Roots pumps from Pfeiffer Vacuum’s OktaLine are best 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 pressure surge resistance of PN 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is dominated out consequently. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or warmth therapy.
As a results of the expansion of the collection, pumping speeds vary from 280 to 8,100 m3/h. Depending on the applying, there is a selection between tools class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This means that, effectively, the total pumping speed of the pump is out there.
The pumps are suitable for common use as a end result of their variable differential stress and flexible rotational velocity. All pumps can be utilized at ambient temperatures starting from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, that are inherently weak factors if it involves stress 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 not any threat of zone entrainment. The integrated temperature sensor protects against thermal overload and monitors the gasoline temperature in the outlet space.
Compared to เกจวัดแรงดันราคา with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease working costs and considerably decreased maintenance costs. OktaLine Roots pumps can also be operated and not using a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is fast and easy.
