Roots pumps from Pfeiffer Vacuum’s OktaLine are ideal for use in processes in probably 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 16, they meet the very highest explosion protection requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial purposes similar to vacuum furnaces or heat treatment.
As a result of the growth of the series, pumping speeds vary from 280 to 8,one hundred m3/h. Depending on เกจวัดแรงดัน , there’s a choice between tools category 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible with out flame arresters. This signifies that, successfully, the total pumping speed of the pump is available.
The pumps are appropriate for common use as a end result of their variable differential strain and versatile 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 achieve extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak points if it involves strain surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant up to 1600 kPa. Due to their magnetic coupling, there is not a danger of zone entrainment. The integrated temperature sensor protects against thermal overload and screens the gas temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower working costs and considerably reduced upkeep costs. OktaLine Roots pumps can also be operated without a bypass, since ATEX protection is assured even with passive rotation (windmilling). The use of ATEX IEC motors signifies that substitute on site is quick and straightforward.
