    List the four main types of piston pumps.

     

    Define the terms axial and radial.

     

    Identify parts in an axial piston pump and draw a diagram.

     

    Pronounce the term “swash plate” correctly. Have your instructor verify correct pronunciation.

     

    Describe how an axial piston pump executes the phases of a positive displacement pump.

     

    Describe how a variable displacement axial piston pump works.

     

    Identify which swash plate positions produce max/min flow rate.

     

    Describe a bent axis piston pump.

     

    Describe a radial piston pump.

     

    Describe a rotating cam radial piston pump.

     

    Take apart a piston pump. Identity internal components.
    Find the data sheet for a piston pump. Identify displacement, drive speed range, viscosity range, fluid cleanliness requirements, and other pertinent specifications. Explain flow rate as a function of pressure, flow rate as a function of drive speed, input power requirements as a function of pressure, case drain flow as a function of pressure, and other pertinent charts.
