Hydraulic oils
HYDROL® L-HV
|
General features
Hydrol® L-HVhydraulic oils are manufactured basing on high quality base oils and a set of enriching additives. They are featured by high level of antiwear properties and additionally improved temperature depending viscosity grades compared to L-HM hydraulic oils.
It provides:
- extended life time,
- reduction of wear of hydraulic pumps elements,
- work at wide range of temperatures with perfect viscosity preserved (high viscosity grade: WL > 140).
Application
Hydrol® L-HVhydraulic oils are intended for high loaded powering systems of high pressure piston pumps with constant and variable delivery and for sliding-vane pumps, where high antiwear oil properties are required and for precise systems of hydraulic control and hydraulic systems which require insignificant viscosity changes with temperature changes.
