Castrol Hyspin AWS 46 – 205 L Premium Anti-Wear Hydraulic Oil

Product Overview

Castrol Hyspin AWS 46 is a high-quality anti-wear hydraulic oil formulated for use in industrial and mobile hydraulic systems where ISO VG 46 performance is required. This premium hydraulic fluid provides reliable protection for pumps, valves, and hydraulic components operating under moderate to high pressure and temperature. Developed using highly refined mineral base oils and a zinc-based additive system, it delivers excellent wear control, corrosion protection, and oxidation stability, ensuring long equipment life and reduced maintenance downtime.

Designed for heavy-duty applications, the ISO 46 viscosity grade offers an optimal balance between flow performance and oil film strength, maintaining consistent operation in a variety of climates and workloads. The 205 litre drum size makes this product especially suitable for large-scale operations, workshops, and industrial facilities where bulk supply is essential for productivity and efficiency.

Key Features & Benefits

• Superior Anti-Wear Performance
  Formulated with a proven zinc-based anti-wear additive system that protects pumps and hydraulic components from friction and metal-to-metal contact, even under high loads and pressures.

• Excellent Oxidation and Thermal Stability
  Resists degradation and sludge formation during prolonged high-temperature operation, extending oil life and improving system cleanliness.

• Reliable Viscosity Control
  The VG 46 viscosity provides excellent film strength and flow performance across a wide range of operating temperatures, ensuring efficient operation in both industrial and mobile systems.

• Outstanding Rust & Corrosion Protection
  Prevents corrosion of ferrous and non-ferrous metals in hydraulic circuits, even in the presence of water contamination or humid conditions.

• Efficient Demulsibility (Water Separation)
  Rapidly separates water from oil, preventing emulsions that can damage system components and reduce lubrication efficiency.

• Low Foam Tendency
  Formulated with foam inhibitors to ensure consistent hydraulic response and prevent air entrainment and pump cavitation.

• Excellent Filterability
  Maintains performance through fine filtration systems, ensuring oil cleanliness and reducing filter replacement frequency.

• Seal Compatibility
  Compatible with common seal materials including nitrile, silicone, and fluorocarbon types, minimising the risk of leakage or seal degradation.

Handling & Storage Advice

• Store indoors in a cool, dry, and well-ventilated area, away from direct sunlight or ignition sources.

• Keep drums tightly sealed when not in use to prevent contamination from moisture or dust.

• Avoid prolonged exposure to temperatures above 60 °C or freezing conditions.

• When dispensing, always use clean hoses, pumps, and containers dedicated to hydraulic oil.

• Do not mix with oils of different performance levels or additive chemistries unless verified compatible.

• Ensure correct labelling and segregation of used and unused fluids.

• Dispose of used oil and containers through licensed waste management services in compliance with local environmental regulations.

• Refer to the Safety Data Sheet (SDS) for complete information on health, safety, and environmental precautions.

Advantages of Bulk 205 L Packaging

The 205 litre drum offers excellent value for high-volume users and maintenance facilities. It reduces purchasing frequency, minimises waste, and supports continuous operation in industrial environments. Bulk packaging also helps maintain consistent product quality across large applications by reducing the need for frequent small-batch transfers.

This format is ideal for:

• Workshops and heavy-equipment service centres

• Manufacturing plants with multiple hydraulic power units

• Fleet maintenance and construction equipment depots

• Centralised fluid management systems

Key Operational Benefits

• Longer service life compared to conventional hydraulic oils

• Enhanced pump protection under high pressure and load

• Reduced downtime through clean system operation and extended drain intervals

• Lower maintenance costs by preventing premature wear and component failure

• Compatible with a wide range of seals and materials, reducing the risk of leakage

• Excellent oxidation control leading to cleaner valves and lines

• Consistent viscosity performance even under fluctuating ambient temperatures
