Laboratory vacuum pump RZ 6

rotary vanelubricated

Overview

• High pumping speed even close to ultimate vacuum
• High water vapor tolerance with effective gas ballast; good ultimate vacuum with gas ballast
• Vacuum-tight on shutdown; no external anti-suckback valve required
• Large oil volume for longer intervals between oil changes
• Easy maintenance due to telescopic design

Product description
These two-stage rotary vane pumps combine compact dimensions and low weight with a pumping performance suitable for numerous laboratory and process applications requiring low ultimate vacuum at medium to elevated gas throughput. The RZ 6 is available as complete packages including oil mist filter FO, valve VS 16 and the VACUU·VIEW extended vacuum controller, delivered filled with oil and ready for use.
