Environmentally Sustainable Hydraulic Fluids: The 3 Best Replacements

Hydraulic fluids are essential for the proper functioning of hydraulic systems. These fluids transfer power and lubricate the internal parts of the system, ensuring that it operates smoothly and efficiently. However, choosing the right hydraulic fluid for a particular application can be a daunting task. With so many different specs and brands available on the market, it can be confusing to determine which fluid will be the best fit.

Thankfully, we offer a range of hydraulic fluids that are designed to meet the needs of various industries and applications. These fluids are made from renewable, biodegradable materials, making them a sustainable and safe alternative to traditional petroleum-based fluids.

The first thing to consider when choosing a hydraulic fluid is the system's operating temperature range. The fluid must be able to operate effectively at the system's lowest and highest temperatures. If the fluid is too thick, it will not flow correctly, causing the system to become sluggish. On the other hand, if the fluid is too thin, it may not provide adequate lubrication, leading to excessive wear and tear on the system's internal components.

Renewable Lubricants' hydraulic fluids are specially formulated to perform in a wide range of temperatures, making them suitable for use in both hot and cold climates. Our hydraulic fluids have a low pour point, which means they remain fluid even at very low temperatures. Additionally, they have a high viscosity index, ensuring that they maintain their viscosity at high temperatures.

Another critical factor to consider is the type of hydraulic system you have. Different systems have different requirements when it comes to hydraulic fluids. For example, some systems require anti-wear additives to prevent excessive wear and tear on the system's internal components, while others require anti-corrosion additives to protect against rust and corrosion.

We produce hydraulic fluids with various additives to meet the specific needs of different hydraulic systems. These hydraulic fluids contain anti-wear additives, anti-corrosion additives, and anti-foaming agents, ensuring that your system runs smoothly and efficiently.

Lastly, consider the environmental impact of the hydraulic fluid you choose. Traditional petroleum-based fluids can have a significant impact on the environment, as they are not biodegradable and can contaminate soil and water if leaked or spilled. Our hydraulic fluids are made from renewable, biodegradable materials, making them a sustainable and safe alternative to traditional fluids.

Choosing the right hydraulic fluid for your application doesn't have to be a complicated process. By considering the operating temperature range, the type of system, and the environmental impact, you can narrow down the options and select a hydraulic fluid that will keep your system running smoothly while also minimizing its impact on the environment. Renewable Lubricants' range of environmentally friendly hydraulic fluids is an excellent choice for anyone looking for a sustainable and safe alternative to traditional petroleum-based fluids.

This is not our full line of hydraulic fluids but our best-selling traditional hydraulic fluids. RLI also offers more specialized fluids such as: Dielectric, Food Grade, HEES, Fire Resistant, Tractor/Trans (UTF) and HEPR hydraulic fluids. When buying hydraulic fluids, RLI recommends looking at the OEM spec.
