Energy density:
210 bar (Industry standard)
500 bar
Advantages
- High power density
- Good controllability
- Good timing behaviour due to low inertia
- Simple and reliable protection against overload
- Good energy transmition over medium distances
- Good lubrication and dissipation of the heat loss through the pressure transmission medium
Disadvantages
- High energy consumption
- High weight of drive and control elements
- Losses from friction and internal leakage
- Sensitive to dirt
- Fire hazard
