Shell Fire-Resistant Hydraulic Fluid S3 DU 46

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. Shell FireResistant Hydraulic Fluid S3 DU 46 is readily biodegradable.
 

Performance, Features & Benefits of Shell Fire-Resistant Hydraulic Fluid S3 DU 46 are:

• Excellent fire resistance. Shell 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 protection. Shell 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 stability. Shell 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 formation. Shell 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°C.
• Suitable for all-weather service. A high viscosity index in combination with excellent lowtemperature fluidity provide a year-round fluid that protects the machine from cavitation at cold startups and provides durability at higher operating temperatures.
• Excellent compatibility. While 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.

Specifications of Shell Fire-Resistant Hydraulic Fluid S3 DU 46 are:

• FM Global
• Shell Fire-Resistant Hydraulic Fluid S3 DU 46 is classified as FM Approved industrial fluids by Factory Mutual and is readily biodegradable with biodegradability of over 60% after 28 days in the OECD 301 B carbon dioxide evolution test. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 meets or surpass Bosch-Rexroth, Sauer-Danfoss, Denison, Parker, Oilgear, and Eaton (Formerly Vickers) specification.
