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 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 functions range from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or heat therapy.
As a result of the enlargement of the collection, pumping speeds vary from 280 to eight,a hundred m3/h. Depending on เครื่องมือความดัน , there is a choice between equipment category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible without flame arresters. This implies that, effectively, the complete pumping velocity of the pump is available.
The pumps are appropriate for universal use as a outcome of their variable differential pressure and flexible rotational velocity. 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 extremely 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 involves pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a danger of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and displays the gasoline temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 % lower operating prices and significantly decreased upkeep prices. OktaLine Roots pumps can also be operated with no bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on site is quick and easy.
