Using the right type of hydraulic fluid is essential to ensure pumps will effectively function. Hydraulic oil is used for various applications in a hydraulic system and in every single component involved, such as the pumps. Energy transmission, heat dissipation, component lubrication, and corrosion prevention to name a few of the common uses of hydraulic oil. Hence, utilizing the right type of fluid is imperative, and determining which ones are excellent depends on other factors, such as the type of pump, peak operating temperature, the seal material of the pump.
Since the hydraulic pump is the main part of a hydraulic system, using the wrong hydraulic fluid will negatively affect its performance and reduced the life expectancy of your unit. It can lead to gunk formation, excessive heat production, erosion, and low efficiency. In case you notice the abovementioned signs, it indicates the need to switch to a better hydraulic oil that is more suitable for it.
When looking for the right hydraulic fluid consider these key properties: viscosity, thermal properties, lubrication, flammability, stability, and foaming. There are three basic types of hydraulic fluid:
- Water-Based - This type is less used because it is less effective at lubrication compared to other types but it is ideal in cases where a potential fire is a matter of great concern.
- Petroleum-Based - Most commonly used because it is cheaper than other alternatives considering its high-performance properties that can work well in flammable settings.
- Synthetic - Most expensive type but ideal in situations with extreme temperature variations and high pressures.
Pumps as well come in different types thus, require different fluids.
