Pfeiffer Vacuum expands the OktaLine ATEX sequence

Roots pumps from Pfeiffer Vacuum’s OktaLine are excellent 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 16, they meet the very highest explosion safety requirements.
เกจ์วัดแรงดันน้ำมันเครื่อง of explosive gases is dominated out in consequence. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial applications corresponding to vacuum furnaces or heat treatment.
As a results of the enlargement of the sequence, pumping speeds range from 280 to eight,100 m3/h. Depending on the applying, there’s a alternative between equipment class 2G or 3G. All pumps are suitable for temperature class T3. Installation is feasible with out flame arresters. This means that, effectively, the full pumping velocity of the pump is on the market.
The pumps are appropriate for universal 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 + forty °C.
In view of their magnetic coupling, OktaLine pumps are hermetically sealed and obtain extraordinarily low leak rates of 10-6 Pa m3/s. The magnetic coupling eliminates the need for shaft seals, which are inherently weak factors if it involves pressure surges and are high-maintenance. OktaLine ATEX pumps are strain surge resistant as much as 1600 kPa. Due to their magnetic coupling, there is not any risk of zone entrainment. The integrated temperature sensor protects towards thermal overload and screens the gas 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 reduced maintenance costs. OktaLine Roots pumps may additionally be operated and not utilizing a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors signifies that replacement on site is fast and easy.
