Description The one-stage RE 2.5 and two-stage RZ 2.5 are high-performance rotary vane pumps with extra compact design and low weight. They are 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. The RZ 2.5 is also available combined with the oil mist filter (FO) and the VS 16 valve as a package. 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 Technical data Number of stages2 Max. pumping speed at 50/60 Hz m3/h 2.3 / 2.8 Max. pumping speed at 50/60 Hz cfm 1.4 / 1.6 Ultimate partial vacuum (abs.) mbar 4 x 10-4 Ultimate vacuum (abs.) mbar/torr 2 x 10-3 / 1.5 x 10-3 Ultim. vac.
