Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are good 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 pressure surge resistance of PN 16, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out in consequence. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or heat therapy.
As a results of the expansion of the sequence, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the applying, there’s a selection between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This implies that, effectively, the complete pumping speed of the pump is out there.
The pumps are appropriate for universal use as a outcome of their variable differential strain 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 need for shaft seals, which are inherently weak points if it involves strain surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t any risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and screens the fuel temperature within the outlet space.
Compared to เกจวัดแรงดัน with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease working prices and considerably decreased upkeep prices. OktaLine Roots pumps can additionally be operated and not utilizing a bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that replacement on website is fast and simple.
