Pakelo Hydrosint AL ISO 46 is a Very High Viscosity Index lubricant recommended for hydraulic systems. The product is formulated with selected synthetic base stocks, high shear stable viscosity index improvers and an accurate Ash-Less additive package that provides anti-wear, antioxidant, antirust, anticorrosion and antifoam properties. Thanks to its chemical and physical characteristics the product has been developed for the most modern hydraulic systems working even under severe conditions.

Pakelo Hydrosint AL ISO 46 transfers power with great promptness and uniformity under all working and ambient conditions lengthening life of systems operating at high pressures, and/or at high pump speed (vane pumps, gear pumps, piston pumps, etc.).

The product provides the following properties:

• Very High Viscosity Index that enables minimum viscosity changes, if compared to common hydraulic lubricants, when the fluid is exposed to different operating temperatures;
• high shear stability: viscosity index improvers guarantee high resistance to mechanical stress and, during service, allow to maintain viscosities almost equivalent to new lubricant;
• very low Pour Point that enables easy start-ups at low temperatures;
• high anti-wear properties to increase efficiency, life of pumps and of the operating parts in the system;
• ash-less additive package, suitable also if there are pumps (i.e. LUCAS PM piston pumps with silver alloy components) with parts that can be spoiled by Zinc-Dithiophosphate additives traditionally used in hydraulic lubricants;
• very high thermal stability, also thanks to the use of synthetic base stocks, that allows the use of the product in hydraulic systems operating also at high temperatures and pressures without causing deposits and sludge;
• high oxidative stability that allows longer oil drain intervals and thus avoids early oil thickening;
• high hydrolytic stability which enables to protect the oil being used also when contaminated with small percentages of water;
• good demulsivity: the lubricant can easily separate from the water that could contaminate the system avoiding an accelerated process of oxidation;
• high filterability even with presence of water avoiding in this way filter plugging and guaranteeing longer filter life;
• anticorrosion and antirust capability to provide efficiently the protection of all metallic components of the hydraulic system;
• antifoam properties to avoid the presence of foam and air that reduce system efficiency due to the different compressibility ratio between lubricant and air/lubricant mix;
• compatibility with gaskets and metals normally used in hydraulic systems.
