Tellus S3 M

Premium Ashless Industrial Hydraulic Fluid

Performance Benefits

Long fluid life – maintenance saving

Shell Tellus S3 M fluids offer an improved capability to extend fluid maintenance intervals and hence reduce equipment downtime through:

• an extended ASTM D 943 TOST lifetime, with an oxidative stability that is up to three times longer than the industry minimum 
• excellent resistance to breakdown in the presence of water and heat.

These features provide extended maintenance capability without compromising protection or performance, even under severe or extended temperature range applications.

Outstanding wear protection

Advanced ashless (zinc-free) anti-wear additives provide protection over a wide range of conditions, including low and severe duty, and high load operation. This protection has been demonstrated in tough industry standard hydraulic pump tests such as the Denison T6C (dry and wet versions),  Denison P46 and Eaton Vickers 35VQ25 tests.

Maintaining system efficiency

Superior cleanliness and filterability; coupled with excellent water separation, air release and  anti-foam characteristics, all help to maintain or enhance hydraulic system efficiency.

The filterability of Shell Tellus S3 M is maintained even when the fluid is contaminated with water.

Shell Tellus S3 V fluids have a ISO 4406 cleanliness of 21/19/16 or better ex Shell filling lines. As recognized by DIN 51524 specification, the oil is exposed to various influences with transport and storage that could effect the cleanliness level

Applications

Manufacturing and industrial hydraulic systems

Shell Tellus S3 M fluids are suitable for a wide range of hydraulic power applications found in manufacturing and industrial environments.

Severe duty hydraulic service

The long-life characteristics of Shell Tellus S3 M fluids can make them particularly suitable for severe duty (e.g. load, temperature) applications or where extended life is required (e.g. remote or inaccessible locations).

Marine and mobile hydraulic systems

Shell Tellus S3 M fluids are suitable for marine and mobile applications where ISO HM type hydraulic fluids are recommended.

Environmental impact

Shell Tellus S3 M has a reduced environmental impact in the event of a leak or accidental spillage compared to conventional zinc-based hydraulic fluids. This is achieved through the use of ashless anti-wear technology and low sulphur base oils.

For applications that experience wide temperature variations we recommend the Shell Tellus “V” series of hydraulic fluids.

Specifications and Approvals

Shell Tellus S3 M fluids have the following approvals:

• Denison Hydraulics (HF-0, HF-1 and HF-2)
• Eaton Vickers (Brochure 694)
• Cincinnati Machine (P-68, P-70 and P-69).

Shell Tellus S3 M fluids meet or exceed the requirements of the following standards:

• ISO 11158 (HM fluids)
• DIN 51524-2 (HLP oils)
• ASTM 6158 (HM mineral oils)
• SS 15 54 34

Compatibility

Shell Tellus S3 M fluids are suitable for use with most hydraulic pumps.

Fluid Compatibility

Shell Tellus S3 M fluids are compatible with most other mineral oil based hydraulic fluids. However, mineral oil hydraulic fluids should not be mixed with other fluid types (e.g. environmentally acceptable or fire-resistant fluids).

Seal and Paint Compatibility

Shell Tellus S3 M fluids are compatible with seal materials and paints normally specified for use with mineral oils.

Protect the Environment

Take used hydraulic fluid to an authorized collection point. Do not discharge into drains, soil or water.

Typical Physical Characteristics

These characteristics are typical of current production. Whilst future production will conform to Shell's specification, variations in these characteristics may occur.
