New VS motor for my pump

[chrger1970]

Hello All,
I am in need of a new pump for the upcoming season. My old pump was a Hayward Power Max, 1.5hp, single speed. The pool is above ground, 33' round ~33,000 gallons.
I had no problem with the Hayward for quite a few years until it started screaming and just gave up. Ran it maybe 12 hours per day. The line to the pump is 120ac on a 20amp.
I need some help as I know I am getting to the point of analysis paralysis. I would like to put in a vs pump to reduce the costs, electric is insane here, but the vs pumps all seem to be made for inground pools. Can I use an in ground pump?
Another item is that I would like to install a small solar system this spring. This of course raises the question of having enough flow.

Overall, I am happy with a 1.5hp provided it can run the pool and the solar system. I would also love to knock some of those electric costs.

Pray tell, what are your thoughts? Really appreciate it.

Steve

I'm going to just go ahead and change my 1.5 hp single speed motor with a V.S motor. I know my pump is a 56J, so I'm going to buy a V.S motor that will bolt onto my pump. Im looking forward to see if a V.S motor is all the hype.

Make sure you have the correct impeller if you are changing the motor. What VS motor are you using (make/model#)?

I'm going to upgrade to a V.S motor and keep my pump. I'm in the middle of making some changes to my plumbing pad, then in about another month I'm going to get the pump.

I was planning on using this motor. Pureline 1.5 H.P Variable Speed Pool Pump Motor - Round Flange 56J. The impeller is also a 1.5hp. The description of the motor says its compatible.

Charger,

I did the same thing with my Jandy pump years ago and increased from a 1 hp to a 1.5 hp Century VS. Worked great! But it only saves significant $ if you set the pump to run at speed optimized for your pool. I found I could run at ~1800 rpm instead of 3450 for most of the day. This kept the swg flow sensor in active position. Since I was increasing the hp I also increased the impeller size. More peak hp, more peak flow, but power was less than 50% of the old Jandy. If you're running the same hp you may not need a different impeller. I don't see any details in your signature about your equipment but if you want to be able to control speed remotely with almost any automation brand it will help if you use a motor with digital inputs.

Good luck, I hope this is helpful.

Thanks for replying. I have to go out and check out my equipment and make a signature.
