Refund from Pfeiffer Vacuum’s OktaLine are excellent 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 sixteen, they meet the very highest explosion protection necessities.
Zone entrainment of explosive gases is dominated out in consequence. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes similar to vacuum furnaces or warmth treatment.
As a results of the enlargement of the sequence, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the applying, there’s a choice between tools category 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This means that, effectively, the total pumping velocity of the pump is available.
The pumps are appropriate for common use due to their variable differential strain and flexible 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 extremely low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity 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 as much as 1600 kPa. Due to their magnetic coupling, there is not any risk of zone entrainment. The integrated temperature sensor protects in opposition to thermal overload and displays the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % decrease operating costs and considerably decreased maintenance costs. OktaLine Roots pumps can additionally be operated and not utilizing a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that substitute on site is quick and straightforward.
