Pfeiffer Vacuum expands the OktaLine ATEX sequence

Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 16, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is ruled out as a result. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or heat therapy.
As a result of the enlargement of the sequence, pumping speeds range from 280 to 8,100 m3/h. Depending on the application, there is a alternative between equipment category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible without flame arresters. This signifies that, effectively, the total pumping pace 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 + 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, that are inherently weak points if it involves 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 integrated temperature sensor protects towards thermal overload and displays the gasoline temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % lower working prices and considerably decreased maintenance costs. OktaLine Roots pumps can be operated without a bypass, since ATEX safety is assured even with passive rotation (windmilling). pressure gauge ลม of ATEX IEC motors means that alternative on website is quick and simple.
