Pfeiffer Vacuum expands the OktaLine ATEX series

Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent 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 safety necessities.
Zone entrainment of explosive gases is dominated out as a result. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial functions such as vacuum furnaces or heat therapy.
As a results of the enlargement of the series, pumping speeds range from 280 to eight,a hundred m3/h. Depending on the appliance, there is a alternative between gear class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible with out flame arresters. This signifies that, successfully, the complete pumping speed of the pump is available.
The pumps are appropriate for universal use due to their variable differential stress and versatile rotational velocity. 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 obtain extraordinarily low leak charges of 10-6 Pa m3/s. เกจแรงดันสูง 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 as a lot as 1600 kPa. Due to their magnetic coupling, there is not any danger of zone entrainment. ความหมายของเครื่องวัดความดัน built-in temperature sensor protects against thermal overload and monitors the gas temperature within 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 significantly decreased upkeep prices. OktaLine Roots pumps can be operated with no bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that substitute on site is quick and simple.
