Over the last century, construction machinery has become vital in our fast-paced world. The ongoing need to repair, upgrade, or expand neighbourhoods, roadways, and factories makes construction vehicles and equipment indispensable. To ensure these machines operate at peak performance, it is essential to maintain their integral components, particularly the hydraulic systems.
A hydraulic system is a mechanism that uses fluid energy, generated by compressing hydraulic oil, to produce power and offer precise control over machines and equipment. Examples of construction equipment with hydraulic systems include excavators, bulldozers, cranes, backhoes, loaders, and dump trucks. Additionally, smaller machines such as trenchers, concrete pumps, and cement mixers also rely on hydraulic technology.
The main functions of a hydraulic oil, which extend far beyond lubricating components, include:
When choosing fluids for construction hydraulic systems, there are three main types: mineral-based oils, synthetic fluids, and water-based fluids. The right fluid for a specific vehicle or equipment depends on factors like components, the operating temperature, pressure, technical features, and the requirements set by the manufacturer.
Hydraulic fluids have several important properties, including viscosity, lubrication, thermal stability, anti-wear characteristics, and oxidation resistance. Due to viscosity’s importance, international standards categorise it into viscosity classes. For hydraulic systems, the ISO VG classification is widely used, from VG 2 to VG 3200. Various systems require different oil types, leading to DIN and ISO standardised hydraulic fluids. Modern systems do not rely on base oil alone; hence, additive enhancements are essential. To these OEM specs are added for enhanced performance.
Enilive produces modern and advanced hydraulic fluids that meet the standards of various hydraulic systems. We offer mineral oil-based oils that are widely used for their effective lubrication and thermal stability. Further, we offer synthetic fluids which provide superior performance in extreme conditions, and water-based fluids that are used where fire resistance and environmental safety are essential.

The main functions of a hydraulic oil, which extend far beyond lubricating components, include:
- Power Transmission within the hydraulic system. When pressurised by a hydraulic pump, the fluid transmits force to cylinders and motors, enabling movement of parts such as booms, buckets, arms, and tracks.
- Heat Transfer. Hydraulic systems generate heat during operations. The fluid helps absorb and carry away this heat, preventing overheating and damage.
- Sealing. Hydraulic fluid acts as a sealant inside the hydraulic system, helping to prevent leakage of pressurised fluid and ensuring consistent power transfer.
- Corrosion and oxidation protection. It protects from oxidation, keeping the hydraulic system clean and minimising damage from contamination.
