Name: Rotary vane pump RZ 9 Series
SKU: RZ 9

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

The RZ 9 is a two-stage powerful rotary vane pump for fast evacuation of vessels and at higher gas flow rates.
