เครื่องมือวัดpressure 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 strain surge resistance of PN 16, they meet the very highest explosion protection necessities.
Zone entrainment of explosive gases is ruled out as a result. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or warmth therapy.
As a result of the expansion of the collection, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the appliance, there’s a alternative between gear class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible with out flame arresters. This implies that, effectively, the complete pumping pace of the pump is on the market.
The pumps are appropriate for universal use due to their variable differential stress and versatile rotational speed. 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 achieve extraordinarily low leak rates 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 stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a danger of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and displays the gas temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease operating costs and significantly lowered upkeep prices. OktaLine Roots pumps can be operated without a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on website is quick and straightforward.
