Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal 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 sixteen, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or warmth treatment.
As a result of the enlargement of the collection, pumping speeds vary from 280 to 8,100 m3/h. Depending on the appliance, there’s a alternative between gear class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This implies that, effectively, the total pumping pace of the pump is on the market.
The pumps are suitable for common use as a result of their variable differential stress and flexible rotational speed. 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 extraordinarily low leak rates of 10-6 Pa m3/s. weksler ea14 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 strain surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there is no danger of zone entrainment. The integrated temperature sensor protects in opposition to thermal overload and displays the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % decrease operating prices and significantly decreased maintenance prices. OktaLine Roots pumps can additionally be operated without a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is fast and easy.
