Hi, I have an older pump it's a Hayward SP4010 NS. When I went to look at the motor to try and figure out what I could replace it with, I was hoping for a 2 speed that would be more energy efficient instead of having to go the cost of a whole now ECO VS or Max Flo... Then I saw that the motor on it is and Energy Efficient SP1610Z1. Now I am confused on how to find the right one to upgrade/change it to. I have 1400 gallons of water, inground cleaners, no water falls fountains etc... I am just looking to get a new motor that is more efficient and I already have a timer... Any help would be great!

That's a B128, a 1hp 1.4 service factor. Just look for a 2-speed motor that matches it on the high speed and the frame size.

You also need to make sure that it's currently hooked up for 230 volts.
 
Re: Interesting combination, looking for help on what pump m

I had the exact same pump. I downsized the impeller to a 1/2 HP and put a 1 URHP SuperPump motor on it. The 1 HP Northstar is a BIG pump despite it's HP rating. You might consider downsizing the impeller too.

Shoot, using my phone, sorry for the typo's! Davr would you be so kind as to offer up a model number. You are much smarter then anyone on any sites. They are clueless.
 
Re: Interesting combination, looking for help on what pump m

Hello,
I noticed in your signature you state a 1040ns pump. I think it's a 4010NS (typo) as stated in the first post.
Here's the link to the owners manual: http://www.hayward-pool.com/pdf/manuals/NorthStar.pdf

Page 12 list the impeller and motor numbers. You an do a Google search and fine pricing and cross reference the motor.
Here the 3/4 hp info:
Impeller: SPX4007CKIT http://www.mypoolyard.com/product_info. ... 2db3b1f649

Motor: SPX1607Z1BNS https://www.google.com/shopping/product ... PADEKYrMAE

I'd recommend getting a 2-speed motor. I think this one would work: http://www.yourpoolhq.com/pump-motor-2- ... -b977.html

or

I didn't see the 1/2 hp impeller kit that Mark mentioned.

If you decide to just change out the motor make sure to also order a new shaft seal.
 
Re: Interesting combination, looking for help on what pump m

Thank you. Do you think it's necessary for me to get a 1.5 horse power though. I think my pump is overkill for my pool and I would save more money if I bought a smaller one wouldn't I. I mean in Electricity...???
 
Re: Interesting combination, looking for help on what pump m

You can probably get a 1hp 2-speed c-face that will work. The impeller is matched to the motor size. You have a 1hp impeller so you need a 1hp motor. You can go bigger but never smaller. Think of it as you can but an 8 cyl into a Yugo, but you cant put a 4 cylinder into a big Cadillac.
With 1.5 hp you'll mostly (90% of the time run in low) and that's where you'll get your savings. That and adjust your pump time down.
Mark is the expert in pumps/plumbing stuff.
 
Re: Interesting combination, looking for help on what pump m

Thanks, Mark if you read this... Is it hard to get a different impeller installed and cost wise Will I save more electricity this way? I tried to search for the pump number and couldn't find it.. Is it a Hayward?

1/2 HP Impellers are hard to find but you want to search for a SPX4005CKIT - With this impeller you would use a B971 two speed motor or equivalent.

3/4 HP Impellers are easier to find and you can search for SPX4007CKIT - With this impeller you would use a B973 two speed motor or equivalent.

http://www.poolsupplyunlimited.com/b973 ... 5v/59785p1

But you might want to search around for better pricing.
 
Re: Interesting combination, looking for help on what pump m

THANKS SO MUCH Mark, one last question, well two actually, ids this big enough for my pool and how much do you think I can save a month? One more, I have a standard timer, is it easy to make this work with it?
 
Re: Interesting combination, looking for help on what pump m

Looking at your sig I noticed that you have an in-floor cleaner and that could be an issue. In-floors are a lot like spas in that they usually require high flow rates and pressure so I at this point I would not recommend downsizing the impeller. You may just want to go with a two speed motor just to be safe. The following motor would work with your current impeller.

http://www.poolpartsonline.com/p-8212-b ... -115v.aspx

Running on low speed (without the in-floor) will save about 50% on energy costs. You would still have to run on full speed to get the same cleaning power you get now.
 
Re: Interesting combination, looking for help on what pump m

Shoot, it's a lot cheaper to buy the other motor and with the savings of the electricity it makes a lot more sense. I only have 1400 gal of water... It seems that even with the in floor cleaners it is over kill with the pump that is in there now. That is why I thought if I bought a 3/4 even and ran it for an hour or so on the high speed then the rest on the low it would work.. You seem to be the expert though. Maybe you'll give me another answer based on how big the pool it???

Although, I just looked at that link, it's not too expensive. So maybe I can just run it about 3 hrs on high and then I can run during the day while in the pool for more time on the lower setting. One thing I read was that at the high setting it is hard on your other parts and also it doesn't clean the little things out of the pool, like bugs. I swim around with a net in my hand most of the time to scoop out the bugs, they drive me crazy. Thanks again for all of your help. I imagine I can find a DIY guide to figure out how to get my timer to start the pump in the 2nd speed??

Is this the same voltage, pipe size all of that???
 
Re: Interesting combination, looking for help on what pump m

It isn't the size of the pool but the in-floor system. They are designed for a specific sized pump. If you reduce the size of the pump, the cleaners may not work as well. You could chance it but it really isn't worth it. Most of the savings comes from operating on low speed rather than the reduction in HP.

As for the timer, you really need a two speed timer. They can be added to a regular timer.

Where did you read that? High speed is better for cleaning in general and it really isn't hard on anything except maybe for the filter but only if it is undersized which it is.

Your old pump could have been wired for 230v or 115v so find out which it is and then you can choose the motor.
 
Re: Interesting combination, looking for help on what pump m

A single speed motor is dual voltage can be connected in either 230v or 115v mode. It depends on how it is installed.
 
Re: Interesting combination, looking for help on what pump m

On my setup, I manually added a hi/low switch. My pump setup doesn't have any issues priming on low speed so that's where I tend to keep it. I only use hi to purge the air out of the SWCG cell. Since you have an built in cleaner you may want to look at the EZ2speed motors. They have the timer built in. Are pretty reasonable prices for two speeds with the timer built in. The only come in 230V.
I wrote about them earlier here's the link:
great-find-2ez-speed-75hp-square-flange-2-speed-300-t42909.html?hilit=two%20speed

Link for 1hp: https://www.americanbestpoolsupply.com/ ... 129180.htm
Link for 1.5hp: https://www.americanbestpoolsupply.com/ ... 129181.htm

2EZ manual: http://www.usmotors.com/Our-Products/~/ ... nSRVS.ashx

If you're set up for 230V this might be the cheaper way to go since the timer is built in to go from hi/low and you can customize the run schedule. Your savings will really be made when running on low.

I have no direct experience with the 2EZ motors, but considered them when adding a 2-speed to my system, but my wiring was 115V and didn't want the hassle of converting to 230V.

If you're set up for 115V and looking for an automated hi/low setup I like the Intermatic PE153 Series of timers. Very nice. More expensive than 2 mechanical timers, but does all the functions in 1 box (on/off, hi/low).
