Understanding the basic principles of hydraulics and how everything comes together in order to make machines be able to move heavy loads. We can start by understanding Pascal’s law and pressure. See video below.
Gear pump
How does a hydraulic gear pump work? Where is the actual tearing and wearing of the pump and why would you eventually have to change it. By the way, it is always a good idea to maintain clean oil for good preventive maintenance, search for “ISO 4406” in the search bar for maintenance videos.
