RZ 9Rotary vane pump
Overview
- very high flow rates even at vacuum levels approaching ultimate vacuum
- high water vapor tolerance due to efficient gas ballast; very good ultimate vacuum even with gas ballast
- vacuum-tight at switch-off; external anti-suckback valve not needed
- large oil volume: Long intervals between oil changes
- ease of maintenance due to telescopic design
Ultimate vacuum
2 x 10-3 mbar
Ultimate vacuum with gas ballast
1 x 10-2 mbar
Max. pumping speed 50 Hz
8.9 m3/h
Rotary vane pump in action
The RZ 9 is a two-stage powerful rotary vane pump for fast evacuation of vessels and at higher gas flow rates. Typical applications are lyophilization, fine vacuum distillation and drying chambers. The two-stage rotary vane pump RZ 9 is also available in various packages with matching accessories such as exhaust filter FO and valve VS 25. Rotary vane pumps are used for a process vacuum of a few mbar to 10-3 mbar.
