Laboratory vacuum pump RZ 9

rotary vanelubricatedmulti-stage

Overview
RZ 9 is a two-stage rotary vane pump designed for rapid evacuation of vessels and for applications requiring high gas throughput. The pump is supplied ready for use, filled with pump oil and accompanied by a manual.

Key features

• Very high pumping speed even at pressures approaching the ultimate vacuum
• High water vapor tolerance thanks to an effective gas ballast; very good ultimate vacuum even with gas ballast open
• Vacuum-tight at switch-off; external anti-suckback valve not required
• Large oil capacity enabling extended intervals between oil changes
• Easy maintenance due to telescopic design
