Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 stress surge resistance of PN sixteen, they meet the very highest explosion protection necessities.
Zone entrainment of explosive gases is dominated out in consequence. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes similar to vacuum furnaces or warmth remedy.
As a result of the expansion of the series, pumping speeds range from 280 to eight,100 m3/h. Depending on the appliance, there’s a alternative between equipment class 2G or 3G. All pumps are suitable for temperature class T3. เพรสเชอร์เกจไฮดรอลิค is feasible without flame arresters. This implies that, successfully, the total pumping velocity of the pump is out there.
The pumps are appropriate for common use as a outcome of their variable differential strain and versatile rotational speed. All pumps can be utilized at ambient temperatures starting from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extraordinarily low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak factors if it comes to pressure surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and screens the fuel temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent lower operating costs and considerably reduced maintenance costs. OktaLine Roots pumps may additionally be operated with no bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors signifies that substitute on web site is fast and straightforward.
