we have two main kinds of hydraulic systems
1- open center
2- closed center
open center consist of gear pump (continuasly work) to give lower prissure which easier to do the maintenance and more cheaper and higer in feul consumption
the closed center with piston pump . work when you need the pressure . and give higher pressure and less in fuel consumption . but more expensive and harder to make maintenance
