What Vacuum Pump Oil Should I Use for a Two-Stage Rotary Vane Vacuum Pump?

Posted by VACOIL on 1st Mar 2022

Finding the right vacuum pump oil for your pump can be challenging. Below we have highlighted our three vacuum pump oils designed for two-stage rotary vane vacuum pumps. If you have any questions give us a call at 801-486-1015.

If your vacuum pump is always getting contaminated, requiring you to change the oil often, 19 Grade is the best option for you. This oil is the lower-priced option but still has a premium performance. This is a higher viscosity, designed for direct-drive rotary vane vacuum pumps, and ideal for most general purpose applications. The low vapor pressure reduces system backstreaming and thermal stability provides resistance to oxidation and sludge formation.

20 Grade is an upgraded oil from the 19 Grade. It is a severely hydro-treated paraffinic oil that is double distilled through a molecular distillation process to remove light end fractions. 20 Grade is highly saturated and contains less than 0.01% sulfur similar to technical white oils. Its high molecular weight and viscosity index provides longer service life and reduced build-up of varnish and carbonized oil on the internal pump components.

If you want your oil to last a long time so you don't have to spend time changing it, Elite Z is the option for you. This oil is double distilled to exhibit the highest performance for mechanical pumps. EZ Grade is a full synthetic hydrocarbon vacuum fluid that is very resistant to thermal and chemical attacks and provides longer oil life and superior protection to the vacuum pump.
