Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 protection necessities.
Zone entrainment of explosive gases is dominated out as a result. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or heat remedy.
As a results of the enlargement of the sequence, pumping speeds range from 280 to eight,100 m3/h. Depending on the applying, there is a alternative between equipment class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This means that, successfully, the full pumping velocity of the pump is out there.
The pumps are suitable for common use as a outcome of their variable differential pressure and versatile rotational pace. 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 extremely low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, which are inherently weak points if it involves strain surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The integrated temperature sensor protects in opposition to thermal overload and monitors the gasoline temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent decrease operating prices and significantly lowered maintenance prices. digital pressure gauge ราคา can be operated and not using a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors signifies that replacement on web site is fast and simple.
