Resistance to flow creates pressure.
load created or Mechanical action due to inlet creates pressure in the outlet line of hydraulic pumps
About 120 bar rated & (180 - 200 )bar Maximam
In the outlet of pump system creates pressure.
Pumps produce current and resistannce creates pressure
Pressures in the out and in the lines downstream are given by the pumps, particullarly the outlet line is more exposed to the back pressure in the circuit.
Possitive dispacement force create the pressure inthe Outlet line, actually mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line of the pump
The load or actually the resistance of the system including the load
load inlet pressure from the pump
It is the actuator like working hydraulic cylinders or drive motors creates pressure in the outlet of hydraulic pumps.
