  • Difference Between Piston and Plunger | Compare the ...

    2021-4-6 · Another application of plungers is in positive displacement pumps. Such as axial piston pumps, for instance. When a plunger moves in the cylinder, a liquid film between the plunger and the inner wall of the cylinder prevents the plunger from getting stuck. It is as if the liquid film supports the plunger just because the plunger is long.

  • Piston Pumps v Plunger Pumps | Pressure Washers |

    As nouns the difference between piston and plunger is that piston is a solid disk or cylinder that fits inside a hollow cylinder, and moves under pressure (as in an engine) or displaces fluid (as in a pump) while plunger is a device that is used to remove blockages from a toilet or sink by suction.

  • Plunger pump vs Piston pump - Difference between

    The most well-known positive displacement pumps are piston or plunger pumps with linear stroke. Their displacement bodies are either discshaped pistons sliding to and fro within a hollow cylinder and having the sealing system attached to their outside diameter, or plungers which slide to and fro within a stuffing box. The motion of the piston/plunger increases and decreases the working volume ...
