Hydraulic oil is a non-compressible fluid generally used to transfer pressure energy in a hydraulic system. Depending on the machine or hydraulic equipment specification you may require different types of hydraulic fluids.
Anti-wear with HLP hydraulic oil would be best for you for the most common hydraulic applications. But it may increase your cost if not select the oil according to system requirements. In this blog post, we will discuss the selection of hydraulic oil & HLP 46 hydraulic oil.
What is a Hydraulic System?
It is a kind of mechanical system that works based on pascal’s law. In this system getting pressure and energy output needs a medium. Hydraulic oil is the only best medium for this system.
There are a lot of hydraulic oils around you. Out of them, HLP Hydraulic oil is the most commonly used for better output. Another important thing is the ISO viscosity grade. Generally, ISO 32,46,68 & 100 ISO Grade Hydraulic oil is mostly used.
Hydraulic Oil Selection
Most all hydraulic systems would be operated by transmission oil, Multigrade engine oil, anti-wear hydraulic oil, HLP hydraulic oil, or HVI hydraulic Oil. You have to know the actual application & operational condition of your system and then have to select hydraulic oil accordingly.
Selecting the type of Hydraulic Oil:
Depending application of hydraulic oil, hydraulic oil can be divided into a few types.to select the right hydraulic oil you have to determine the proper application of your hydraulic system, for example, if your system has a risk of firing then you need to select fire-resistant hydraulic fluid. On the other hand, if your system exits oil directly to the environment then you should think about biodegradable hydraulic oil. According to application type hydraulic oil would be classified into a few types, such as
- Mineral-based hydraulic oil
- Synthetic base hydraulic oil
- Fire resistance hydraulic oil
- biodegradable hydraulic oil
- Transmission gear & hydraulic oil
- Food-grade hydraulic oil
But you may find more types of customized hydraulic oil depending on hydraulic system requirements.
Selecting the grade of Hydraulic Oil:
First of all, find out your application type then you will be able to select the Viscosity grade of your required hydraulic oil. The table below may help you. Mind you, this is not the rule. it’s just to give you an idea to select the right hydraulic oil grade selection.
| Application types | ISO VG Grade |
| Power steering or brake fluid | 15 |
| Air tools in aircraft | 22 |
| High power machine tools | 32 |
| Industrial application of high pressure | 46 |
| Very high pressure & load | 68 |
You can also take the decision of selecting Hydraulic oil according to the component type. See the table below:
| Type of component | Minimum viscosity Permissible | Minimum viscosity Optimum |
| External Gear | 10 | 25 |
| Internal Gear | 20 | 25 |
| Axial Piston | 10 | 16 |
| Radial Piston | 18 | 30 |
| Vane | 25 | 25 |
HLP 46 Hydraulic Oil
It is a kind of pressure fluid used in different types of hydraulic systems. Hydraulic systems are used in a variety of machines and equipment, such as excavators, bulldozers, and cranes, or in any industrial applications. HLP 46 hydraulic oil is designed to protect against corrosion & wear. It also has high load caring capacity & oxidation stability.
HLP 46 hydraulic oil is important because it helps to keep the moving parts in hydraulic systems operating smoothly. If the moving parts in a hydraulic system are not properly lubricated, they can wear down quickly and cause the machine to break down. By using hlp 46 hydraulic oil, you can help to extend the life of your equipment and keep it running smoothly.
Types of HLP 46 hydraulic oil
There are two main types of HLP 46 hydraulic oils, mineral-based oils, and synthetic-based oils. Mineral-based hlp 46 hydraulic oils are made from refined petroleum product base oil. Synthetic-based hlp 46 hydraulic oils are man-made and designed to provide superior performance in extreme temperatures. Both types of hlp 46 hydraulic oils have advantages and disadvantages, so choosing the right hlp 46 hydraulic oil for your specific application is important.
If you are not sure which hlp 46 hydraulic oil is right for your machine, consult your owner’s manual or contact a qualified technician. Once you have selected the correct hlp 46 hydraulic oil, be sure to follow the manufacturer’s recommendations for changing and storing the oil. With proper care, hlp 46 hydraulic oil can help keep your equipment running smoothly for years to come.
Advantages of using HLP 46 Hydraulic Oil
Some of the advantages of hlp 46 hydraulic oil include:
– Excellent thermal stability
– Good oxidation resistance
– Good anti-wear properties
– Good corrosion protection
– Low chances of hydraulic leak
Application of HLP 46 hydraulic oil
HLP 46 Hydraulic Oil can be used in a wide variety of applications, including construction equipment, forestry equipment, and agricultural machinery. It is also suitable for use in many industrial applications such as plastic injection molding machines and metalworking machinery.
If you are looking for a high-quality hlp 46 hydraulic oil, consult your owner’s manual or contact a qualified technician to find the right product for your needs. With proper care and maintenance, hlp 46 hydraulic oil can help keep your equipment running smoothly for years to come.
Make sure you are using the correct hlp 46 hydraulic oil in your equipment to get the most out of it. Consult your owner’s manual or a qualified technician to find the right product for your needs.
Your Component may require Hydraulic 68 or Hydraulic grease also.
