Pfeiffer Vacuum expands the OktaLine ATEX collection

Roots pumps from Pfeiffer Vacuum’s OktaLine are perfect 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 strain surge resistance of PN 16, they meet the very highest explosion safety requirements.
เกจวัดแรงดันลม of explosive gases is ruled out consequently. Potential functions vary from the chemical, biotechnology and pharmaceutical industries to industrial functions similar to vacuum furnaces or heat treatment.
As a result of the enlargement of the sequence, pumping speeds range from 280 to eight,a hundred m3/h. Depending on the appliance, there’s a alternative between equipment category 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible without flame arresters. This means that, successfully, the total pumping pace of the pump is out there.
The pumps are appropriate for common use because of their variable differential pressure and flexible 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 obtain extraordinarily low leak charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak factors if it comes to pressure surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as much as 1600 kPa. Due to their magnetic coupling, there is no risk of zone entrainment. The built-in temperature sensor protects in opposition to thermal overload and displays the fuel temperature within the outlet space.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves as much as 20 percent lower operating costs and significantly decreased maintenance costs. OktaLine Roots pumps can additionally be operated and not utilizing a bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on web site is quick and easy.
