Castrol Hyspin HLP-D68  Hyspin HLP-D Detergent Hydraulic Oil Description The Hyspin™ HLP-D hydraulic oil range of lubricants are based upon highly refined mineral oil enhanced with a zinc additive system. They also contain detergent ａnd dispersant additives. Application Hyspin HLP-D oils are for use primarily in machine tool hydraulic systems, gears ａnd clutch drives ａnd in mobile hydraulic systems used outdoors. These oils 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. The Hyspin HLP-D range is fully compatible with common seal materials. Hyspin HLP-D is classified as follows: DIN classification - HLP-D ISO 6743/4 - Hydraulic Oils Type HM Hyspin HLP-D grades meet the requirements of: DIN 51524 Part 2 (except for demulsification) Advantages • Smooth functioning of sliding parts in hydraulic systems ａnd machine tools. • Good surface wetting properties provide smooth sliding of seals on hydraulic pistons ａnd rods ａnd reduces corrosion. • Excellent corrosion protection in arduous conditions. • Maintains performance in ‘wet’ operating conditions, eg outdoor equipment, machining operations.
