VACUUBRAND rotary vane pumps are high-performance, yet compact, and can be equipped with an extensive line of VACUUBRAND accessories. They have an innovative lubrication system with a built-in oil pump, and have a large oil volume. This extends oil change and service intervals, and protects the pump at start-up. The effective gas ballast feature, with its high-flow gas ballast, supplies high vapor compatibility for water and solvents. VACUUBRAND rotary vane pumps’ volume flow rate is specified at atmospheric pressure, as is customary with PNEUROP®. For process effiency, however, the high volume flow rate of VACUUBRAND pumps under process conditions, as well as a consistently high volume flow rate over a wide pressure range, is the key to your satisfaction in real-world application. After switch-off the aggregate is vacuum-sealed to protect your application from undesired venting and oil back flow. • constriction-free vapor pathway allows high volume flow rates, even when close to the ultimate vacuum • high tolerance for water and solvent vapors, because of the high-volume gas ballast • quiet running and excellent ultimate vacuum, even with gas ballast • active corrosion protection: Oil cycle closes vacuum-tight against the intake of corrosive gases and oil impurities into the reservoir when shut down • new design lubrication circuit, and large usable oil volume provides extended oil change and service intervals • compact design, low weight and easy service with telescopic design Items supplied: Pump oil filled and completely mounted, ready for use, with manual.

They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium gas flow rate. 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 Type Pumping speed m3/h Ultimate vacuum mbar Weight kg L × W × H mm Order No. 5RE 2.5 2.3 3×10-1 10.2 316 × 125 × 190 10 18 77150 5 Accessories Packages fine vacuum control The packages enable convenient vacuum control in the fine vacuum range down to 10-3 mbar and consist of a VACUU·SELECT vacuum controller, a VACUU·VIEW extended fine vacuum gauge, a VV-B 15C in-line solenoid valve and all necessary small flange components. Separator inlet side AK R 2.5/6 Separators at the inlet protect pumps from particulates and droplets which may shorten service intervals and even reduce the lifetime and the operating performance of oil-sealed rotary vane pumps. Oil mist filter outlet side FO R 2/2.5/5/6 Exhaust gases from oil-sealed rotary vane pumps always carry a certain quantity of oil mist. This is extremely unpleasant, and even harmful, for those working nearby. VACUUBRAND oil mist filters separate nearly 100% of oil mist at the ultimate vacuum of the pump.
