To ensure efficient operation and proper maintenance of any rotary vane pumps, and to minimize noise and oil vapors, it is important to use the correct type and quantity of oil. The Directorr™ Premium vacuum oil has been especially developed to have the proper viscosity, low vapor pressure, and chemical stability needed to produce peak pumping efficiency. It is a triple-distilled hydrocarbon oil for use in CRVpro pumps.
The oil fulfils the following functions:
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)
