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 strain surge resistance of PN 16, they meet the very highest explosion safety requirements.

As a results of the enlargement of the sequence, pumping speeds range from 280 to 8,100 m3/h. Depending on the appliance, there is a selection between gear class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This means that, successfully, the complete pumping velocity of the pump is available.
The pumps are appropriate for common use due to their variable differential pressure and flexible rotational speed. All pumps can be used at ambient temperatures ranging from -20 °C to + 40 °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 factors if it involves strain surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t any risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and screens the gasoline temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease operating prices and considerably lowered upkeep costs. OktaLine Roots pumps can be operated and not utilizing a bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that alternative on site is fast and easy.
