Description
Rosneft Gidrotec ZF HVLP is a multi-grade zinc-free hydraulic oil with a high performance level. It is produced based on highly refined mineral oils and an ash-free additive package providing high antioxidant, anticorrosion and anti- wear properties.
Application
Rosneft Gidrotec ZF HVLP hydraulic oils are designed for all-season use in hydraulic systems of construction, road, logging, hoisting-and-transport equipment and other machines and units operating in a wide temperature range.
Approvals and specifications
Viscosity grades: ISO VG: 15, 22, 32, 46
Specifications and approvals: DIN 51524-3 (HVLP), Sulzer, Kirovsky Zavod, OJSC
Benefits
• Excellent low-temperature properties allow quick start-up of hydraulic systems without additional heating, reducing start-up time and wear of friction units when operating with cold oil;
• Designed for hydraulic systems of modern mobile equipment with copper and silver elements;
• Due to the absence of metal-containing compounds, the oil does not form deposits in the hydraulic system, which prevents the valves from “sticking” during operation, reduces the oxidation level and uncontrolled increase in the oil viscosity caused by the deposit dissolution;
• Improved air separation reduces the possibility of cavitation during the operation of high- speed hydraulic pumps, distribution and control valves, ensures the oil pressure stability;
• Oils of this series do not pollute the environment with heavy metals and zinc.
