  • The Advantages & Disadvantages of a Piston

    A piston pump uses the reciprocating motion of a piston rod to move fluid along an axis through a cylinder-shaped chamber. As the piston moves through the cylinder, pressure builds up and forces the fluid through the pump. The fluid flowing through the pump pulsates due to the movement of the piston through the cylinder.
