Shell Tellus S2 MA
Industrial Detergent Hydraulic Fluid
Shell Tellus S2 MA fluids are high performance detergent based hydraulic fluids for use where 
emusifiable fluids are preferred. Using proven ashless anti-wear technology they provide 
reliable performance in applications where contamination by aqueous fluids, such as cutting 
fluids, or where cleanliness or control of solid contaminants is important. 
Performance Benefits 
• Protection in severe environments 
The established detergent ａnd modern ashless antiwear technology in Shell Tellus S2 MA fluids 
provides extra protection in challenging 
environments by: 
– Preventing water accumulation 
– Dispersing solid contaminants 
– Preventing corrosion in presence of water 
– Providing low-friction anti-wear 
performance 
Outstanding anti-wear ａnd load-carrying 
properties in hydraulic ａnd geared systems, 
especially under high load ａnd low speed 
boundary lubrication conditions are demonstrated 
by the high Brugger ａnd FZG load values. 
• Fluid life – Maintenance saving 
Shell Tellus MA fluids have good resistance to 
thermal ａnd chemical breakdown to ensure 
consistent performance ａnd protection throughout 
the fluid drain interval. 
• Maintaining system efficiency 
Superior cleanliness in severe environments helps 
keep the hydraulic system functioning efficiently. 
This is supported by excellent air release ａnd antifoam characteristics. 
In addition, Shell Tellus S2 MA provides excellent 
filterability allowing the use of fine filters for extra 
protection ａnd long equipment life. 
Smooth operation of the hydraulic system is 
supported by the low-friction additive system that 
helps reduce stick-slip behaviour under high loads 
or poorly lubricated contacts. 
Shell Tellus S2 MA has a minimum cleanliness of 
max ISO 4406 21/19/16 class (ex Shell filling 
lines) as defined by DIN 51524 specification for 
extra equipment ａnd filter protection. As 
recognized by DIN 51524 specification, the oil 
is exposed to various influences with transport 
ａnd storage that could effect the cleanliness 
level. 
Applications 
• Industrial hydraulic systems
Shell Tellus S2 MA fluids are suitable for a wide 
range of industrial ａnd manufacturing applications 
including: 
– Injection moulding machines 
– Electronically controlled hydraulic equipment 
– Mobile equipment 
– Headstocks ａnd hydraulic controls in automatic 
lathes (when a synthetic or semi-synthetic waterextendible metal working fluid is used) 
Where low start up ａnd high service temperatures 
are encountered the use of Shell Tellus S2 VA 46 is
remended. 
Specifications ａnd Approvals 
Shell Tellus S2 MA fluids meet the requirements of:
ISO 11158 (HM fluids) 
ASTM 6158-05 (HM fluids) 
Shell Tellus S2 MA fluids are approved by 
• EXTRA PROTECTION 
• WATER TOLERANT

壳牌得力士（Tellus）S4 ME液压油  （原名：壳牌得力士EE液压油）

Shell Tellus S4 ME Oil

应用：

• 工业液压系统
特别适于注塑和高压五金冲压作业等高强度液压应用，以及要求耐受高温或提供较长使用寿命的工况。
• 移动液压系统
壳牌得力士S4 ME 也适用于某些移动液压传动系统和船舶应用，与大多数常规ISO HM 液压油相比，具有优良的低温流动性。
• 环境影响
相比于常规含锌液压油，在发生意外泄漏时，壳牌得力士S4 ME 液压油采用了无灰抗磨技术和低硫基础油，减少了对环境的影响。

性能优势
• 高能源效率
借助尖端的系统模型，壳牌得力士S4 ME经专门设计，实现了流量、摩擦和动能传输等特性的平衡，可提高液压系统的能源效率。现场使用表明，在此类应用中，能源效率平均提高了8%1。
• 降低维护费用
与所有液压油相关的特性，壳牌得力士S4 ME均具备出色的性能，如保护液压泵防止磨损，和在有水或其他污染物的情况下避免发生故障。
在工业透平油氧化稳定性试验（TOST）中测得的寿命超过1万小时。壳牌得力士S4 ME能大幅延长换油周期，有助于降低总的维护费用。
• 增强保护设备
除满足工业标准和OEM规范要求之外，壳牌得力士S4 ME可提供优异的额外保护能力。如，在Vickers V104C泵磨损试验中，壳牌得力士S4 ME的磨损结果比Cincinnati Machine（P规范）、Bosch-Rexroth（RD 90220-1）和Eaton（Vickers）等许多OEM设定的50 mg合格限值要低68%。壳牌得力士S4 ME具备优良的清洁度（出厂产品满足甚或超越ISO 440621/19/16要求，通过了DIN 51524标准的认可。但运输和储存中的多种因素会对清洁度造成影响）。其上杰出的保护能力，能防止形成油泥、阀门粘滞和腐蚀，该产品有助于延长液压设备的使用寿命。
