High Vacuum Pumps
Leybold offers a broad range of different high and ultra high vacuum pumps. These pumps vary in the principle of operation and field of application: turbomolecular vacuum pumps of the TURBOVAC and MAG series, diffusion vacuum pumps DIP and cryo vacuum pumps of the COOLVAC series. Important items for the selection of the adequate high vacuum pump are: attainable ultimate pressure, required pumping speed, gas throughput or compression.

Cryo Pumps, Cold Heads, Compressors
COOLVAC vacuum pumps are gas entrapment cryo pumps where gaseous substances are bound to the cold surfaces within the pump by means of cryocondensation, cryosorption or cryotrapping. For that purpose the cold surfaces (cryopanels) must be cooled to a sufficiently low temperature. The COOLVAC pumps are cooled by two-stage cold heads of the COOLPOWER series using the Gifford/McMahon principle. COOLVAC pumps produce a hydro carbon free ultra high vacuum in the pressure range from 10-3 mbar to 10-11 mbar (0.75•10-3 to 0.75•10-11 Torr).
COOLPOWER Cold Heads
Refrigerator cold heads of the COOLPOWER series are gas cooling machines which operate on the basis of a thermodynamic cycle to produce cryogenic temperatures. The COOLPOWER cold heads are the basic units for cryo vacuum pumps of the COOLVAC series and refrigeration cryostats RDK.
