Electrical Engineer helping figure out voltage drops

Hey everyone, I'm upgrading my fountain pump and today I pulled out the old pump and noticed that its a 230V pump thats been hooked up to 120V.

Here is the pump and full specs

If the pump is capable of pulling 160PM (when its hooked up to 230V) Can anyone figure out roughly the GPM the pump would pull at the 120V I was using it at? As this would help me figure out the correct size fountain pump I would need.

Why are you sure you have 120v? The pump shouldn't have run if only 120v.

Yes, absolutely certain. Its definitely only 120V

No electrical engineer needed here.

It shouldn't have been running at all on 240v.
There wouldn't be any way to figure any type of GPM with it running on 120v.

You could discharge the pump into a known size container..... like a garbage pail..... and see how many seconds it takes to fill. Then calculate minutes from there.

Centrifugal pump output is not linear so testing it is about the only way to know. But, that was a low volume pump. It will be easy to find a pump in that size range. Then if it's not the flow you want install a valve on the outlet to either restrict the output or dump some of the output to get the desired flow.
