HYDROL PREMIUM L-HM 32
|
General features
Hydrol® Premium L-HM hydraulic oils are manufactured basing on refined mineral oils and zinc free set of enriching additives.
Features:
High level operating properties:
– high thermal and hydrolytic stability,
– high resistance to oxidation,
– high ability to transfer loads (FZG test, breaking load >12) and very good antiwear properties,
– very good ability to be filtered,
– very good resistance to foaming,
– compatibility with sealants.
Hydrol® Premium L-HM can be mixed with other zinc free hydraulic mineral oils.
Application
High durability of Hydrol® Premium L-HM enables their application in highly loaded systems of power transmission as well as hydraulic drive and control operating in extremely high pressures and temperatures. New, unique formula used in the manufacturing process guarantees their extended lifetime compared to standard mineral hydraulic oils.
