Pfeiffer Vacuum expands the OktaLine ATEX series

Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 16, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is dominated out in consequence. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or heat remedy.
As a result of the expansion of the sequence, pumping speeds vary from 280 to 8,100 m3/h. Depending on the appliance, there is a choice between gear class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This implies that, successfully, the total pumping pace of the pump is available.
The pumps are suitable for common use because of their variable differential stress and versatile rotational velocity. All pumps can be utilized 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 involves stress surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant as much as 1600 kPa. Due to their magnetic coupling, there is no danger of zone entrainment. The integrated temperature sensor protects towards thermal overload and displays the fuel temperature within the outlet area.
Compared to เกจวัดแรงดันน้ำ with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % decrease working prices and considerably decreased maintenance prices. OktaLine Roots pumps can be operated with no bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors signifies that alternative on site is fast and easy.
