    Question

    What is the primary mechanism by which a hydraulic pump moves fluid?

    A.

    By generating an electric charge to attract the fluid

    B.

    By using thermal expansion of the fluid

    C.

    By creating a vacuum to draw fluid in and then pressurising it

    D.

    By using gravity to push the fluid through the system


    Correct option is C

    A hydraulic pump works by creating a low-pressure (vacuum) region at the inlet to draw fluid in, and then mechanically pressurising the fluid to move it through the hydraulic system.
