Water Thanks

Did the flow testing. Unfortunatelly could not measure individual flow for each pump, rather each combination of three pumps. I may not be clear all along but I do know that the pumps are performing well bellow their designed curve. What I am trying to figure out is why?

Thanks for your interest again
Paul Maier 1st step is do a field test to compare pump field performance of each pump to the manufacturer's curve. Simply because a pump has been refurbished/rebuilt doesn't mean that performance would automatically return to original specifications, (just like a car there are good engine rebuilds and not so good rebuilds).

Run each pump individually and measure Flow, Discharge psi, Suction psi, rpm, and kW (if available) for 5 points on each pump. Plot the field data and compare to manufacturer's pump curve. I suspect you will find performnace significantly below manufacturers specs. If you can measure field kW you will be able to calculate pump efficiency for each of the 5 test points as well.

Then I suggest you read the article in the November 2008 issue of P&S entitled "Pump Refurbishment & Coaitngs"


Good Luck
