Shell Tellus S2 MA 46
Shell Tellus S2 MA 46 is a high-performance detergent-based hydraulic fluid developed to provide reliable lubrication and protection in industrial hydraulic systems operating under demanding conditions. Formulated using advanced ashless anti-wear technology combined with detergent additives, Shell Tellus S2 MA 46 is designed for applications where emulsifiable fluids are preferred and where contamination from aqueous fluids or solid particles may occur. The formulation helps maintain system cleanliness and reliability while delivering dependable hydraulic performance across a wide range of operating conditions.
One of the key advantages of Shell Tellus S2 MA 46 is its ability to provide protection in challenging operating environments. The detergent additive system helps prevent water accumulation within the hydraulic fluid by dispersing moisture and contaminants throughout the oil. This helps minimise corrosion risks and ensures sensitive hydraulic components remain protected even in the presence of water contamination. Shell Tellus S2 MA 46 also delivers excellent anti-wear protection through its advanced ashless additive technology, helping reduce friction and protect pumps, valves and actuators from wear during heavy-duty operation.
Shell Tellus S2 MA 46 also offers strong load-carrying capability for hydraulic and geared systems. The fluid demonstrates excellent performance under boundary lubrication conditions where high loads and low speeds may occur. This protection helps prevent excessive wear and surface damage to critical components, supporting longer equipment service life and improved operational reliability in demanding industrial applications.
Maintaining system efficiency is another important benefit of Shell Tellus S2 MA 46. The formulation promotes superior cleanliness in severe environments, helping hydraulic systems continue operating efficiently even when contamination risks are present. Shell Tellus S2 MA 46 also offers excellent air release and anti-foam performance, ensuring smooth hydraulic power transmission and minimising performance losses caused by foaming or air entrainment. In addition, the fluid provides strong filterability characteristics that allow the use of fine filtration systems for improved equipment protection and longer system life.
Shell Tellus S2 MA 46 is particularly suited for industrial and manufacturing applications where system cleanliness and contamination control are critical. Typical applications include injection moulding machines, electronically controlled hydraulic equipment, mobile machinery and headstocks or hydraulic controls in automatic lathes where water-extendible metalworking fluids may be present. The fluid is also recommended for hydraulic systems where HLPD type oils are specified.
Physical characteristics include a kinematic viscosity of approximately 46 mm²/s at 40°C and 7 mm²/s at 100°C with a viscosity index of approximately 107. Shell Tellus S2 MA 46 has a density of approximately 877 kg/m³ at 15°C, a flash point of around 223°C and a pour point of approximately −24°C, supporting reliable hydraulic lubrication performance across a wide range of operating conditions.
