  • Hydraulic Pressure vs. Flow: Understanding the Difference

    Pressure is the result of resistance to flow. In our training classes, we use the simple schematic shown above to explain this concept. A fixed-displacement pump is the simplest type of hydraulic pump. It is turned by a primary mover, generally an electric drive motor or, in mobile equipment, the same engine that moves the machine.
