Pfeiffer Vacuum expands the OktaLine ATEX collection

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 stress surge resistance of PN sixteen, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is dominated out in consequence. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or warmth therapy.
As a result of the growth of the sequence, pumping speeds vary from 280 to 8,one hundred m3/h. Depending on the appliance, there’s a choice between equipment class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible with out flame arresters. This implies that, successfully, the complete pumping pace of the pump is available.
เกจวัดco2 are suitable for universal use because of their variable differential pressure and versatile rotational velocity. All pumps can be utilized at ambient temperatures starting 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 need for shaft seals, which are inherently weak factors if it comes to strain surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The built-in temperature sensor protects towards thermal overload and screens the fuel temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent decrease working prices and considerably reduced upkeep costs. OktaLine Roots pumps can additionally be operated without a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that alternative on site is quick and straightforward.
