Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 sixteen, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential applications vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes corresponding to vacuum furnaces or warmth remedy.
As a results of the enlargement of the series, pumping speeds vary from 280 to eight,one hundred m3/h. Depending on the appliance, there’s a choice between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This signifies that, successfully, the complete pumping pace of the pump is out there.
The pumps are suitable for universal use due to their variable differential pressure and versatile rotational speed. All pumps can be used at ambient temperatures ranging from -20 °C to + forty °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 comes to pressure 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 risk of zone entrainment. The built-in temperature sensor protects against thermal overload and displays the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % lower working costs and significantly reduced upkeep prices. เกจวัดแรงดัน4นิ้วราคา can additionally be operated with no bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on site is fast and easy.
