Description
Product Description
Mobil Hydraulic Oil HLPD series are hydraulic fluids containing a selective additive system, for protection of hydraulic systems, plus the addition of detergent/dispersant additives. Contaminants, deposits and water which may have entered the hydraulic system can damage pump parts, with Mobil Hydraulic HLPD series these are dispersed and held in suspension, and adhering particles/deposits are dissolved.
Features and Benefits
| Features | Advantages and Potential Benefits |
| Emulsion forming properties | Emulsifies water and water mixed cooling fluids, without
deteriorating the good anti-corrosion and lubrication properties |
| Special detergent/dispersant additive system | Excellent keep-clean performance in the hydraulic system |
| Particular polar additives | Improvement of glide behaviour and prevention of stick-slip, even
under severe operating conditions |
Applications
Mobil Hydraulic Oil HLPD series are suited for use in hydraulic systems, where due to high ingresses of water or contamination a high level of dispersancy is required to prevent water dropout in the system. Mobil Hydraulic Oil HLPD series are particularly recommended for use in hydraulic systems of machine tools, where watermixed cutting fluids may enter the hydraulic system. They can also be used in applications that experience high levels contamination e.g. mobile hydraulic units (excavators, bulldozers, wheel loaders, truck hydraulic systems).
