Vacuum oil BM-11 is a working fluid in steam-jet vacuum auxiliary pumps. BM-11 oil is characterized by stable oxidation stability, which ensures the duration and reliability of operation of steam-jet pumps; long life of oil in the pump without replacement.
Application area
The main field of application of vacuum oils is volumetric vacuum pumps (high-vacuum steam-oil, mechanical with oil seal, steam-oil booster, steam-jet, and also for filling liquid vacuum gauges).
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.
