Going from single speed Hayward Max Flo II (1hpx1.25sf) to INYO VS options- NEED HELP!

[estcstpool]

Hi All like the titles says i currently have a hayward max flo II pump with a 1 hpx 1.25 sf motor (so a 1.25hp). I have about a 15k pool with an IC40 SWC system. The pool pump and SWC are controlled by a mechanical intermatic timer with a panel on the wall. I have put in the SWC myself and have replaced my motor before to the same max flo II motor (i was new to pools so just stuck with what was there).

My motor is starting to go so i was thinking of this INYO variable speed century replacement motor. Its only $389 and has more HP than i have already. Why would I not want to go this route? I know centry motors are good so why would i want to get an entirely new pump for ~850 bucks like a pentair? I currently just set the timer and forget it, i dont see any need for automation, thats why i have a start stop times and from what i can tell the pumps onboard timer will controll the variable speed part........

What else should I be considering here? Would this be a good replacement? Another was one of those chinease pure pulse pumps that inyo sells.

If your current motor is serving your needs as far as HP the century will work well as a replacement. This replacement pump has an internal timer and also controls the speeds. This pump controller most likely needs to be powered at all times so you will need to bypass the timer or leave it on all the time. I have the 270 motor and am very happy with it. The 165 version seems to have a different controller than the 270. The timing is set at a minimum of 2 hour intervals. If you wanted to run a timed event at less than 2 hours you would have to use the manual setting and shut down when needed. You could still use your Intermatic timer to run the SWG but would have to coordinate run times with the pump timer. The 165 controller does not have a clock so you would have to use the three settings to total 24 hours to keep it running the same schedule every day. If you decide to use any variable speed motor with a self contained controller please consider using a surge protector at the breaker panel.
