Description
Castrol Hyspin™ AWH-M hydraulic oils are mineral oil based anti-wear hydraulic fluids which incorporate viscosity index improvers in order to enhance their viscosity – temperature performance for use in environments which are subject to low or widely variable temperatures. The high viscosity index can also allow a degree of rationalisation of hydraulic fluids across different equipment in order to reduce the number of lubricants carried on board.
Application
Hydraulic systems and hydrostatic tranmissions incorporating gear pumps, vane pumps, radial piston or axial piston pumps and motors.
