Product Selection Differences for Synthetic Hydraulic Fluids

When selecting synthetic hydraulic fluids, there are several key differences to consider, including:

1. Base Oil Type: Synthetic hydraulic fluids can be formulated using different base oil types such as polyalphaolefins (PAO), esters, and polyalkylene glycols (PAG). Each type offers different performance characteristics such as thermal stability, oxidation resistance, and compatibility with seals and elastomers.

2. Viscosity Grade: The viscosity grade of the hydraulic fluid should match the operating temperature and system requirements to ensure proper lubrication and hydraulic system performance.

3. Additive Package: Different synthetic hydraulic fluids may contain various additives to enhance properties such as anti-wear protection, rust and corrosion inhibition, foam suppression, and thermal stability.

4. Compatibility: Ensure that the selected synthetic hydraulic fluid is compatible with the materials used in the hydraulic system, including seals, hoses, and components, to prevent damage and ensure proper performance.

5. Environmental Considerations: Some synthetic hydraulic fluids are formulated to be environmentally friendly, biodegradable, and non-toxic, which may be a consideration depending on the application and regulatory requirements.

6. Performance Requirements: Consider the specific performance requirements of the hydraulic system, such as operating temperatures, pressure levels, and duty cycles, to select a synthetic fluid that can meet these demands effectively.

7. Cost: Evaluate the overall cost of the synthetic hydraulic fluid, including initial purchase price, potential energy savings due to improved efficiency, and maintenance costs associated with fluid longevity and system protection.

By considering these key differences, you can select the most suitable synthetic hydraulic fluid for your specific application and operational needs.
