A new magnetically coupled rotary vane pump

The Duo 11 ATEX rotary vane pump (photo), which meets ATEX directive 2014/34/EU, was introduced for processes taking place in potentially explosive atmospheres or conveying explosive gases and vapors. As such, it satisfies the most stringent explosion-protection requirements. The ATEX certification applies for both the interior and exterior of the pump. The Duo 11 ATEX is classified as equipment category 3G and temperature class T4. It can convey all gases up to and including explosion group IIC. The pumping speed is 9 m3/h at 50 Hz and 10.5 m3/h at 60 Hz. The Duo 11 ATEX is equipped with a frictionless magnetic coupling. As a result, the shaft seal rings that are used with other rotary vane pumps can be dispensed with. The extra safety that the magnetic coupling provides is important in explosive atmospheres: without shaft seal rings, it is impossible for media inside the pump to escape out through faulty shaft-seal rings. — Pfeiffer Vacuum GmbH, Asslar, Germany
