Uleiuri minerale Shell Corena V 100

Shell Corena Oil V
Premium Vacuum pump lubricant

Shell Corena Oil V is a formulated from selected, premium performance, highly refined mineral oils without containing any additives. It has natural resistance against ageing. Corena V is suitable for the lubrication of rotary vacuum pumps.
Applications
Rotary vacuum pump
Corena V is designed for the use in rotary and slide van vacuum pumps. Here it can be used to a vacuum pressure of 1x10-3 mbar. This will cover most of the industrial and also laboratory applications.

Advice on applications not covered in this leaflet may be obtained from your Shell representative.

Performance Features and Advantages
• Very good oxidation stability
The selected mineral base oil for the formulation of Corena V is offering a very good natural resistance to oil degradation. This will ensure a long oil life, low tendency for building up sludge and deposits formation
• Sufficient low vapour pressure
The careful selection of the base oil is providing a very low vapour pressure of the oil because of the narrow boiling range. This will enable the machine to easily reach the vacuum it is designed for. It also helps to minimise the thickening of the oil because of light-end carry over.
• Corrosion protection
It will ensure proper rust protection to all components because the neutral behaviour of the oil.
• Good demulsibility
Corena V will offer a good demulsibility in order to keep the amount of moisture and water in the oil to a minimum.

Specification and Approvals
ISO 6743-3A-DVC
Shell Corena V is known and used to many key OEM’s throughout the world.

Application advice
Corena V should not be used in vacuumpumps running under conditions like very high temperatures and permanent service.
It should not be used when corrosive gases or vapours are involved in the extraction process.

Health and Safety
Guidance on Health and Safety are available on the appropriate Material Safety Data Sheet which can be obtained from your Shell representative.

Protect the environment
Take used oil to an authorised collection point. Do not discharge into drains, soil or water.
