Manufacturer's description

Advanced Fire Resistant (HFDU) Synthetic PAG Hydraulic Oil. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 is a synthetic fire-resistant hydraulic fluid, based on very high VI, polyalkylene glycol (PAG) base stocks, coupled with a proven ashless additive package. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 has been designed to minimize fluid degradation and thus extend fluid changeout intervals under even the most severe operating conditions. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 provides the performance properties demanded by today’s high-performance hydraulic systems. At least 97% by mass of this lubricant's components are readily biodegradable, achieving a passing result of ≥60% according to OECD 301B.

Applications

• Hydraulic fluidShell Fire-Resistant Hydraulic Fluid S3 DU 46 can be used as the hydraulic fluid in industrial and mobile equipment, including high-pressure systems, hydrostatic drives, systems with servo valves, and robotics.

Performance & benefits

• Excellent fire resistanceShell Fire-Resistant Hydraulic Fluid S3 DU 46 is inherently fire-resistant and is FM Approved, offering high flash point, high fire point and high auto-ignition temperature. It minimizes the risk of fire, which could potentially be caused by mineral oil products.
• Enhanced system protectionShell Fire-Resistant Hydraulic Fluid S3 DU 46 offers excellent lubricity, for outstand pump life under the most severe conditions. The fluid meets or exceeds the pump performance of premium, anti-wear mineral oils, even at 5,500 psi (380 bar) operating pressure. Shear stability is excellent. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 achieved a 13-stage rating in the FZG Gear Test demonstrating a high level of protection against wear and scuffing.
• Good hydrolytic stabilityShell Fire-Resistant Hydraulic Fluid S3 DU 46 will not break down and react with water, minimizing fluid degradation and acid formation that can damage and eventually destroy hydraulic pumps. No acid removal/ion exchange filters are required.
• High resistance to sludge or varnish formationShell Fire-Resistant Hydraulic Fluid S3 DU 46 is formulated to provide high resistance against varnish and sludge formation. Field experience has shown long-term system cleanliness while extending maintenance intervals and service life. In addition, this fluid is very stable at high temperatures and resistant to thermal degradation up to 120 0 C.
• Suitable for all-weather serviceA high viscosity index in combination with excellent low- temperature fluidity provide a year-round fluid that protects the machine from cavitation at cold startups and provides durability at higher operating temperatures.
• Excellent compatibilityWhile Shell Fire-Resistant Hydraulic Fluid S3 DU 46 is compatible with many different types of fluids, to ensure proper system performance, it is recommended to properly clean and flush hydraulic systems during conversions. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 is compatible with commonly used seals, hoses and metals. Detailed flushing procedures and compatibility data are available upon request.
• Shell Fire-Resistant Hydraulic Fluid S3 DU 46 is classified as FM Approved industrial fluids by Factory Mutual
• At least 97% by mass of this lubricant's components are readily biodegradable, achieving a passing result of ≥60% according to OECD 301B
• Shell Fire-Resistant Hydraulic Fluid S3 DU 46 meets or surpass Bosch-Rexroth, Sauer-Danfoss, Denison, Parker, Oil gear, and Eaton (Formerly Vickers) specification. For full listing of equipment approvals and recommendations
