Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent 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 stress surge resistance of PN sixteen, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or heat treatment.
As a results of the enlargement of the series, pumping speeds range from 280 to 8,100 m3/h. Depending on the appliance, there’s a selection between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible without flame arresters. This means that, successfully, the full pumping speed of the pump is out there.
The pumps are suitable for common use due to their variable differential strain and versatile rotational velocity. All pumps can be utilized 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. เกจวัดแรงดันnuovafima eliminates the need for shaft seals, that are inherently weak factors if it comes to stress surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there is no danger of zone entrainment. The built-in temperature sensor protects towards 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 percent decrease operating prices and considerably reduced upkeep prices. OktaLine Roots pumps can additionally be operated and not utilizing a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that substitute on website is fast and straightforward.
