Vacuum Pump Oil
DirecTorr™ 20 Liter

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.
