New Pentair pump replacement

[Genec]

Made the mistake and left my pump out over the winter. Seals and bearings are shot. I was looking to replace my 011773 (WF26) 1.5hp with a newer model.
I have a 30-35k gal pool. I am confused as to whether my pump truly runs at 1 or 1.5hp. Nobody seems to have a 1hp (011059) or 2hp (011060) but there are some 3hp around.
I have seen the 011018 and 011056. Is there a significant difference between those two? And can I use the 3hp but at lower power or is that a waste?
PS dont want to have to repipe.

Welcome to TFP.

011018, 011028 and 011056 pumps are all basically the same. Get whichever one is available.

Running the pump at a lower RPM/HP will save you lots in your electric bill.

Thanks for the response. I assumed the 011018 had some older technology. I'm afraid all this stuff is more to break anyway.
Whichever model do I need to figure out GPMs? How would I figure the "optimal" run speeds etc? Do I need my pool guy to do that?

GPMs depend what your equipment needs.

There is no optimal run speed. It varies based on your pool environment, time of day, weather, season, etc.

Determine Pump Run Time

To figure out how many hours you need to run your pump, you need to know how fast your pump works. You can find this here.

Actually not having a problem just trying to replace my 1.5 hp Whisperflo. I never invested in the Intelliflo because as I said more to break.
However they seem to be phasing out the single speeds. I have a 30-35k free form pool and that 1.5 worked fine for me until I left it outside for the winter...

Get a Pentair Superflo VS pump which will run on 120V. Or a Calimar or Black & Decker VS pump.

Only problem with the Superflo VST is I think I have to repipe it. Wont match up. And not all that much cheaper than the I2
