High-quality vacuum oil VM-3, used as a working fluid in high-performance steam-oil booster pumps in various auxiliary steam-jet and special forevacuum pumps. VM-3 oil has a low viscosity and high thermo-oxidative stability in conditions of high pumping speed.
Application area
It is used as a working fluid in high-performance steam-oil booster pumps in various technological processes of instrumentation and apparatus engineering, in high-quality metallurgy, petrochemistry, electronics, mass spectrometry, accelerator technology, etc.
Benefits
- Improves sealing of working chambers;
- Reduces friction power loss;
- Optimum viscosity for each specific case;
- Sufficiently low saturated vapor pressure (oil evaporation and the degree of vacuum achieved depend on it);
- Environmental Safety;
- High hydrolytic stability during evacuation of vapors and air;
- Low gas solubility.
