# What are characteristic values for a piston pump?

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?

(example of a type of piston pump source)

• Are you looking for other ways to identify or classify the pumps? – Trevor Archibald Jan 23 '15 at 21:14
• 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). – John H. K. Jan 23 '15 at 21:17
