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 stress surge resistance of PN 16, they meet the very highest explosion safety necessities.
Zone entrainment of explosive gases is dominated out in consequence. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial purposes corresponding to vacuum furnaces or heat remedy.
As a result of the enlargement of the series, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the applying, there’s a selection between gear class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible without flame arresters. diaphragm seal signifies that, successfully, the total pumping velocity of the pump is on the market.
The pumps are appropriate for universal use due to their variable differential strain and flexible rotational velocity. 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 extremely low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak points if it involves strain surges and are high-maintenance. OktaLine ATEX pumps are pressure surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t any risk of zone entrainment. The integrated temperature sensor protects in opposition to thermal overload and screens the fuel temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent decrease working costs and significantly lowered maintenance prices. OktaLine Roots pumps may also be operated without a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors means that replacement on website is quick and simple.
