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 pressure surge resistance of PN sixteen, they meet the very highest explosion protection necessities.
Zone entrainment of explosive gases is ruled out consequently. Potential functions range from the chemical, biotechnology and pharmaceutical industries to industrial purposes such as vacuum furnaces or heat treatment.
As a result of the growth of the collection, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the application, there is a choice between gear class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This signifies that, effectively, the full pumping velocity of the pump is available.
The pumps are suitable for common use as a end result of their variable differential strain 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 obtain extraordinarily low leak charges 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 strain surge resistant as a lot as 1600 kPa. เกจวัดแรงดันลมดิจิตอล to their magnetic coupling, there is not any risk of zone entrainment. The built-in temperature sensor protects against thermal overload and screens the fuel temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent decrease operating costs and significantly lowered maintenance prices. OktaLine Roots pumps can be operated without a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that alternative on site is fast and straightforward.
