Hydraulic Fluid

Which Hydraulic Fluid Is Right for Your Machinery?

When it comes to hydraulic systems, the choice of hydraulic fluid is crucial. Hydraulic fluid plays a vital role in hydraulic machinery’s overall performance and efficiency.

It not only lubricates the system but also transfers power and provides smooth operation. In this section, we will explore the different types of hydraulic fluid and their specific applications.

Mineral Oil-Based Hydraulic Fluids

Mineral oil-based hydraulic fluids are the most commonly used type. They are affordable and readily available, making them a favored option for a broad range of applications.

These fluids are ideal for hydraulic systems that operate within normal temperature ranges. They have good lubricating properties and provide adequate protection against wear and tear.

However, they can break down at high temperatures, limiting their suitability for extreme conditions.

Synthetic Hydraulic Fluids

Synthetic hydraulic fluids are specially formulated to withstand extreme temperatures and harsh operating conditions. They are highly resistant to thermal breakdown, making them ideal for hydraulic systems that operate under high temperatures or in cold climates.

Synthetic fluids offer superior lubrication and have a longer lifespan than mineral oil-based fluids. They also provide better resistance to oxidation and corrosion.

As a result, they are often used in heavy-duty applications such as hydraulic railroad jacks, air motor jacks, and heavy-duty jacks.

Biodegradable Hydraulic Fluids

Biodegradable hydraulic fluids are gaining popularity due to their environmental advantages. These fluids are made from renewable resources and have a minimal impact on the ecosystem.

They are commonly used in applications where there is a risk of accidental fluid leakages, such as hydraulic systems in marine environments or areas with sensitive ecosystems. Biodegradable fluids offer similar performance characteristics to mineral oil-based fluids but are more expensive and can have a shorter lifespan.

Fire-Resistant Hydraulic Fluids

Fire-resistant hydraulic fluids are specifically designed to minimize the risk of fire hazards in hydraulic systems. They are often utilized in applications with a high risk of fire, such as steel mills, foundries, and aircraft hydraulic systems.

Fire-resistant fluids can be classified into three categories: water-based, oil-in-water emulsions, and synthetic fluids. Water-based fluids are the most common and cost-effective option.

They provide excellent fire resistance but have limited lubricating properties. Oil-in-water emulsions offer better lubrication but have a shorter lifespan. Synthetic fluids offer the best overall performance but are more expensive.

High-Viscosity Hydraulic Fluids

High-viscosity hydraulic fluids are used in applications that require extra lubrication and protection against wear and tear. These fluids have a higher resistance to flow, making them suitable for heavy-duty hydraulic systems that operate under high pressures and loads.

High-viscosity fluids provide better film strength and can withstand extreme operating conditions. They are commonly used in industrial machinery and equipment that require extra protection, such as hydraulic presses and heavy construction equipment.

Low-Viscosity Hydraulic Fluids

On the other end of the viscosity spectrum, low-viscosity hydraulic fluids are used in applications that require quick response and efficient energy transfer. These fluids have a lower resistance to flow, allowing for faster operation and reduced energy consumption.

Low-viscosity fluids are typically used in hydraulic systems that require high-speed performance, such as automotive power steering systems and precision hydraulic control systems.

Wrapping it Up

Choosing the suitable hydraulic fluid for your application is necessary to ensure the optimal performance and longevity of your hydraulic system. The different types of hydraulic fluids offer specific advantages and disadvantages depending on the operating conditions and requirements of your machinery.

Whether you need a mineral oil-based fluid for general applications or a fire-resistant synthetic fluid for high-risk environments, understanding the various options available can help you make an informed decision. Consult with a hydraulic expert or manufacturer to determine the most suitable hydraulic fluid for your specific needs.

Our New Website

We are happy to announce the launch of the new website for Duff-Norton Air Motor Jacks!

The Duff Norton air jack line was first manufactured in 1929, and remains one of the most reliable lifting units on the market. The design has changed only subtly over the years, primarily to improve safety features and accessibility. In 2007, the air jack division was purchased and relocated from Charlotte, NC to Billings, MT. Over the near-decade since the company was relocated, the company has continued to make advances in the safety and reliability of the established products, as well as continue research and development to fit the customers’ specific needs.

The company now manufactures the bulk of their own parts in-house, providing their customers with the best lead times on parts and manufactured components. All of our qualified people pull together to insure the customer receives quality products with exceptional delivery times.
