Pfeiffer Vacuum expands the OktaLine ATEX series

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 16, they meet the very highest explosion protection necessities.
Zone entrainment of explosive gases is dominated out as a result. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial purposes similar to vacuum furnaces or warmth therapy.
As a result of the expansion of the sequence, pumping speeds vary from 280 to 8,one hundred m3/h. Depending on the applying, there is a alternative between tools class 2G or 3G. All pumps are appropriate for temperature class T3. Factors is feasible with out flame arresters. This implies that, effectively, the full pumping pace of the pump is on the market.
The pumps are suitable for common use because of their variable differential stress 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 extremely 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 involves pressure surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there is no danger of zone entrainment. The integrated temperature sensor protects towards thermal overload and displays the fuel temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent lower operating costs and considerably reduced upkeep costs. OktaLine Roots pumps may also be operated and not utilizing a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is quick and straightforward.
