Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal 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 requirements.
Zone entrainment of explosive gases is dominated out as a result. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or warmth therapy.
As a results of the growth of the collection, pumping speeds range from 280 to eight,100 m3/h. Depending on the appliance, there’s a selection between equipment category 2G or 3G. เกจวัดอาร์กอน are appropriate for temperature class T3. Installation is possible without flame arresters. This implies that, effectively, the full pumping velocity of the pump is on the market.
The pumps are suitable for universal use due to their variable differential pressure and flexible rotational speed. 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 achieve extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, which are inherently weak points if it involves stress surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a danger of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and screens the fuel temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower operating prices and considerably decreased maintenance costs. OktaLine Roots pumps can be operated with no bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that alternative on web site is fast and simple.
