Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent 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 pressure surge resistance of PN 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or warmth remedy.
As a results of the expansion of the collection, pumping speeds range from 280 to eight,a hundred m3/h. Depending on เกจวัดแรงดันลมดิจิตอล applying, there is a alternative between tools class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible with out flame arresters. This signifies that, effectively, the full pumping pace of the pump is out there.
The pumps are suitable for universal use because of their variable differential stress and versatile rotational velocity. All pumps can be utilized at ambient temperatures ranging from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extraordinarily 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 up to 1600 kPa. Due to their magnetic coupling, there is no threat of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and monitors the fuel temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease operating costs and significantly lowered maintenance prices. OktaLine Roots pumps can be operated with no bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that substitute on web site is fast and simple.
