Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent 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 necessities.
Zone entrainment of explosive gases is ruled out consequently. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or warmth therapy.
As a result of the growth of the collection, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the appliance, there’s a choice between equipment category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible without flame arresters. This signifies that, successfully, the complete pumping velocity of the pump is on the market.
The pumps are suitable for common use because of their variable differential pressure and versatile 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 obtain extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak points if it comes to strain surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as much as 1600 kPa. เกจวัดแรงดันน้ำ10บาร์ to their magnetic coupling, there is no danger of zone entrainment. The integrated temperature sensor protects towards thermal overload and displays the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease working costs and significantly decreased maintenance costs. OktaLine Roots pumps can additionally be operated without a bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors means that substitute on website is fast and simple.
