Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal for use in processes in probably 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 requirements.
Zone entrainment of explosive gases is ruled out as a result. Potential applications range from the chemical, biotechnology and pharmaceutical industries to industrial purposes such as vacuum furnaces or warmth remedy.
As a result of the enlargement of the sequence, pumping speeds range from 280 to eight,a hundred m3/h. Depending on the applying, there’s a selection between tools class 2G or 3G. All pumps are suitable for temperature class T3. เกจวัดแรงดันลม is possible with out flame arresters. This signifies that, successfully, the total pumping velocity of the pump is on the market.
The pumps are appropriate for common use due to their variable differential pressure and flexible rotational speed. All pumps can be used at ambient temperatures ranging 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 need for shaft seals, that are inherently weak factors if it involves stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a risk of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and displays the fuel temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent lower operating costs and significantly reduced maintenance prices. OktaLine Roots pumps can be operated without a bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors signifies that substitute on web site is fast and straightforward.
