Pfeiffer Vacuum expands the OktaLine ATEX series

Roots pumps from Pfeiffer Vacuum’s OktaLine are good 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 strain surge resistance of PN 16, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is dominated out consequently. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or heat remedy.
As a results of the growth of the sequence, pumping speeds range from 280 to 8,100 m3/h. Depending on the appliance, there’s a choice between gear category 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This means that, effectively, the full pumping speed of the pump is available.
The pumps are suitable for universal use because of their variable differential strain and flexible rotational velocity. เพรสเชอร์เกจ 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 rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak points if it involves pressure surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no danger of zone entrainment. The integrated temperature sensor protects against thermal overload and displays the fuel temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease operating costs and considerably decreased upkeep prices. OktaLine Roots pumps can also be operated without a bypass, since ATEX protection is assured even with passive rotation (windmilling). diaphragm seal of ATEX IEC motors signifies that substitute on site is fast and straightforward.
