Anyone use madimack pumps?

[CptWhiskey]

I currently have a 1.5hp pentair SuperFlo pump that's about 3 years old that came with my pool. It works just fine, but I've always felt it was a bit overkill for my 33k litre pool (12x24, 7' deep end). Also being single speed, I feel like it's not terribly efficient.

I was looking at replacing it with a variable speed pump, and my searches led me to the madimack inverflow eco F300 vs (it's a 1hp). Price seems very reasonable at 740$ cad, and the odd reviews I've come across are all positive.

With a flow rate of 79gpm, if I'm doing this right, then running at 30%, it will do a full turn over of my water in a little over 5 hours and use a fraction of the energy of my current pump.

But before I pull the trigger, I wanted to know if anyone had any experience with this pump, or madimack as a brand overall.

Thanks for any input!

Bfore you go any further if and when you switch to vs pump you must get a larger hp then what you have to be efficient. You can go with even a 3 hp and only use a fraction of the hp and be extremely effective and efficient.

Could you help me understand the logic in going with more HP? I'll explain how I arrived at my conclusion that the 1hp pump would be more than enough, and maybe you could explain the fault in my thinking? I'm still learning....

I read that to properly size a pump for your pool, you take the pump's gpm and how many hours per day you'd like to run the pump. Then if it was sufficient to turn over the water in your pool at least once per day, you were good.

So with my pool at about 8700 gallons, using the the madimack pump at full speed (92gpm),it should cycle my whole pool in about 94 minutes. So then If I throttled the pump to 30% (92 - 70% = 27.6gpm) it should cycle the pool in about 315 minutes (5.25 hours). So I then made the assumption that for my heater, swg and skimmer to keep up, I'd probably want to run the pump somewhere in the 10-15 hours per day ballpark... So 2-3 complete water cycles. This led me to believe that the smaller 1hp pump operating at 30% is more than enough for my pool.

I would greatly appreciate your insight into why you feel that I should instead go to a 2 or 3 hp pump.

Thank you ;-)

I do not see where it says "Listed" by an NRTL (UL or equivalent testing laboratory).

UL Listing required?

When replacing a light fixture that is in a wet niche, is the new fixture required to be UL Listed? I'm considering a fixture from sunseeker, but it is not UL. I would really like to go with the SS fixture, but don't want to do something wrong.

The only benefit to going to a larger pump is to be quieter.

The efficiency difference is negligible.

A 1 hp, 2 hp or 3 hp pump will use about the same amount of power at the same flow rate below 100 GPM.

If you want to know for sure, you can check the efficiency at different flow rates for different pumps.
