VARIO Chemistry Pumping Units combine the latest control circuitry and software with state-of-the-art mechanics. They can achieve an ultimate vacuum down to 0.6 mbar and provide all the advantages of dedicated chemistry diaphragm pumps. VARIO Chemistry Pumping Units are quiet in operation. They generate a 100% oil-free vacuum. Gases and vapours only come in contact with plastics of optimum chemical resistance.

Traditional two-point control Continuously variable control by intelligent software Convenient, efficient and safe with optimum solvent recovery

THE COMPAny: With 150 employees and over 40 years of experience, VACUUbRAnD manufactures the most compre-hensive range of laboratory and instrumentation vacuum pumps, gauges and controllers for rough and fine vacuum.

The product range comprises rotary-vane pumps, oil-free diaphragm pumps, complete pumping units, flexible vacuum systems and solutions for local area networks. The range is completed by a wide choice of fittings and accessories as well as vacuum gauges and controllers for rough and fine vacuum.

Our technical literature is only intended to inform our customers. The validity of general empirical values and results obtained under test conditions for specific applications depends upon a number of factors beyond our control. It is, therefore, strictly the users’ responsibility to verify carefully the validity or suitability to their specific requirements. no claims arising from the information provided in this catalogue will consequently be entertained. Technical data are subject to change without notice.

Perfect control over your processThe VACUU·bUS Control bus provides the internal communication between the nT VARIO Diaphragm Pump and the CVC 3000 Vacuum Controller. In combination with a range of accessories, this new control bus facilitates the user-friendly design even of complex vacuum installations.

• Space-saving and flexible: the pumping unit with the controller can be located at distances up to 30 m away from the vacuum system

• Vacuum measurement and venting directly at the system through remote sensors and valves• Few connectors, many components: uniform plug connectors and automatic component

recognition• Cabling to resist dusty or wet environments: plug connectors have protection rating IP67• Reproducible cycles and routines: even complex processes can easily be saved, edited and repeated• no condensate overflow: liquid level detection sensor for exhaust condenser reservoir available
