Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal 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 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is dominated out as a result. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or warmth treatment.
As a results of the growth of the sequence, pumping speeds range from 280 to eight,100 m3/h. Depending on เกจวัดความดันpressuregauge , there’s a selection between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This means that, effectively, the full pumping speed of the pump is available.
The pumps are suitable for universal use as a end result of their variable differential pressure and versatile rotational pace. 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 obtain extremely low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak factors 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 any threat of zone entrainment. The integrated temperature sensor protects towards thermal overload and monitors the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % lower operating prices and significantly reduced upkeep prices. OktaLine Roots pumps can also be operated with no bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors signifies that substitute on site is quick and straightforward.
