Higher performance with a pumping speed up to 8,100m³/h Can be used individually for ambient temperatures from -20  to +40  °C °C Protection against thermal overload thanks to integrated temperature sensor Easy installation and maintenance Technically dry operation The gear and bearing housings are separated from the pumping chamber by labyrinth seals. Contact-free rotation of the Roots ensures technically dry operation. Flexible in application Thanks to the variable differential pressure and flexible rotation speed, the pumps can be used universally. All pumps can be used in ambient...

OktaLine® ATEX ATEX regulations Certification for ATEX The word ATEX is an acronym from French and stands for ATmosphères EXplosibles. Vacuum pumps for use in a potentially explosive atmosphere must be certified in accordance with 2014/34/EU. To do this, the measures shown in Figure 1 must be carried out. The first step is the analysis of potential ignition sources. Depending on the category in the CE marking, the status regular operation (category 3), expected failure (category 2) and rare failure (category 1) are considered with regard to potential ignition sources. The next step is to...
