Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are good for use in processes in doubtlessly 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 in consequence. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or heat therapy.
As a results of the expansion of the series, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the applying, there is a choice between gear class 2G or 3G. All pumps are suitable for temperature class T3. Installation is possible without flame arresters. This means that, successfully, the total pumping velocity of the pump is on the market.
The pumps are appropriate for universal use as a outcome of their variable differential strain and versatile rotational velocity. All pumps can be used at ambient temperatures ranging from -20 °C to + 40 °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and achieve extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, that are inherently weak factors if it involves pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant up to 1600 kPa. Due to their magnetic coupling, there isn’t a risk of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and displays the gas temperature in the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent decrease working costs and considerably lowered upkeep costs. OktaLine Roots pumps can be operated and not utilizing a bypass, since ATEX protection is assured even with passive rotation (windmilling). ส่วนประกอบpressuregauge of ATEX IEC motors means that replacement on web site is quick and easy.
