Vacuum oil VM-6 is used as a working fluid in fore-vacuum piston and rotary vane pumps. VM-6 oil is a well-refined mineral oil that is produced from low-sulfur non-paraffin oils by deep refining of their narrow fractions and using an additional 1-2 stages of fine vacuum distillation.
Application area
Vacuum oil VM-6 is used in high-performance piston vacuum pumps AVZ, NVZ. Permissible use 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.
