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 stress surge resistance of PN 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is dominated out in consequence. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or warmth remedy.
As a result of the expansion of the sequence, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the applying, there is a choice between gear category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This implies that, successfully, the complete pumping speed of the pump is out there.
The pumps are suitable for universal use due to their variable differential stress and versatile rotational pace. All pumps can be utilized at ambient temperatures ranging from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extremely low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak points if it comes to strain surges and are high-maintenance. หลักการทำงานของเกจ์วัดแก๊ส are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not any risk of zone entrainment. The built-in temperature sensor protects towards thermal overload and monitors the fuel temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % lower working prices and significantly lowered upkeep costs. OktaLine Roots pumps may also be operated with no bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on website is fast and straightforward.
