For a piston pump you can calculate/measure things like,

  • Average Volume flow rate (m³/s)
  • Geometric Values (Surface)
  • Pressure over time
  • closing times of the valves
  • energy conversion efficiency $\eta$

besides those, what charateristic values are there?

    $\begingroup$ Are you looking for other ways to identify or classify the pumps? $\endgroup$ Jan 23, 2015 at 21:14
  • $\begingroup$ Im looking for other values beside the described - You can use those to classify a pump, certainly. Or gauge the quality of a pump (in the case of energy conversion efficiency). $\endgroup$

Here are some other criteria:

  • Cycle time
  • Piston speed
  • Piston friction
  • Device lifespan (most likely a function of the number of cycles completed)
  • Number of suction/discharge ports
  • Type of valves used

Hope that helps!

• Piston pump has a wide range of pressure • It can manage force without the moving flow rate. • The Pressure and flow rate variations have a small effect on the pump performance. • It has the capability to move high viscosity fluids such as abrasives and slurries with an excellent design. • Low speed. • The fluid discharge doesn’t depend on the head. Due to this feature, these pumps can be used as metering pumps. • This type of pump has high efficiency
