Typical characteristics

Manufacturer's description

Shell Tellus S2 MA are high-performance hydraulic fluids with detergent properties, for use where emulsifiable fluids are preferred. Because they use ashless anti-wear technology, they deliver reliable performance in applications where contamination with aqueous fluids, such as cutting fluids, occurs, or where cleanliness or the control of solid contaminants is important. This grade is ISO VG 46: kinematic viscosity 46 mm²/s at 40 °C and 7 mm²/s at 100 °C, viscosity index 107, pour point -24 °C. The data sheet lists Arburg and Müller Weingarten for ISO 46 only.

Applications

• Industrial hydraulic systemsIndustrial and manufacturing applications, including: plastic injection moulding machines; electronically controlled hydraulic equipment; mobile equipment; headstocks and hydraulic controls of automatic lathes (where synthetic or semi-synthetic emulsifiable metalworking fluids are used). All hydraulic systems for which an HLPD oil is specified. Shell Tellus S2 VA 46 is recommended for operating conditions with low start-up and high working temperatures.

Performance & benefits

• Protection in severe environmentsThe modern detergent and anti-wear technology used in Shell Tellus S2 MA fluids provides additional protection in severe environments by: preventing water accumulation; dispersing solid contaminants; preventing corrosion in the presence of water; delivering low-friction anti-wear performance. The excellent anti-wear and load carrying properties in hydraulic and gear systems, particularly under high-load, low-speed lubrication conditions, have been demonstrated by high Brugger and FZG load values.
• Service life – reduced maintenanceShell Tellus S2 MA fluids have good resistance to thermal and chemical breakdown, ensuring consistent performance and protection throughout the drain interval.
• Maintaining system efficiencyA superior degree of cleanliness under severe environmental conditions maintains efficient hydraulic system operation. This is supported by excellent air release and anti-foam characteristics. In addition, Shell Tellus S2 MA provides excellent filterability, allowing the use of fine filters for additional protection and long equipment life. Smooth hydraulic system operation is supported by the low-friction additive system, which helps reduce stick-slip behaviour. As recognised by the DIN 51524 specification, the oil is exposed to various influences during transport and storage that may affect its cleanliness level.
• Industrial hydraulic systems: Industrial and manufacturing applications, including: plastic injection moulding machines; electronically controlled hydraulic equipment; mobile equipment; headstocks and hydraulic controls of automatic lathes (where synthetic or semi-synthetic emulsifiable metalworking fluids are used). All hydraulic systems for which an HLPD oil is specified. Shell Tellus S2 VA 46 is recommended for operating conditions with low start-up and high working temperatures
• Compatibility: Shell Tellus S2 MA fluids are compatible with most types of hydraulic pump
• Fluid compatibility: Shell Tellus S2 MA fluids are compatible with most mineral oil based hydraulic fluids. However, hydraulic fluids must not be mixed with other fluid types (e.g. environmentally acceptable or fire-resistant fluids)
