Hey Guys
I want to how can we create pump performance curve according to actual site data?

RE: Pump performance curve
System curve is calculated from a model of the piping.

RE: Pump performance curve
Of course the real question is, what are you trying to establish and why?
Are you trying to compare it to the manufacturers data (performance curve) establish a bench-mark for further information or does it sounds like a good idea to try and do it?
It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: Pump performance curve
What you could do is:
- measure flow with a magnetic or ultrasound flowmeter
- measure pressure-gain up and downstream of pump. Problem here you want to have some feet of straight pipe, but no strainers etc. included. this may be hard to fin in a field installation.
- change pressure gain and flow by throttling with a valve and plot a curve.
Alternatively, write down the model# of the pump and google for the curve. Keep in min they come with different impellers.
