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 stress 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 applications vary from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or heat treatment.
As a result of the growth of the collection, pumping speeds vary from 280 to eight,100 m3/h. Depending on the application, there is a choice between gear category 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This means that, effectively, the total pumping velocity of the pump is on the market.
The pumps are suitable for universal use due to their variable differential stress and versatile 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 extraordinarily low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak factors if it comes to stress surges and are high-maintenance. pressure gauge are pressure surge resistant as much as 1600 kPa. Due to their magnetic coupling, there isn’t a threat of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and displays the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 % decrease operating prices and considerably decreased upkeep costs. OktaLine Roots pumps can be operated without a bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that substitute on web site is quick and simple.
