YEFE Hydra ZF 46 is a high-performance ashless zinc-free anti-wear hydraulic oil developed for hydraulic systems, power transmission units and general lubrication operating under moderate to severe conditions. Formulated with high-quality virgin mineral base oils and a carefully selected performance additive package, it delivers excellent thermo-oxidative stability, strong anti-wear protection and superior demulsibility to ensure fast separation between water and oil.

This zinc-free technology is particularly suitable for systems that include diverse metals such as silver and silver-plated components in older hydraulic pumps, or where potential fluid spillage raises environmental concerns. YEFE Hydra ZF 46 helps extend pump and component life, minimize downtime and maintain reliable hydraulic performance in industrial and mobile equipment requiring HLP-class hydraulic fluids.

YEFE Hydra ZF 46 is based on virgin mineral base oils combined with an ashless additive system that provides anti-wear performance without zinc-containing components, making it compatible with a wide range of metals including silver and silver-plated parts in older hydraulic equipment. The fluid meets DIN 51524-2 (HLP) requirements and offers excellent thermo-oxidative stability to help control sludge and varnish formation and support extended oil drain intervals.

Dedicated rust and corrosion inhibitors protect metal surfaces even in the presence of water, while fast air release properties help minimize the risk of pump cavitation in high-pressure systems. Superior demulsibility promotes rapid water-oil separation in reservoirs, and the formulation is compatible with most sealing materials commonly used in hydraulic systems.
