When it comes to keeping the hydraulic cylinder and other components of your hydraulic system functioning properly, the right fluid can make all the difference. While using the “wrong” fluid won’t necessarily lead to a hydraulic cylinder or gasket failure, it can diminish their overall performance and shorten their life spans. Here are the factors you should look at to determine which fluid is best for your needs.

Viscosity

Viscosity should always be the first attribute you check when determining which fluid you need. Different pump designs—vane, piston, and gear—all have different fluid requirements because of their unique temperature ranges during operation. Adhering to these requirements is essential; even the highest quality hydraulic fluid won’t deliver consistent performance if it’s the wrong viscosity for your system.

Carefully examine the pump’s operating requirements, which will list the system’s lowest cold start temperature as well as its maximum operating temperature. Pump systems will also list their optimal viscosity range. Systems that operate in a wide range of temperatures will likely benefit from a multigrade synthetic oil.

Oil Additives

Hydraulic fluid additives can also improve the performance of the hydraulic cylinder and other components. For example, many fluids use anti-wear additives for better lubrication. Other fluids use detergent oils to emulsify water and disperse contaminants to prevent sludge and deposit buildup. 

Selecting hydraulic fluid with such additives will improve the efficiency of your equipment and extend its usage. When combined with proper maintenance of the system, this will help you avoid unnecessary repairs.

In addition to the right fluid, you need quality parts for your hydraulic system.
