CASTROL Hyspin HLP-D 68
Hydraulic Oils
Hyspin HLP-D 68 is for use primarily in machine tool hydraulic systems, gears and clutch drives and in mobile hydraulic systems used outdoors.
Hyspin HLP-D 68 can tolerate high levels of water contamination, either from the outdoors environment or by water miscible cutting oils when used in machine tool equipment, and still provide effective lubrication. Such contamination can cause corrosion and seizure of hydraulic components.
The detergent/dispersant properties of Hyspin HLP-D oils maintain the performance of hydraulic systems under these circumstances.
In hydraulic cylinders operating at low speeds, Hyspin HLP-D oils prevent erratic movement and stick/slip between seals and shafts, greatly reducing seal wear. Hyspin HLP-D oils are suitable for mobile equipment where multi-disc clutches are employed. They permit higher torques to be transmitted, and maintain smooth clutch operation, short engagement times, and low rates of clutch wear.
Hyspin HLP-D 68 is based on highly refined mineral oil enhanced with a zinc additive system. It also contains detergent and dispersant additives.
