How are hand pumps operated in a hydraulic system?

Hand pumps in a hydraulic system are operated manually. This means that the operator physically engages the pump using their hands to create hydraulic pressure by moving a handle or lever. This manual operation allows the user to control the flow and pressure of the hydraulic fluid based on the specific needs at that moment.

The function of a hand pump is to produce the required hydraulic pressure without relying on an external power source or automatic systems. This can be particularly useful in situations where precise control is required, or in circumstances where power may not be available. Additionally, manual operation of hand pumps is often simpler and more straightforward compared to electronic controls, which could introduce more complexity into the system.

In hydraulic systems, other options like automatic operation, electronic controls, or pedal mechanisms refer to different methods of operation but do not apply to the specific function of a hand pump, which is inherently designed for manual use.
