Mobil Pyrotec HFC 46
Mobil Pyrotec HFC 46 is a water glycol fire-resistant hydraulic fluid developed to provide enhanced safety and reliable performance in hydraulic systems operating under severe service conditions. It is specifically designed for systems where fire hazards are present, while still delivering strong lubrication and equipment protection.
One of the key advantages of Mobil Pyrotec HFC 46 is its inherent resistance to fire hazards. The water glycol formulation helps reduce the risk of ignition in high-temperature environments, making it suitable for applications where conventional mineral oil hydraulic fluids may pose a safety risk.
Mobil Pyrotec HFC 46 also provides excellent anti-wear performance. The formulation helps protect pumps and hydraulic components, including vane, gear and piston pump systems, extending equipment life and maintaining reliable system operation.
Another important benefit is its high oxidation resistance and shear stability. These properties help extend fluid life, maintain viscosity performance and reduce maintenance requirements in demanding operating environments.
Mobil Pyrotec HFC 46 also offers enhanced corrosion protection and seal compatibility. This helps protect system components and ensures reliable operation across a wide range of industrial applications. The fluid is FM approved as a fire-resistant industrial hydraulic fluid.
The product is recommended for hydraulic systems using vane, gear and piston pumps, particularly in industries such as steel, aluminium and die-casting operations. It is also suitable for hydraulic and oil circulation systems operating in conditions where fire resistance is required.
Physical characteristics include ISO viscosity grade 46 with a kinematic viscosity of approximately 46 cSt at 40°C and a viscosity index of around 195. Mobil Pyrotec HFC 46 has a pour point of approximately −50°C and a copper corrosion rating of 1B. The fluid has a red appearance and provides reliable performance in fire-resistant hydraulic applications.
