Most hydraulic systems require the use of oil or an emulsion of oil and water as the working fluid and lubricant. Oil Free Hydraulic technology eliminates this need so that the impulsive unit is powered and lubricated by water alone.
The absence of oil and the special properties of water demand very high levels of precision engineering and exacting manufacturing standards but the benefits over oil-based systems are numerous, most notably greater production efficiencies and a cleaner, safer environment.
