Laboratory vacuum pump RZ 2.5

rotary vanelubricatedmulti-stage

Overview

• High pumping speed maintained even close to ultimate vacuum
• Good ultimate vacuum performance, including with gas ballast
• Vacuum‑tight on shutdown — no external anti‑suckback valve required
• Large oil capacity for extended oil change intervals
• Telescopic design for simplified maintenance

Product summary
The two‑stage RZ 2.5 is a compact, lightweight rotary vane pump designed for laboratory and process applications that require a low ultimate vacuum at medium gas throughput. The unit is available as a complete package including oil mist filter FO and isolation/butterfly valve VS 16, supplied ready for operation.
