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.
DIP
Oil Diffusion Pumps
DIP oil diffusion pumps are high vacuum pumps without any rotating parts.The pumping action of these fluid entrainment pumps in general is based on the transporting capacity of the vapour jet. Compared to other high vacuum pumps the pumping speed of diffusion pumps is extremely high with respect to the in-take area.The operating pressure range varies from 10-2 mbar and 10-7 mbar (0.75•10-2 torr and 0.75•10-7 torr). The pumping speed depending of the pump size from 3000 l/s bis hin zu 50000 l/s. The LEYBOJET pump is equipped with an additional ejector nozzle for obtaining a stable pumping speed into the medium vacuum range.
