Hydraulic Oil – Frequently Asked Questions
What is hydraulic oil and what are its main functions?
Hydraulic oil is a special medium for power transmission in hydraulic systems. It transmits pressure and motion, lubricates components, protects against corrosion, and contributes to system cleanliness. This ensures performance and service life of the system.
What does the designation "HLP" mean for hydraulic oil, and what does the number (e.g., 46) stand for?
HLP refers to hydraulic oils according to DIN 51524 Part 2 with additives for improved corrosion protection, oxidation stability, and wear protection. The number (e.g., 46) indicates the viscosity at 40 °C in centistokes (cSt). An HLP 46 is a medium-viscosity oil, suitable for various temperatures and applications.
Why is regular hydraulic oil change so important?
Regular oil changes maintain efficiency and protect the hydraulic system from damage. Fresh oil ensures:
- Efficient power transmission
- Optimal wear and corrosion protection
- Extended service life of components
Neglected oil maintenance can lead to failures and high repair costs.
When should hydraulic oil be changed?
The oil change depends on manufacturer, machine, and application. A change is recommended:
- In case of visible dirt or contamination
- If system performance decreases
- At least once a year, unless specific intervals are specified
Regular oil analyses and visual inspections help determine the optimal change interval.
What are the advantages of hydraulic oils with HLP additives?
- Improved wear and corrosion protection
- Efficient power transmission and low-friction movement
- Good oxidation stability
- Reliable air and water separation capability
In which areas is hydraulic oil typically used?
Hydraulic oil is essential in all sectors with hydraulic drives and steering systems, e.g.:
- Agriculture
- Construction
- Municipal engineering
What should be considered when selecting the right hydraulic oil?
Important selection criteria are:
- Suitable viscosity grade (e.g., HLP 46)
- Protective and additive properties
- Compatibility with machine and system
The correct choice ensures optimal performance and long service life of the system.
Which products, in addition to hydraulic oil itself, are relevant for maintenance and handling of hydraulic oil?
In addition to hydraulic oil, useful supplementary products are available, including:
- Oil absorbent mats: Various sizes, absorb oil but not water
- Oil absorbents Type III/R: For all types of liquids, including use on traffic areas
- Oil emergency kits: With absorbent mats, oil booms, waste bags, and gloves
- Filtration systems: For cleaning and reusing hydraulic oil
These products increase operational safety and simplify maintenance and emergency operations.
