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 stress surge resistance of PN sixteen, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is ruled out as a result. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or heat remedy.
As a results of the expansion of the series, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the application, there’s a choice between gear category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. diaphragm seal implies that, successfully, the complete pumping speed of the pump is out there.
The pumps are appropriate for common use because of their variable differential stress and versatile rotational speed. 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. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak points if it involves stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there is no threat of zone entrainment. The built-in temperature sensor protects against thermal overload and monitors the fuel temperature in the outlet space.
Compared to pressure gauge octa with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease working costs and significantly decreased maintenance costs. OktaLine Roots pumps can be operated and not using a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that substitute on site is quick and simple.
