In the market, there are plenty of options when it comes to lubricant selection. Generally, the operators will purchase specific hydraulic oil from their machine manufacturer or machine manual. But how do you know if you're using the right hydraulic oil? Most lubricant mis-specifications don't lead to sudden and catastrophic failure, but rather they shorten the average life of the lubricated components.

When selecting a hydraulic fluid, it is very critical to determine the system's needs: viscosity, additives, operation, etc. which in order to ensure the system's ability to function properly and attain long life. Viscosity is of paramount importance in choosing a fluid. These specifications are typically determined by the type of hydraulic pump employed in the system, operating temperature and the system's operating pressure.

With hydraulics, there are three grades for considerations - ISO 32, ISO 46, ISO-68. These specifications are typically determined by the weight and viscosity of the oil. Type of fluid is best for a particular equipment Data Sheet to show how to select the right hydraulic oil for your machinery.

When selecting the appropriate viscosity grade, look for the optimum viscosity required by the hydraulic pump. Check the operating temperature of the pump and see if it falls between the temperature ranges of the lubricant in question. If not, you may need to increase or decrease the viscosity of the lubricant to achieve the desired, optimum viscosity.

If you use oil with a viscosity that’s too high for the climate in which the machine must operate, the oil won't flow properly or lubricate adequately during cold start. If you use oil with a viscosity too low for the prevailing climate, it won’t maintain the required minimum viscosity, and therefore adequate lubrication, on the hottest days of the year.

As you can see, selecting the proper hydraulic oil for the application is not a hard task, but it does require time to research the application, determine the resulting cost and decide which fluid type is best. Just because a machine will run with a particular product doesn't mean that product is optimum for the application.
