Pfeiffer Vacuum expands the OktaLine ATEX sequence

Roots pumps from Pfeiffer Vacuum’s OktaLine are best 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 strain surge resistance of PN sixteen, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is ruled out in consequence. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial applications such as vacuum furnaces or heat remedy.
As a result of the enlargement of the series, pumping speeds vary from 280 to 8,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. diaphragm seal is possible without flame arresters. This implies that, effectively, the total pumping velocity of the pump is available.
The pumps are suitable for common use as a outcome of their variable differential pressure and flexible rotational velocity. All pumps can be utilized at ambient temperatures ranging from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extremely low leak charges of 10-6 Pa m3/s. diaphragm seal eliminates the need for shaft seals, which are inherently weak points if it comes to strain surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there isn’t a risk of zone entrainment. The built-in temperature sensor protects against thermal overload and monitors the gasoline temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease operating costs and considerably decreased maintenance prices. OktaLine Roots pumps can be operated with no bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that replacement on website is quick and simple.
