The lowest temperature at which the oil still flows is called the pour point. If the temperature drops below the permissible limit, the oil begins to solidify and loses its fluidity. In cold climate regions, the oil must have a low pour point. The lowest temperature at which the oil ignites when exposed to a flame source is called the flash point. The higher the flash point, the lower the fire hazard. Viscosity refers to the thickness of the oil; in other words, the fluid’s resistance to flow. Temperature, pressure, base oil type, and additives affect viscosity. For example, as temperature increases, viscosity decreases and the oil becomes thinner. Density refers to the weight or mass of the oil. For example, how heavy one liter of oil is.

Molish Vacuum Oil

Roles of Oil in Vacuum Pumps Oil in vacuum pumps is used as a lubricant to reduce friction and wear of moving parts, and also for sealing and protecting the pump against moisture and other contaminants. The presence of oil also helps transfer heat from the pump, maintain vacuum, and prevent air leakage into the system. The type of oil used in a vacuum pump depends on the pump type and its application, but typically mineral oils and synthetic oils are used. Oil plays various roles in vacuum pumps, including: Acting as a filler for empty spaces and sealing system (to prevent air from entering the clearance between pump parts and to enable proper vacuum generation). Oil can be effective in creating suction close to absolute zero, since the vapor pressure of oil is much higher than that of water (provided that standard vacuum pump oil is used). It serves as a lubricant and prevents wear of different components (Molish oil has very high viscosity and adhesiveness, which completely coats the surface of the rotor and vanes in the vacuum pump and protects them from environmental factors).
