Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent 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 strain surge resistance of PN 16, they meet the very highest explosion safety requirements.
เครื่องมือที่ใช้วัดความดัน of explosive gases is ruled out as a result. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or warmth treatment.
As a results of the expansion of the collection, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the appliance, there’s a selection between tools class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This implies that, successfully, the complete pumping speed of the pump is on the market.
The pumps are suitable for universal use due to their variable differential strain and flexible rotational speed. All pumps can be used at ambient temperatures starting from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain 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 comes to stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and monitors the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent decrease working prices and considerably reduced maintenance prices. OktaLine Roots pumps can additionally be operated and not utilizing a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on web site is fast and easy.
