Pfeiffer Vacuum expands the OktaLine ATEX collection

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 sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out as a result. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes corresponding to vacuum furnaces or heat therapy.
As a result of the enlargement of the series, pumping speeds vary from 280 to eight,a hundred m3/h. Depending on the applying, there is a selection between equipment category 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This means that, successfully, the complete pumping speed of the pump is on the market.
The pumps are appropriate for universal use because of their variable differential pressure and versatile rotational pace. pressure gauge แบบ น้ำมัน 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 obtain extraordinarily low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, which are inherently weak points if it comes to stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t any danger of zone entrainment. The integrated temperature sensor protects against thermal overload and monitors the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower operating prices and significantly decreased upkeep prices. OktaLine Roots pumps can also be operated and not utilizing a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that substitute on website is quick and simple.
