Rotary vane pump RZ 2.5, two-stage

Rotary vane pump RZ 2.5

• The two-stage RZ 2.5 is a high-performance rotary vane pump with extra compact design and low weight.
• It is the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium gas flow rate.
• The rotary vane pumping unit PC 3 with cold trap (GKF 1000i) at the inlet helps the pump to handle larger volumes of condensable vapors.
• The pumping unit is compact, user-friendly, and well-arranged, with oil mist filter at the outlet, a valve, and a T-connection for a gauge.

Performance features:

• 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
