Roots pumps from Pfeiffer Vacuum’s OktaLine are best 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 sixteen, they meet the very highest explosion protection requirements.
เพรสเชอร์เกจ of explosive gases is dominated out consequently. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or warmth therapy.
As a results of the expansion of the sequence, pumping speeds range from 280 to eight,one hundred m3/h. Depending on the appliance, there’s a selection between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This signifies that, successfully, the full pumping speed of the pump is available.
The pumps are appropriate for common use due to their variable differential pressure and versatile rotational pace. 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 charges of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak factors if it involves 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 a danger of zone entrainment. The integrated temperature sensor protects in opposition to thermal overload and displays the gasoline temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % decrease operating prices and significantly reduced upkeep costs. OktaLine Roots pumps can be operated and not using a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that alternative on web site is fast and simple.
