Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent for use in processes in doubtlessly explosive environments or for evacuating explosive gases. Designed in accordance with the ATEX Directive (2014/34/EU1 and/or 1999/92/EC) with stress surge resistance of PN 16, they meet the very highest explosion protection necessities.
Zone entrainment of explosive gases is dominated out in consequence. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial purposes such as vacuum furnaces or warmth treatment.
As a results of the expansion of the series, pumping speeds vary from 280 to eight,one hundred 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 possible without flame arresters. This signifies that, effectively, the complete pumping speed of the pump is available.
The pumps are suitable for universal use because of their variable differential pressure and flexible rotational velocity. All pumps can be used at ambient temperatures starting from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, which are inherently weak factors if it involves pressure surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there isn’t any threat of zone entrainment. The integrated temperature sensor protects against thermal overload and displays the gasoline temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease working prices and considerably reduced upkeep prices. OktaLine Roots pumps can be operated and not utilizing a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). pressure gauge ยี่ห้อ tk of ATEX IEC motors signifies that alternative on site is fast and simple.
