What is hydraulic oil?

Hydraulic oil is a type of fluid that is specifically designed to power hydraulic systems, such as those found in heavy machinery, aircraft, and automobiles. It serves as a medium for transmitting power by converting mechanical energy into hydraulic energy.

The oil is specially formulated to provide the necessary lubrication and viscosity required to operate the system effectively. Hydraulic oil also contains additives that help prevent rust, oxidation, and foam formation, as well as improve its resistance to wear and tear.

This type of oil can be made from various base oils, including mineral oils, synthetic oils, and biodegradable oils, depending on the specific needs of the system. It is an essential component of hydraulic systems and plays a critical role in ensuring their smooth and efficient operation.

What are symptoms of a hydraulic leak?

Hydraulic leaks are a common issue that can occur in hydraulic systems, such as those found in heavy machinery, aircraft, and automobiles. If left untreated, a hydraulic leak can lead to significant damage to your equipment, increased downtime, and costly repairs.

One of the first steps in addressing a hydraulic leak is identifying the symptoms of the problem.

  • Reduced performance of hydraulic equipment
  • Decreased hydraulic pressure
  • Puddles or stains of hydraulic fluid on the ground or on the equipment
  • Unusual noises, such as hissing or whining
  • Burning smell caused by hydraulic fluid coming into contact with hot surfaces

What are possible causes of hydraulic leakage?

Hydraulic leakage can be a common problem in hydraulic systems, such as those used in heavy machinery, construction equipment, and vehicles. Identifying the root cause of the problem is the first step in fixing the issue.

There are several potential causes of hydraulic leaks:

  • Age-related wear and tear of seals and other components
  • Damage caused by external factors such as impact and vibration
  • Improper installation or maintenance, such as loose connections or incorrect torque
  • Overheating of the hydraulic fluid
  • Contamination of the hydraulic fluid by dirt, water, or other substances
  • Use of incompatible or incorrect hydraulic fluid

How to fix a hydraulic leak?

Have you found a leak? Then make sure that this is resolved gently and safely. Lindemann has the HYD-SL (Hydraulic Stop Leak) for this and this product is suitable for all types of hydraulic systems. It seals and / or reduces hydraulic oil leakage.

This hydraulic leak stop product consists of Teflon particles and contains anti-wear, anti-foam, anti-oxidation and anti-corrosion additives that reduce wear, noise and leakage.

There are additives on the market that can remedy leakage in hydraulic systems. Lindemann HYD-SL has something extra and brings the synthetic rubber gaskets back to their original flexibility so that they regain their original function.
