Cleaner Oil, Smoother Operation

Hydraulic Oil is the energy transfer medium in all hydraulic systems. However, the job of hydraulic fluid goes beyond simple transmission of power. Although transmitting hydraulic energy is the core purpose of hydraulic fluid, it is useful in four secondary functions – heat transfer, Contamination removal, Sealing and lubrication.

Cleaner Oil, Smoother Operation

Hydraulic Oil is the energy transfer medium in all hydraulic systems. However, the job of hydraulic fluid goes beyond simple transmission of power. Although transmitting hydraulic energy is the core purpose of hydraulic fluid, it is useful in four secondary functions – heat transfer, Contamination removal, Sealing and lubrication.

Hydraulic machines produce a lot of excess heat in normal operation often caused by inefficiencies of the components themselves like pumps and motors. Without a way to carry heat away from these components they could easily overheat with resulting damage of seals and internal components, especially as a result of low local viscosity. As oil returns to the reservoir it often passes through a cooler to help maintain optimal temperature range before it is pumped back out to the system. Conversely, hydraulic fluid can carry heat into a system during cold starts when needed.
