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 stress surge resistance of PN sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out as a result. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or heat remedy.
As a results of the expansion of the collection, pumping speeds range from 280 to 8,100 m3/h. Depending on the appliance, there is a choice between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This means that, successfully, the complete pumping pace of the pump is out there.
The pumps are suitable for common use because of their variable differential stress and versatile rotational velocity. 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 obtain extraordinarily low leak charges of 10-6 Pa m3/s. เกจวัดแรงดันอากาศ eliminates the need for shaft seals, which are inherently weak points if it involves pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant as much as 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 gasoline temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % lower operating prices and significantly decreased maintenance costs. OktaLine Roots pumps may also be operated and not using a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that substitute on web site is fast and simple.
