First of all, Understand – Not All Vacuum Pump Oils Are The Same
There are three types of vacuum pump oils-
1. Mineral Vacuum Pump oil – traditional oils made by refining crude oil – still being used by those who haven’t woken up to the countless benefits that synthetic oils offer.
2. Semi-Synthetic Vacuum Pump Oil– Also known as ‘blends’- made by mixing mineral and synthetic oils – not recommended for vacuum pumps.
3. Synthetic Vacuum Pump oil – made by advanced refining process of the base oil in which individual molecules of the oil are customized to the extreme demands of the vacuum pump.
Secret # 1 –
1) Mineral oil tends to turn viscous (thick) at low temperatures, taking time to circulate within the pump. This causes friction, and therefore, wear within the vacuum pump.
Once the vacuum pump runs for a few hours, the oil inside tends to heat up. Mineral oils under such conditions tend to go thin and runny giving no lubrication to the pump parts.
SV-77 molecules, on the other hand, have been engineered for high-temperature stability. So it retains its viscosity and lubricity even in very hot conditions. Furthermore, it is designed to protect the vacuum pump from deposits and prolongs the vacuum pump life.
