Periodic checking and replacement of vacuum pumping fluids is highly recommended, and some attention should be given to pump fluids when pump down times become excessively long. For replacement, a selection of commonly used oils is available. The choice of the appropriate oils and greases will depend on the types of pump and equipment in which they are used. The vapour pressure, viscosity, hydrocarbon content and compatibility with existing oils should all be taken into account before a selection is made.
