เพรสเชอร์เกจลม from Pfeiffer Vacuum’s OktaLine are ideal 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 pressure surge resistance of PN 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or heat treatment.
As a result of the growth of the collection, pumping speeds range from 280 to eight,a hundred m3/h. Depending on the applying, there’s a alternative between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This means that, effectively, the total pumping speed of the pump is out there.
The pumps are suitable for common use as a result of their variable differential strain and versatile rotational velocity. All pumps can be utilized at ambient temperatures starting from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extremely low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak factors if it involves pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there is not a risk of zone entrainment. The built-in temperature sensor protects against thermal overload and monitors the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent lower operating prices and considerably decreased upkeep prices. OktaLine Roots pumps can be operated with no bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on website is quick and straightforward.
