Product Description
The powerful two-stage RZ 9 rotary vane pumps are the ideal solution for a wide range of laboratory and process applications that require high pumping speed. It has best performance in laboratory applications. An excellent choice for freeze dryers up to 10 liters, centrifugal concentrators or other low-temperature evaporations of high boiling point solvents, molecular distillations, schlenk lines and other applications where diaphragm pumps cannot provide sufficient vacuum. Typical applications are lyophilization, fine vacuum distillation, drying chambers, fast evacuation of vessels, and the pumping of large amounts of vapor.
Performance Features:
- 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
