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 sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is dominated out consequently. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or warmth treatment.
As a results of the enlargement of the collection, pumping speeds range from 280 to eight,one hundred m3/h. Depending on the appliance, there is a selection between gear class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible with out flame arresters. This implies that, successfully, the total pumping velocity of the pump is on the market.
The pumps are suitable for common use due to their variable differential stress and versatile 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 achieve extremely low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, which are inherently weak points if it comes to pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not any risk of zone entrainment. The built-in temperature sensor protects towards thermal overload and screens the gas temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower operating costs and considerably decreased maintenance prices. digital pressure gauge may also be operated and not using a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors means that alternative on site is quick and simple.
