ATEX certified magnetic coupled Roots pump suitable for medium and low vacuum applications
We have developed ATEX certified pumps based on the 2014/34/EU standard for the evacuation of explosive gases and the process flow in explosive environments to meet strict explosion-proof requirements.Maintenance of Okta 500 ATEX vacuum pump in Pfalz, Germany

The pumping speed range of Roots pump is 280 to 5190 m3/Within h. According to the different requirements of the application, you can choose device type 2 or type 3. All pumps are suitable for T3 temperature rating.

In Roots pumps, the gearbox and bearing belt are separated from the air pump chamber. Because the rotor operates under frictionless conditions, it ensures a dry operating environment.Maintenance of Okta 500 ATEX vacuum pump in Pfalz, Germany

Product advantages

• High explosion-proof safety performance - According to PN 16, explosion-proof safety is achieved through anti pressure surge technology
• No additional fire extinguishing device is required during installation
• The vacuum pump has good sealing performance (leakage rate less than 10%)-6Pa m3/s) - No inclusion of explosive gases
• High reliability - using an integrated temperature sensor to effectively prevent the pump body from overheating
• The vacuum pump can be operated directly (with ATEX protection when passive rotation is caused by the preceding vacuum airflow)
• On site maintenance is simple and easy to operate, and the engine is no exception (using standardized ATEX IEC engines that can be directly replaced on site)
• Due to different differential pressures and speeds (when using a frequency converter), the application has high flexibility

application

• heat treatment
• vacuum drying
• vacuum furnace
• biotechnology

This vacuum pump has another significant advantage, due to the use of convective cooling technology, the operating cost is significantly lower than that under water cooling conditions. Therefore, this vacuum pump can be widely applied in various fields. We have a very mature design concept in the design of Roots pumps, which has now developed into related designs involving magnetic coupling. Thanks to the excellent sealing performance of the vacuum pump, the product can achieve extremely low leakage rates.
