HFD-U 46 HYDRAULIC OIL
HFD-U 46 Hydraulic Oil is an advanced, synthetic, anhydrous, less flammable hydraulic fluid based on organic esters and proven additives.
These ISO Class HFDU fluids are specially designed to provide good performance in conventional hydraulic systems and have better fire resistance than mineral oils. HFD-U 46 Hydraulic Oil is biodegradable with a low ecotoxicity and particularly suited for use in environmentally sensitive areas. Typical applications for HFD-U 46 Hydraulic Oil are to be found in the tunnel boring, metal, mining and glass industries. HFD-U 46 Hydraulic Oil can replace mineral oils in hydraulic installations to provide good lubrication and a higher degree of fire resistance.
- Lower flammability than mineral oils
- Readily biodegradable – >60% after 28 days when tested in OECD 301 B (CO2 evolution test)
- Excellent viscosity/temperature characteristics – minimum change of viscosity with variation in operating temperature, giving true ‘multigrade’ characteristics
Pump anti-wear protection similar to mineral hydraulic oils - Low flammability maintained during the life of the fluid
- Excellent corrosion protection
- Compatible with mineral oil and most materials/seals specified for use with mineral oils (not natural rubber)
Classification HFDU according to ISO 6743-4
ISO 12922 Specifications for fire-resistant hydraulic fluids – category HFDU
The European Communities Mines Safety Commission 7th Report – Requirements for less flammable fluids (‘7th Luxembourg Report’)
