Shell Omala S4 WE 320 20L 

GZ Industrial Supplies is the distributor and supplier of Shell Lubricants in Nigeria. This Shell Omala S4 WE 320 20L is an advanced synthetic heavy duty industrial worm drive gear oil formulated using specially selected polyalkylene glycol base fluids and additives. It offers outstanding lubrication performance under severe operating conditions, including improved energy efficiency, long service life and high resistance to micro-pitting.

Main Applications of Shell Omala S4 WE 320 20L

Enclosed industrial worm gear systems

Recommended for industrial worm gear reduction systems operating under severe operating conditions, such as high load, very low or elevated temperatures and wide temperature variations.

Extended life systems

Shell Omala S4 WE is particularly recommended for certain systems where maintenance is infrequent or systems are inaccessible (eg. yaw gears in wind turbine installations).

Other applications

Shell Omala S4 WE oils are suitable for lubrication of bearings and other components in circulating and splash-lubricated systems.

Shell Omala S4 WE is not recommended for the lubrication of components manufactured from aluminium or aluminium alloys.

For highly-loaded spur and helical gears the Shell Omala “G” series oils are recommended.

For automotive hypoid gears, the appropriate Shell Spirax Oil should be used.

DIN 51517-3 (CLP)

Fully approved by Bonfiglioli

Seal & Paint Compatibility

High quality epoxy paints are recommended, as polyalkylene glycols will tend to attack certain conventional paints. Shell Omala S4 WE has been found to be satisfactory with nitrile and Viton seal materials, although Viton seals are preferred.

Change-over Procedure

Shell Omala S4 WE contains polyalkylene glycols and is not compatible with mineral oils or most other synthetic lubricant types. Care should be taken when changing from such products to Shell Omala S4 WE.

The system should be flushed with the minimum quantity of Shell Omala S4 WE operating under no load and draining whilst warm. Ideally, seals exposed to mineral oils should also be replaced. Inspect the lubricant after a few days use. Ensure that oil systems are clean and free from contamination.

Shell Omala S4 WE is also not miscible with some other polyalkylene glycols, so caution is needed when topping-up. Generally the preference is to avoid mixtures by draining and refilling.
