Secondary vacuum pumps, such as diffusion or turbo-molecular pumps, enable final vacuums from 10-3 up to 10-9 mbar. Even vacuums up to 10-12 mbar can be generated in the ultra-vacuum area. At such low, atmospheric vacuums, lubricants are subject to high chemical and oxidative impacts and must meet particular selection criteria. The viscosity grades of LUBCON vacuum oils are tailored to the internal secondary vacuum pump temperatures. The synthetic oils offer very low saturation pressure and therefore achieve the desired final vacuums. In the high and ultra-high vacuum sector, LUBCON vacuum pump greases assure the optimum and long-lasting operation of pumps in diverse applications. They are resistant towards nuclear radiation, oxidation, high temperatures and can be utilised for the evacuation of all
