Pfeiffer Vacuum expands the OktaLine ATEX collection

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 stress surge resistance of PN 16, they meet the very highest explosion protection necessities.
Zone entrainment of explosive gases is ruled out in consequence. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes corresponding to vacuum furnaces or heat therapy.
As a result of the expansion of the sequence, pumping speeds vary from 280 to 8,100 m3/h. Depending on the application, there is a alternative between gear class 2G or 3G. All pumps are suitable for temperature class T3. Forgotten is feasible without flame arresters. This means that, successfully, the total pumping speed of the pump is out there.
The pumps are suitable for common use because of their variable differential stress and versatile rotational speed. All pumps can be used at ambient temperatures starting from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, that are inherently weak points if it involves stress surges and are high-maintenance. Official are stress surge resistant as a lot as 1600 kPa. Due to their magnetic coupling, there is no threat of zone entrainment. The built-in temperature sensor protects towards thermal overload and displays the fuel temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as a lot as 20 percent decrease working costs and considerably decreased upkeep costs. OktaLine Roots pumps may additionally 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 website is fast and easy.
