HLP Hydraulic Oil is a premium mineral-based hydraulic fluid formulated according to DIN 51524 Part 2, engineered for hydraulic systems that operate under high pressure, continuous load, and demanding conditions. Enhanced with anti-wear (AW) additives, rust inhibitors, oxidation stabilizers, and foam-control agents, HLP oil provides reliable lubrication and long-lasting performance in both industrial and mobile hydraulic applications.

With its superior wear protection, excellent thermal stability, and strong resistance to oxidation, HLP Hydraulic Oil ensures maximum efficiency and durability for hydraulic pumps—especially vane, piston, and gear pumps—which require highly stable fluid performance under elevated pressures and varying temperature conditions.

Key Performance Features

1. Advanced Anti-Wear Protection (AW)

Formulated with zinc-based (ZDDP) or ashless anti-wear additives, HLP oil forms a protective film on pump and valve surfaces, preventing abrasion, scoring, and premature component wear.

2. Excellent Thermal & Oxidation Stability

Designed to resist oil thickening, deposits, sludge formation, and thermal degradation. This stability ensures extended service intervals and clean system operation.

3. Superior Corrosion and Rust Resistance

Protects ferrous and non-ferrous metal components from water contamination, moisture exposure, and chemical corrosion.

4. Low Foaming & Fast Air Release

Minimizes foam formation and ensures rapid deaeration, preventing cavitation, pump damage, and performance losses.

5. High Load-Carrying Capability

Delivers stable lubrication under high-pressure operation, shock loading, and rapid cycling common in modern hydraulic systems.

6. Excellent Filterability

Maintains cleanliness and prevents filter clogging even in systems with fine filtration, supporting reliable and consistent hydraulic response.
