Vacuum oil VM-1 (5l.)

vacuum oil

SKU: 683057779 Category:

Description

VM-1 Vacuum TU 38.401-58-3-90 oil is used as working fluid in the fore-vacuum reciprocating and rotary vane pumps. Vacuum VM-1 oil due to the high degree of vacuum cleaning oil bases, different narrow fractional composition, low volatility and high stability against oxidation.

Applications

VM-1 Vacuum oil is used in reciprocating high performance vacuum pumps AVZ, NWS. Permissible use of mechanical vacuum pumps with 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 evacuated vapor and air;



  • Small gazorastvorimost.
