High-Vacuum Pumping Units HP 40 B2 and HP 63 B2

Application

High-performance, reliable and easy-to-operate vacuum equipment is essential for successful and time-saving work in laboratories. The VACUUBRAND High-Vacuum Pumping Units HP 40 B2 and HP 63 B2 have these characteristics and fulfill practical requirements.

Components of high-vacuum pumping units HP 40 B2 and HP 63 B2:

• Air-cooled oil diffusion pump
• Two-stage rotary-vane pump: RZ 2.5 (for HP 40 B2) or RZ 6 (for HP 63 B2) as backing pump
• Connection tubings and valves, including high-vacuum and ventilation valves and by-pass line

All components are mounted on a portable stand and the pumping unit is ready to use.

Advantages

The pumping units HP 40 B2 and HP 63 B2 are especially:

• efficient
  The backing pump generates the necessary backing pressure so that the diffusion pump can always attain its full pumping capacity of 22 l/s (37 l/s resp.) and ultimate vacuum of approx. 10^—6 mbar (with pump fluid DC 704 and cold trap).
• rapid
  The pumping units have a high-vacuum butterfly valve between diffusion pump and recipient and a by-pass line. The valves are lever-operated, clearly indicating open/closed position. The by-pass line makes them particularly fit for rapid evacuation-cycles where the oil diffusion pump stays heated and ready for operation.
• functional and easy to operate
  Smaller experimental set-ups can be mounted directly on the high-vacuum pumping units. Switches for backing and diffusion pump are centrally grouped on a panel. A short operation diagram makes the units easy to use. All valves and switches are operated from the front. The pumping units are vacuum-tight after switching off (with gas ballast valve closed).
• compact and sturdy
  Pumps, valves and tubing are compactly mounted on a pillar stand. Due to its small overall dimensions, light weight and air cooling, the pumping unit can be easily transported to the systems to be evacuated, and can be accommodated almost everywhere. Due to their air-cooled space-saving design, the high-vacuum pumping units are often used as table-top on laboratory benches.
• economical
  The High-Vacuum Pumping Units HP 40 B2 and HP 63 B2 have a power consumption of only 0.4 kW and 0.54 kW and do not require any water supply. They are very economical compared to wide-range turbo-molecular pumps, since there is no expensive regular maintenance (e.g. replacement of rotor bearings).
