Roots pumps 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 safety requirements.
Zone entrainment of explosive gases is dominated out consequently. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial functions corresponding to vacuum furnaces or heat treatment.
As a result of the expansion of the collection, pumping speeds range from 280 to eight,100 m3/h. Depending on the appliance, there is a selection between tools category 2G or 3G. All pumps are appropriate for temperature class T3. เครื่องมือที่ใช้วัดความดันคือ is possible without flame arresters. This implies that, effectively, the total pumping velocity of the pump is available.
The pumps are suitable for common use as a outcome of their variable differential pressure and versatile rotational speed. All pumps can be utilized at ambient temperatures starting from -20 °C to + forty °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 pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant as much as 1600 kPa. Due to their magnetic coupling, there is no threat of zone entrainment. The built-in temperature sensor protects towards 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 % lower operating prices and significantly decreased maintenance costs. OktaLine Roots pumps may additionally 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 site is fast and easy.
