The high amps/horsepower were seen with two sets of internals. The first set was the conversion which comprised of a new inducer, diffuser, diffuser cover, and impeller. The impeller was machined to the diameter required for the conversion and installed. When the shop tried to generate the...
We measured the power with a power condition monitor. I'm not sure of the details, but it measured voltage, power factor, and current through the 480V 3ph motor starter. It is a 125 hp motor. With that, the power was calculated and given to me.
As for the skim cut on the diffuser cover...
I'm having problems with a LMV-311 drawing more power than the predicted performance curve says it should. At our current flowrate, we're reading a motor load approximately 15-20 hp above where the pump curve says it should be.
We are still within the limits of this motor, but with a pump...
