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 16, they meet the very highest explosion protection requirements.
เกจวัดแรงดันpsi of explosive gases is ruled out consequently. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or warmth remedy.
As a result of the growth of the sequence, pumping speeds range from 280 to 8,one hundred m3/h. Depending on the appliance, there’s a choice between tools class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This signifies that, effectively, the full pumping velocity of the pump is available.
The pumps are suitable for common use as a result of their variable differential strain and versatile rotational speed. All pumps can be utilized 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 need for shaft seals, that are inherently weak factors if it involves stress surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant as much as 1600 kPa. Due to their magnetic coupling, there isn’t any danger of zone entrainment. The integrated temperature sensor protects towards thermal overload and monitors the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease operating prices and considerably reduced upkeep costs. OktaLine Roots pumps can additionally be operated without a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on website is fast and straightforward.
