower operating prices and significantly decreased upkeep prices. OktaLine Roots pumps may also be operated with no bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on website is fast and easy.
