Pfeiffer Vacuum expands the OktaLine ATEX series

Uncomplicated 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 stress surge resistance of PN 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes such as vacuum furnaces or warmth remedy.
As a results of the expansion of the series, pumping speeds vary from 280 to 8,one hundred m3/h. Depending on the application, there is a choice 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 total pumping velocity of the pump is available.
The pumps are appropriate for universal use because of their variable differential stress and flexible 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 obtain extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak factors if it comes to strain surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t a threat of zone entrainment. The built-in 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 up to 20 percent lower working prices and significantly lowered upkeep prices. OktaLine Roots pumps can 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 website is quick and straightforward.
