Check oil level. Maintain the level between the two lines on the oil window during operation. Too high a level will cause excess oil mist.
Determine the vacuum level in your system with a thermocouple gauge or manometer. Be sure the pump is operating at a pressure of 10 Torr or lower for continuous operation.
A system leak(s) or degassing can cause excessive oil mist. Locate and seal the vacuum leaks. High vapor loads may require a larger pump to compensate. See Insufficient Vacuum section of this guide.
An oil eliminator can be installed for coalescing the oil mist from the exhaust gases. If an oil mist eliminator is already installed, the element may need to be replaced if saturated with oil. Open up oil mist eliminator and examine the element; replace if needed. Contact Us for correct mist eliminator parts.
Check the oil condition for any visible change in color or consistency. Contaminants in the oil can add to the amount of oil exhausted. Carry out a forced oil flush if contamination is discovered. Contact Us for forced oil flush instructions.
Check pump temperature. Normal operating temperature for a belt driven pump is approximately 130F degrees. Higher heat lessens viscosity of oil. Less viscous oil mists more than viscous oil.
