At the pressure regulator.
Pressure by the hydraulic pump is made​​.
Hydraulic pump that produces pressure in a hydraulic system. It takes energy to pump the electric motor or engine mechanical.
hydraulic pump
The pump in a hydraulic system forces fluid out and that creates pressure
it is a pump that delivers the same pressure irregardless of load

What is your power hydraulic pump. The pump power is higher the smaller cylinder.
The operation of the pump in a hydraulic jack is to generate pressure. This causes the jack to rise and lift as needed.
Torque hydraulic motors is done by oil pressure and oil pressure is caused by the hydraulic pump. The hydraulic pumps produce higher pressure gets too much torque.
That is a 'statement' - what is the question.
Yes, a hydraulic pump and hand operated controls.
A power source - such as a combustion engine or electric motor - mechanically actuates a pump which pushes hydraulic fluid through it. This maintains pressure in the hydraulic system.
