Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 strain surge resistance of PN 16, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out consequently. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial purposes similar to vacuum furnaces or heat remedy.
As a results of the expansion of the sequence, pumping speeds range from 280 to 8,100 m3/h. Depending on the application, there’s a selection between gear class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible with out flame arresters. This implies that, effectively, the total pumping pace of the pump is available.
pressure gauge trerice ราคา are suitable for universal use as a end result of their variable differential stress and flexible rotational velocity. 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 achieve extremely low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, that are inherently weak factors 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 no risk of zone entrainment. The built-in temperature sensor protects against thermal overload and monitors the gas temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower operating prices and considerably decreased maintenance prices. OktaLine Roots pumps may additionally be operated and not using a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors signifies that replacement on website is fast and easy.
