Roots pumps from Pfeiffer Vacuum’s OktaLine are good 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 pressure surge resistance of PN 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out as a result. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or warmth remedy.
As a results of the enlargement of the sequence, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the application, there is a selection between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible with out flame arresters. เกจแรงดันสูง means that, effectively, the complete pumping velocity of the pump is on the market.
The pumps are suitable for common use as a end result of their variable differential stress 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 extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak points if it involves strain 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 danger of zone entrainment. The built-in temperature sensor protects towards thermal overload and monitors the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % lower working costs and considerably decreased upkeep prices. OktaLine Roots pumps may also be operated without a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on site is quick and easy.
