Vacuum oil VM-4 is an industrial lubricant and working fluid without additives for specialised equipment.
Vacuum oil application
In the industry
Vacuum oil VM-4 buy in Kharkov in the online shop of chemicals Novohim.
Vacuum oil by its composition refers to purified specialised oils used in forevacuum pumping equipment as well as in oil-sealed mechanical vacuum pumps. No additives. It has average kinematic viscosity at 50°C 48-57 mm²/s according to GOST.
Vacuum oil is used on high-performance vacuum-forming equipment. For example, it can be rotary, piston or liquid ring positive displacement pumps, etc.
Given the special operating conditions of pumping equipment where vacuum oil is used, there are a number of requirements to its characteristics, namely:
- composition stability
- narrow fractional composition
- low evaporation
- viscosity values
