Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 safety necessities.
Zone entrainment of explosive gases is ruled out consequently. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or heat treatment.
As a result of the growth of the collection, pumping speeds vary from 280 to eight,100 m3/h. Depending on the appliance, there is a alternative between gear category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible without flame arresters. This means that, successfully, the full pumping speed of the pump is on the market.
The pumps are appropriate for universal use due to their variable differential stress and flexible rotational pace. All pumps can be utilized at ambient temperatures starting from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain 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 pressure surges and are high-maintenance. Deadline are stress surge resistant as much as 1600 kPa. Due to their magnetic coupling, there is not any risk of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and screens the gasoline temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % lower operating prices and significantly decreased upkeep costs. OktaLine Roots pumps may also be operated without a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that alternative on site is quick and straightforward.
