Roots pumps from Pfeiffer Vacuum’s OktaLine are good 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 necessities.
Zone entrainment of explosive gases is ruled out consequently. Potential purposes vary from the chemical, biotechnology and pharmaceutical industries to industrial applications similar to vacuum furnaces or warmth remedy.
As a results of the enlargement of the series, pumping speeds vary from 280 to 8,a hundred m3/h. Depending on the appliance, there’s a selection between tools class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is feasible with out flame arresters. This implies that, effectively, the total pumping velocity of the pump is on the market.
The pumps are appropriate for common use as a 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 charges of 10-6 Pa m3/s. The magnetic coupling eliminates the necessity for shaft seals, that are inherently weak points if it involves stress surges and are high-maintenance. OktaLine ATEX pumps are stress surge resistant as a lot as 1600 kPa. ราคาเพรสเชอร์เกจ to their magnetic coupling, there isn’t any risk of zone entrainment. The built-in temperature sensor protects against thermal overload and monitors the gas temperature within the outlet area.
Compared to pumps with shaft seals, the OktaLine’s magnetic coupling achieves up to 20 percent lower working costs and considerably decreased maintenance costs. OktaLine Roots pumps can be operated and not utilizing a bypass, since ATEX protection is guaranteed even with passive rotation (windmilling). The use of ATEX IEC motors implies that replacement on site is quick and simple.
