Vacuubrand High Vacuum Pumping
Units
HP 40B2 / HP 63B2
Application
|
Efficient, reliable and easy-to-operate vacuum devices are
essential for successful and time-saving work in laboratories. The
VACUUBRAND high vacuum pumping units HP 40B2 and HP 63B2 offer these
characteristics to meet customer requirements.
The complete high vacuum pumping units include:
 | an air cooled oil diffusion pump
| a two stage rotary pump RZ 2 (HP 40B2) resp. RZ 5 (HP 63B2) as
backing and roughing pump
| all internal pipes and valves, including high vacuum and
ventilation valve as well as by-pass line and valve. |
| |
The units are ready for operation, mounted in a portable pillar stand,
castor as accessories.
|
Advantages
The
high-vacuum pumping units HP 40B2 and HP 63B2 are particularly:
| Efficient
The backing pump always provides the necessary backing pressure
and the diffusion pump can thus attain its full pumping capacity
of 22 l/s (resp. 37 l/s) and its ultimate pressure in the 10-6
mbar range (with pump fluid DC 704).
| Rapid
The pumping units have a butterfly valve above the diffusion pump,
by-pass line and valve are therefore particularly efficient for
rapid evacuation cycles where the oil diffusion pump is always
maintained 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 in 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 (when gas ballast valve is closed).
| Handy and sturdy
Pump, valves and pipes are compactly mounted in a pillar stand.
Due to small overall dimensions and their light mass, the pumping
units can easily be transported to the systems to be evacuated,
and can be accommodated almost everywhere. In practice, the high
vacuum pumping units are often used as table top on laboratory
benches, because of their light weight and compactness.
| Economical
The high-vacuum pumping units HP 40B2 and HP 63B2 have an
electrical consumption of only 400 watts and need no water supply. |
