Super II Pump Replacment Decision

[versstef1]

It all started because I wanted to save money by keeping my existing motor and put it back on when this one burns up... I only really needed a new housing, so that led me thinking it's cheaper to get a new pump and keep the motor. I was trying to think far ahead, but not far enough....

Hi there. I hope I'm not reviving a thread no one cares about, but I thought I should update you, as I received my pump today. A lot of what we discusses was wrong. It turns out Hayward gave me wrong answers, too. Only the Inyo chart I linked (and used to make my hasty purchase decision) was right after all. The pump I received is a SP3010EEAZ. 1 HP, SF 1.5, THP 1.5. The motor model is SP1610Z1BE. Max amps is 14.6/7.3 after all. Now, all the charts and tables say this will give me the same performance as the 1.5HP/1.0SF SP3010X15AZ (motor UST 1152; max amps 18.6/9.3) at a lower amp draw. In theory, wouldn't that save about 25% energy (that's what I thought when I pushed the "buy" button)? Anyway, no matter who I asked except Inyo said max amp draw was identical, and it's not. I'm going to email you pictures of the old and new motor labels. If I could have one more minute of your time, before I have it installed, I would appreciate it if you could confirm that I will be OK using this new pump and also whether I can still put my old motor back on later (if I still choose to do so.) Reason for asking is that there are 3 other numbers different on the label, and I don't know if they mean anything or not. First, the "kW" number is .75 on the new motor, not listed on old, but online found it might be 1.1. Second, the new motor says "CODE L", the old one "CODE H". And third, the new one says "Thermal Protected CET50ABN" and the old one "CET40ABM". Thanks, appreciate it, and hopefully contributed something by sharing the actual label!

Here's the rule I found on the AO Smith site: if the old motor's HP x it's Service Factor (SF) equals OR is less than the NEW motor's HP x SF, you're OK. If the new motor's multiple is LESS than the old motor's, you are NOT OK, and will need to replace the impeller.

Looking at the photos you sent, what I'm seeing is:
OLD => 1.5hp x 1.0 SF = 1.5
NEW => 1.0hp x 1.5 SF = 1.5

So, I think you'll be OK. About any of the other, I'm not sure.
