Roots pumps from Pfeiffer Vacuum’s OktaLine are best 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 necessities.
Zone entrainment of explosive gases is ruled out consequently. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or heat treatment.
As a results of the growth of the collection, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the applying, there is a selection between tools class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible with out flame arresters. This signifies that, effectively, the total pumping velocity of the pump is out there.
The pumps are suitable for universal use because of their variable differential strain 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 rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, that are inherently weak points if it involves pressure 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 threat of zone entrainment. เกจวัดแรงดันไทวัสดุ integrated temperature sensor protects in opposition to thermal overload and screens the fuel 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 reduced upkeep costs. OktaLine Roots pumps can be operated and not utilizing a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors means that alternative on website is fast and easy.
