Pfeiffer Vacuum expands the OktaLine ATEX collection

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 pressure surge resistance of PN 16, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is dominated out as a result. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial functions corresponding to vacuum furnaces or warmth treatment.
As a result of the growth of the collection, pumping speeds range from 280 to eight,a hundred m3/h. Depending on the application, there’s a selection between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This means that, successfully, the full pumping pace of the pump is on the market.
The pumps are suitable for common use due to their variable differential stress and versatile rotational speed. All pumps can be used at ambient temperatures ranging from -20 °C to + forty °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 involves stress surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. เกจวัดแรงอัดกระบอกสูบ to their magnetic coupling, there is no danger of zone entrainment. The integrated temperature sensor protects in opposition to thermal overload and monitors the fuel temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower working prices and significantly reduced maintenance costs. OktaLine Roots pumps can be operated without a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is fast and simple.
