Keep blowing pump motors pool guy says call electrician

Re the smaller valve causing a current increase, all other things being equal, it normally works the other way. In a broad part of most pumps' performance curves, power needed varies with flow rate. Adding a restriction reduces flow, so current goes down. For example my VSP reports a small fall off in watts being used as the filter gets dirty and flow rate fades a few gpm (I have a gauge). After cleaning, both jump back up.
 
You have a WF-26 pump which says 1.5 HP on the label, but the impeller chart shows 1 hp and a 073128 impeller.

Motor makers make two identical motors and label one as 1 hp with a 1.65 service factor and the other as 1.5 with a 1.1 SF. Both have 1.65 total hp.

Then, pump makers do the same thing with pumps. They make a full rated pump and a max rated pump that are identical.

So, a 1 HP full rated pump and a 1.5 max rated pump are the same pump with different horsepower ratings and neither rating is actually correct because the correct rating is 1.65 hp.

There is also a 1.5 hp full rated pump that needs 2.2 hp.

So, you have two different pumps that are labeled as 1.5 hp pumps that take different total horsepower motors.

This is why so many people get confused.

Yes that IS confusing. I had the “rebuild” guy bring me all new parts AND move us to factory model impeller. Below is the pump body and the motor that now allegedly has the factory impeller 128 ( he installed without letting me know). Do I now have “other” mismatches that could cause the 8.6 reading? Which model shaft seal do I need for this motor? Is there a heavy duty shaft seal for salt pools? Thank youIMG_0882.jpeg

Did the whole front end get replaced?

Yes I felt that the original refurb was shot due to running for days at 12.5 Amps so requested he start over with all different parts so it’s a new to me front end and motor. I have requested the diffuser part number bet that too is aftermarket.

I doubt he realizes how detailed this gets and has been lucky that the pumps he replaces hold up just long enough that it seems he is doing it right. I think this one would run for awhile if I left it at 8.6 amps. I’m thinking of purchasing the right diffuser and seeing what happens. I did order the smaller impeller but maybe it will not be required. Thanks James!

Maybe just get a new variable speed pump and stop rebuilding this pump.

You are putting too much time, effort and money into this old pump.

A variable speed pump can reduce your power usage from about 2,000 watts to about 200 watts.

It sure turned into a rabbit hole I never expected. Thank you for trying James!
