Roots pumps from Pfeiffer Vacuum’s OktaLine are good 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 stress surge resistance of PN 16, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is dominated out consequently. ร้านซ่อมเครื่องวัดความดันโลหิต from the chemical, biotechnology and pharmaceutical industries to industrial functions corresponding to vacuum furnaces or heat therapy.
As a result of the enlargement of the sequence, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the appliance, there is a selection between equipment category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible without flame arresters. This means that, successfully, the total pumping velocity of the pump is available.
The pumps are appropriate for common use as a result of their variable differential pressure and versatile rotational pace. All pumps can be used at ambient temperatures starting 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 factors if it comes to strain 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 not a threat of zone entrainment. The integrated temperature sensor protects in opposition to thermal overload and screens the gasoline temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent decrease operating prices and significantly reduced maintenance prices. OktaLine Roots pumps may additionally be operated and not using a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors means that substitute on site is fast and straightforward.
