HYDROL® L-HM/HLP
|
General features
Hydrol® L-HM/HLPhydraulic oils for hydrostatic systems are manufactured basing on high quality mineral base oils and a set of enriching additives improving antiwear, anticorrosive and antioxidative properties.
It provides:
- extended lifetime,
- reduces wear of hydraulic pump elements,
Application
Hydrol® L-HM/HLP Phydraulic oils are intended mainly for heavy-duty power transferring systems and for hydraulic driving and control systems i.e. hydraulic gears, control mechanisms and other alike devices operating in hard conditions or in increased temperature or humidity.
