Vacuum oil VM-1 (5l.)
vacuum oil
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.
