In a two stage pump; if the head required can be adequately supplied by one impeller, which impeller should be removed?

RE: Removal of Impeller
thoughts . . .
1) may have rotor imbalance/stability without 2nd stage impeller . . .
2) 1st stage may be design for low npsh - insufficient details provided.
3) you will likely be better off with pump suited for process conditions; than bastardizing existing pump.
frankly, i'd consult with OEM and obtain there opinion or expertise on the matter.
regardless, good luck!

However, I would check with the manufacturer or agent for their advice on this.

RE: Removal of Impeller
When you remove either ist or 2nd stage, which curve do you follow? How do you know one stage is enough?
Or you may think to trim the impellers -- at least you have a curve to follow. -- or replace the pump with a single stage one.
