Vacuum oil BM-1с (TU 38.1011187-88) is produced from sulfur or low-sulfur paraffin oils by deep refining and special multi-stage fine vacuum distillation. It has high hydrolytic and antioxidant stability.
Application area
Vacuum oil VM-1C is used as a working fluid in high-vacuum steam-oil pumps, in mechanical vacuum pumps with oil seal.
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.
