Welch Premium pump oil comes in five different sizes:1 liter (800995-01)5 liter (800995-05)10 liter(800995-10)20 liter (800995-20)200 liter (800995-200)A triple distilled hydrocarbon oil using severely hydrotreated base stock is designed to resist breakdown at higher RPMs and operating temperatures of direct-drive vacuum pumps. The hydrotreating virtually eliminates aromatics and sulfur to give good resistance to sludge and varnish formation overtime in corrosive environments. Premium oil enables direct-drive vacuum pumps to maintain the highest vacuum performance over time. The oil is light yellow.
Pump oil can become contaminated with ingested fluids and vapors. Use recommended pump oil and change your pump oil regularly. Cloudy and discolored oil will lead to premature pump failure.

- Designated for high RPM direct-drive vacuum pumps
- No additives or inhibitors
- Recommended for Welch direct-drive vacuum pumps
- 800995-20 is the 20 liter size
Specially triple distilled mineral oil for the operation of CRVpro rotary vane pumps from Welch.
The oil fulfils the following functions in the vacuum pump:
- lubricating the sliding parts, such as rotor, vane, radial shaft seals
- sealing the moving parts against the stator wall to reduce leaks
- conducting the heat of compression to the metal walls (cooling)
The oil transports the polluted particles and corrosive media and thus effects continuous cleaning of the internal surfaces.
Please note that certain types of vacuum pump oils may not be used for certain applications. Please contact our sales team if you have questions.
