Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect for use in processes in probably 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 sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out in consequence. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or warmth treatment.
As a results of the enlargement of the sequence, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the appliance, there’s a selection between tools class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This means that, successfully, the full pumping velocity of the pump is available.
เกจแรงดันน้ำ are appropriate for universal use because of their variable differential pressure and versatile rotational pace. 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 extraordinarily low leak charges 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 as much as 1600 kPa. Due to their magnetic coupling, there is not any threat of zone entrainment. The integrated temperature sensor protects towards thermal overload and displays the gasoline temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % decrease working prices and significantly reduced upkeep costs. OktaLine Roots pumps may also be operated with no bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on site is fast and easy.
