Hydraulic oils are essential for the smooth running of many machine operations.
Whether it’s powering a heavy-duty construction vehicle or providing lift in an industrial setting, getting the right oil is critical to performance and longevity.
Different types and grades affect viscosity levels, which directly influence how efficiently and quickly your machines operate.
So it’s important to understand which grade you should be using — particularly when it comes to mixing 32-grade hydraulic fluids with 46-grade ones.
Read on as we explore this topic in more detail, exploring whether it’s possible (and if so, what approach you should take).
Can You Mix 32 And 46 Hydraulic Oils?
Yes, you can mix hydraulic oil with the same viscosity and different brands, but it is not recommended to mix oils with different additive packages as it can compromise their performance and cause corrosion.
Mixing two lubricants of the same type but different viscosities can also affect the lubricant inside the system.
If you are using different types of hydraulic fluids, make sure they are environmentally acceptable and work well together.
Remember to always check the requirements for the machine before mixing hydraulic oils.
Difference between 32 and 46 hydraulic oil
Choosing the right hydraulic oil that matches your equipment’s operating conditions and production specifications is critical.
Viscosity
One of the primary differences between 32 and 46 hydraulic oil is their viscosity.
Viscosity is the fluid’s resistance to flow, and it determines how easily the oil flows through hydraulic components.
A lower viscosity oil, such as 32 hydraulic oil, is thinner and flows more easily, making it ideal for use in systems that operate in cold temperatures.
Conversely, higher viscosity oil, such as 46 hydraulic oil, is thicker and flows more slowly, making it a better option for systems operating in high heat or under heavy loads.
Oxidation Resistance
Another crucial difference between these two hydraulic oils is their oxidation resistance.
Oxidation is the process by which the hydraulic oil reacts with air and breaks down over time. The breakdown of oil can cause equipment damage, malfunctioning and even failure eventually.
The 46 hydraulic oil is known for its high oxidation resistance, which means it lasts much longer before breaking down.
Contrarily, 32 hydraulic oil has lower oxidation resistance and requires more frequent oil changes; therefore, it is not as suitable for equipment that requires optimal durability and resiliency.
Performance
Another key difference between 32 and 46 hydraulic oil is their performance in different equipment.
32 hydraulic oil offers greater efficiency when used in low-pressure situations, whereas 46 hydraulic oil is better suited for high-pressure equipment.
Systems operating at higher operating pressures will benefit significantly from 46 hydraulic oil, which offers superior lubrication and reduces wear and tear on hydraulic components.
Equipment Application
Lastly, when selecting hydraulic oil, the type of equipment and its manufactures specification is always to be considered.
A major difference between 32 and 46 hydraulic oil is the range of equipment they can be used for.
32 hydraulic oil is suitable for use in less demanding hydraulic systems like tractors and other construction equipment.
46 hydraulic oil, on the other hand, is ideal for heavy-duty hydraulic presses, conveyors, and hydraulically-operated machinery.
Will mixing 32 and 46 hydraulic oil cause damage?
mixing hydraulic oil with different additives is not recommended as it can cause severe damage to the machine in case the mixing fails.
While you can mix 32 and 46 oil, it is not recommended as it can influence the viscosity of the oil.
Hydraulic oils have different viscosity levels, and mixing different grades can lead to issues with the lubrication of the machine.
If you have an older machine that tends to leak oil, you can consider using a thicker 46 oil to compensate for the loss.
However, it is essential to use the correct type of oil for your machine to ensure smooth running and extended lifespan.
Conclusion
It is important to know the specific viscosity of the hydraulic oils you are working with in order to determine if they can be safely mixed together.
The recommended viscosity for 32 and 46 hydraulic oils is ISO 32 and ISO 46 respectively, though there are other viscosities as well.
Generally speaking, mixing these two types of hydraulic oils should not pose any problems or safety risks in fact, some may find that doing so will provide a better performance overall.
It is advisable to periodically change out all hydrostatic fluids, including both electrical and directional control fluids.
Lastly, it is highly recommended that when changing out any type of fluid in your machinery, you dispose of the old fluid in an environmentally friendly manner.
All in all, being aware of your machinery’s needs and capabilities will ensure safer operations for everyone involved in a manufacturing environment.
