Mineral based high performance zinc free hydraulic fluid
High performance hydraulic fluid, based on the latest base oil and additive technology. The use of an ashless additive pack warrants optimum performance and a long service life. Because of the absence of metals like zinc Hydra ZF is extremely suitable for systems using bronze and silver components.
Applications
Hydra ZF can be used in all available hydraulic applications, as well as light gear boxes and is perfectly suitable for general lubrication purposes. This product is particularly recommended for hydraulic systems with high loads and/or with wear sensitivity requiring protection against gumming, deposits, and corrosion.
