What does vacuum pump oil do?
The primary role of most oils is mechanical lubrication, and the vacuum pump is no different. Additionally, the vacuum pump oil seals the vanes in rotary vane pumps, cooling the pump through heat transfer between the inner and outer parts of the pump.
The oil does the following:
– Provides a seal across the vanes and duo seal between the high pressure and low-pressure side of the pump in two-stage pumps.
– Cools the pump by conducting heat from the stator to the outer casing, where it can be dissipated.
– Protects the metal parts from corrosion caused by oxygen and vapor from the system.
– Most importantly, it lubricates the moving parts of the pump.
Vacuum pump oil is a substance inside the pump that lubricates the pumping apparatus while also collecting moisture and contaminants from evacuated systems. Simply put, it’s what keeps the pump pumping. That is why changing oil as soon as it needs to be changed is critical.
Depending on your oil type, application, and possible contaminants, the frequency of oil changes can range anywhere from daily to monthly but more often will extend pump life.
As soon as there is a notable difference from its original clear state is a good time to change your oil. The signs above of contaminated vacuum pump oil help you determine whether your vacuum pump oil has altered its ability to keep its designed viscosity or its vapor pressure for maximum efficiency.
Change pump oil based on the manufacturer-approved method but generally when the oil is warm. Make sure to dispose of the oil in a legal and approved location.
