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 protection requirements.
Zone entrainment of explosive gases is dominated out as a result. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or heat treatment.
As a results of the growth of the sequence, pumping speeds range from 280 to 8,a hundred m3/h. Depending on the appliance, there is a selection between gear class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. เครื่องมือใช้วัดความดัน implies that, effectively, the full pumping velocity of the pump is on the market.
The pumps are suitable for common use as a end result of their variable differential stress and versatile rotational pace. All pumps can be utilized at ambient temperatures ranging from -20 °C to + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extraordinarily low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity 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 isn’t any threat of zone entrainment. The integrated temperature sensor protects against thermal overload and displays the gas temperature in the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 % decrease operating prices and significantly decreased maintenance costs. OktaLine Roots pumps can additionally be operated with no bypass, since ATEX safety is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that substitute on website is fast and easy.
