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 pressure surge resistance of PN sixteen, they meet the very highest explosion safety requirements.
Zone entrainment of explosive gases is ruled out consequently. Potential purposes range from the chemical, biotechnology and pharmaceutical industries to industrial functions corresponding to vacuum furnaces or heat remedy.
As a result of the enlargement of the series, pumping speeds vary from 280 to 8,one hundred m3/h. Depending on the applying, there is a alternative between equipment class 2G or 3G. All pumps are appropriate for temperature class T3. Installation is possible without flame arresters. pressure gauge digital ราคา means that, successfully, the complete pumping speed of the pump is available.
The pumps are appropriate for common use due to their variable differential pressure and versatile rotational velocity. All pumps can be utilized 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 need for shaft seals, that are inherently weak factors if it comes to 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 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 % lower working costs and considerably decreased maintenance prices. OktaLine Roots pumps can additionally be operated without a bypass, since ATEX safety is assured even with passive rotation (windmilling). The use of ATEX IEC motors means that alternative on site is quick and easy.
