Pfeiffer Vacuum expands the OktaLine ATEX collection

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 sixteen, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out as a result. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial functions corresponding to vacuum furnaces or heat therapy.
As a results of the enlargement of the sequence, pumping speeds range from 280 to 8,100 m3/h. Depending on the application, 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 means that, effectively, the complete pumping speed of the pump is on the market.
The pumps are suitable for universal use as a outcome of their variable differential stress and flexible rotational pace. 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 charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak factors if it comes to stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as much as 1600 kPa. Due to their magnetic coupling, there isn’t any risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and displays the gas temperature in the outlet space.
Compared to ไดอะแฟรม ซีล with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % lower operating costs and considerably lowered maintenance prices. OktaLine Roots pumps may additionally be operated with no bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is fast and easy.
