PRODUCT DETAILS
Sinopec Ashless L-HM Hydraulic Oil
Sinopec Ashless L-HM Anti-Wear (AW) High-Pressure Hydraulic Oil is a premium hydraulic oil, formulated using carefully selected and refined high-quality mineral base oils combined with an advanced ashless additive system (zinc-free) and is available in a wide viscosity range from ISO 32 to 100.
Applications
- Industrial and Marine Hydraulic Systems: Suitable for systems operating under harsh conditions, high temperatures, and high pressures.
- Vane and Gear Pumps: Ideal for high-pressure and low-temperature operations as recommended by pump manufacturers.
- Heavy-Duty Hydraulic Systems: Suitable for axial and radial piston pumps as recommended by pump manufacturers.
Features & Benefits
- Non-Corrosive to Colored Metals: The ashless additive system (zinc-free) does not corrode colored metals, extending the life of pumps.
- Effective Anti-Wear Properties: Provides superior wear protection under high-pressure conditions, maintaining additive stability.
- Long Life: The ashless additives ensure the oil’s longevity, doubling the lifespan compared to conventional zinc-based hydraulic oils.
