Vacuum pumps for laboratories and production Busch Vacuum Pumps and Systems has now launched a new series of vacuum pumps for a wide range of applications. The new two-stage oil-lubricated rotary vane vacuum pumps Zebra RH were developed both for research laboratories and for production processes that work in the medium vacuum range. Robustness and reliability of operation are the outstanding qualities of Zebra RH rotary vane vacuum pumps. The proven rotary vane vacuum technology from Busch has long established itself as the industry standard in the rough vacuum range. With the new series, Busch is now making inroads in the medium vacuum range. All Zebra RH sizes achieve ultimate pressures <0.0076 hPa (mbar). The series includes eight sizes and covers pumping speeds from 2.4 to 90 m3/h. Zebra RH vacuum pumps are thus also highly suitable as backing pumps for turbomolecular vacuum pumps and can be used in this combination in the high vacuum range. The consistently high vacuum level in continuous operation

robust principle, modern design Dolphin LT is the new generation of liquid ring vacuum pumps from Busch, with all the advantages of proven technology plus additional refinements. Dolphin LTs are two-stage vacuum pumps and operate from atmospheric pressure to 33 hPa (mbar). The Dolphin LT series is available in a total of eight sizes, allowing an exact match to every process. The operating fluid is usually water, but other liquids may be used if required by the process conditions. Dolphin LT liquid ring vacuum pumps may be operated as a simple continuous flow system, or as a partial or total recirculation system. The precisely dimensioned range of sizes, extensive range of accessories and choice of construction materials allow these vacuum pumps to be perfectly adapted to many different industrial processes. Dolphin LT technology uses the proven liquid ring principle, with contact-free internal components and virtually isothermal compression. The LT series has been developed for continuous

New Vacuum Pump Generation with Improved Energy Efficiency Busch Vacuum Pumps and Systems is presenting its new series of rotary vane vacuum pumps designed specifically for packaging machines, offering energy savings of 20%. The new RD series is based on the proven technology of R 5 rotary vane vacuum pumps, which have been the industry standard for decades in food production and packaging. Technical optimization of individual components has allowed energy consumption to be reduced significantly without affecting reliability and robustness. At the same time, the pumping speed of individual models at high vacuum levels has also been increased, which for meat product packagers means reduced cycle times and lower energy consumption. All components requiring maintenance are mounted on one side of the unit for easier access, thereby reducing downtime. The cooling air circulation has also been optimized. The exhaust air outlet may be directed sideways or downward, depending on how the RD is built into the packaging machine. A gas

the economical solution for vacuum and overpressure applications. Samos side channel blowers may be used in all areas where pulsation-free vacuum and pressure services are required. Units may be installed horizontally or vertically. The die-cast aluminium construction makes this a very robust product. Maintenance-free Sealed-for-life bearings, a fan-cooled drive and a non-contact impeller all ensure that the Samos side channel blower is maintenance-free. Environmentally safe Samos side channel blowers are exceptionally environment-friendly, as they require no operating fluids. An internal silencer allows the Samos to run very quietly, whilst the drive has energy-efficient motors.

efficient and reliable vacuum and compressed air generation Mink claw vacuum pumps have been developed specifically for industrial applications in which constant vacuum, high pumping speed and completely oil-free compression are essential. Mink claw vacuum pumps operate contact-free; neither oil nor operating fluids are required during compression. The sophisticated claw technology of Mink claw vacuum pumps permits extremely high efficiency levels to be achieved, reducing energy consumption and increasing performance. These vacuum pumps operate contact-free and require almost no maintenance. In practice, this means 60% lower energy and operating costs compared to conventional vacuum generators. The same claw technology is also used for Mink compressors. They provide oil-free overpressure at up to 2 bar (g) and volume flows of up to 580 m3/h.
