In this video, I have explained everything about the Hydraulic Power Pack Unit (HPU)—its working principle, complete component sizing, and all the required formulas. Each step is covered in a logical sequence with a practical example, making it easy to understand and apply in real-world design.

I have also included how to handle variable flow rate requirements and their calculations. Special focus on how to consider the working pressure of the system, with a detailed explanation of the logic behind it.

This video is structured chapter-wise for clarity and depth, covering each aspect of hydraulic power unit design for mechanical design engineers and professionals in automation or SPM design.
