All these systems are usually dirty applications, vacuum furnaces, mass spectrometers, optical coating etc. All these applications depend on the same thing to ensure fast, clean pumping, and clean and correct silicon oil levels.
Over a period of about a year, the operation of the system and the gases pumped slowly contaminates the oil causing the pumping speed to drop and generate more back steaming of the silicon oil reducing the oil level.
Carbon deposits build up and the vapour pressure of the oil declines. Ensure that the pump is inspected and cleaned at least once every 12 months to ensure fast pump speeds and a longer pump life, resulting in greater production over the life of the pump.
AVT offers on-site servicing of vapour diffusion pumps or supplies all grades of silicon oil if you wish to service it yourself.
