เกจวัดแรงดันไนโตรเจน from Pfeiffer Vacuum’s OktaLine are perfect for use in processes in probably 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 safety requirements.
Zone entrainment of explosive gases is dominated out consequently. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or heat therapy.
As a result of the growth of the series, pumping speeds range from 280 to eight,100 m3/h. Depending on the applying, there’s a choice between equipment class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This signifies that, effectively, the full pumping speed of the pump is available.
The pumps are appropriate for common use because of their variable differential stress and flexible rotational speed. All pumps can be used at ambient temperatures ranging from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extremely 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 stress surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The built-in temperature sensor protects towards thermal overload and displays the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower operating costs and significantly reduced maintenance prices. OktaLine Roots pumps can also 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 site is fast and simple.
