Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 16, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is ruled out in consequence. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes corresponding to vacuum furnaces or warmth remedy.
As a results of the expansion of the collection, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on pressure gauge หน้าปัด 2 นิ้ว applying, there’s a alternative between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This signifies that, effectively, the full pumping pace of the pump is on the market.
The pumps are suitable for common use due to their variable differential pressure and versatile rotational velocity. 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 charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity 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 no risk of zone entrainment. The built-in temperature sensor protects against thermal overload and screens the gas temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % decrease working prices and significantly lowered maintenance prices. OktaLine Roots pumps may additionally be operated and not using a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on web site is quick and easy.
