Description
Vacuum oil VM-1c is used as a working fluid in a steam-high vacuum pumps, mechanical vacuum pump with an oil seal. The most important parameters for the operation of VM-1c are vacuum oil viscosity, the boiling point at a residual pressure of 0.01 Torr, vapor pressure at 20 ° C.
Applications
Vacuum oil VM-1C is used as a working fluid in a steam-high vacuum pumps, mechanical vacuum pump with an oil seal.
Benefits
- 
It improves the sealing of the working chambers; 
 - Reduces power losses due to friction; 
 - The optimum viscosity for each case; 
 - sufficiently low vapor pressure (it depends on the volatility of oil and achievable degree of vacuum); 
 - Environmental security; 
 - High hydrolytic stability upon evacuation of vapors and air; 
 - Small gazorastvorimost.
