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 safety requirements.
Zone entrainment of explosive gases is ruled out as a result. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or heat therapy.
As a results of the enlargement of the sequence, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on เกจวัดแรงดันปั๊มลม , there is a selection between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This signifies that, effectively, the total pumping velocity of the pump is on the market.
The pumps are appropriate for common use because of their variable differential pressure and flexible rotational speed. All pumps can be used at ambient temperatures starting from -20 °C to + 40 °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 need for shaft seals, that are inherently weak points if it involves strain surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not any threat of zone entrainment. The built-in temperature sensor protects against thermal overload and monitors the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent lower working costs and significantly decreased upkeep prices. OktaLine Roots pumps may also be operated with no bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on web site is quick and simple.
