Oil for vacuum pumps
vacuum oil
Description
Vacuum oil is designed for use in rotary and vane vacuum pumps. Vacuum oil allows to obtain at low vacuum pressures. Suitable for use in most industrial rotary vacuum pumps. Vacuum oil is based on a carefully purified mineral base oils with good natural resistance to oxidation and decomposition. Due to this butter is characterized by long service life and low tendency to form sludge and deposits. Narrow Fractional vacuum oil composition provides a very low vapor pressure. This allows the pump to easily reach the vacuum for which it was designed. It also helps prevent oil thickening due to evaporation of the light fractions.
