Can I use a ECM27SQU in place of a ECM27CU?
Reply
Unfortunately no because the SQU has a square flange motor face and the CU model has a round motor face. The model of the front pump housing that the motor bolts to will determine the motor that is compatible.

Is this the right motor for it? What other components do I need to buy to do the install?

The variable speed motor replacement is the model ECM27SQU and if you click here you will be directed to the parts diagram for your model pump. Keys 5, 13 and 15 are the most commonly replaced seals with this pump. You will need the pump housing serial number to confirm which shaft seal you will need.

Hi,
I have an old Hayward NorthStar SP4010X20NS I took out of service because a) it was screaming when turned on and b) it was an energy hog and I replaced it with a VS pump. But I have this old NorthStar on my workbench and I am considering the VS motor replacement for use as my water feature pump.
Will this motor fit the NorthStar wet end ok? Any issues with doing so? And before I drop $700 on this project, is a wet-end likely to last forever?
Thanks for any insight.

My Hayward single speed pump motor needs to be replaced. I would like to replace it with a variable motor. Can you please confirm which one is the appropriate motor. I am attaching pictures. Also, please let me know what additional parts I would need for this replacement. Finally, do you have any videos, literature that would be of help to me in doing the work. Thanks.
Hi, P. James. This ECM27CU - V-Green Variable Speed Motor along with the GOKIT2 or GOKIT2SALT are the parts you will need to make the conversion. You can check out our How To Replace the Motor on Your Pool Pump guide.

Hi, Teddy. Yes, the ECM27CU VS motor will fit the Hayward SP2610X15 pump. However, if you're not going to replace your impeller or need the additional HP to match the 2.7 THP of this motor I would recommend the ECM16CU VS motor. I would also recommend getting the Hayward Super Pump Tune Up Kit GOKIT3 or GOKIT3SALT.

Hi
I have a Hayward SP2607X10 with a 1HP motor C48K2N143B1. The motor housing is in bad shape – I can’t decide if I need a replacement motor or motor and pump – the pump appears fine.
I’m clear that I will to move to a variable speed motor for energy saving. I’m not wedded to Hayward. Will switching to a PureLine PL2605 pump provide me with anything different than if I went with the V-Green ECM27CU motor and stayed with the existing pump?
Thanks,
Lee.
Reply
Hello Lee, For a brand new SP2607X10 it would be 419.00, now for the motor would be 129.99, then the seal kit would be 37.95, and the housing would be 189.99 so if you are looking at all vs the whole pump; I would go with full pump. You would be replacing the motor, seals, housing. Still if the housing is the problem then that is just 189.99.

3 questions, I think: 1) Can this motor replace the AO Smith SK1152? (1.5 HP) I don't see a compatibility list, or I missed it while searching. 2) Can you point all of us to a guide to choosing between the 2.7 and 1.65 HP versions--maybe a GPM rating or something of that sort. 3) Do you carry a pump/motor combo that uses this motor? If it doesn't fit my pump, I think I want this motor anyway. Thanks!
Reply
Hi James, This motor will not replace the SK1152 motor because the SK1152 shaft is keyed. The 2.7 motor has higher total hp and an interface with additional features. We have the PureLine PL2606 and the Jacuzzi 94026140 pumps that uses this motor.

Will this fit a Hayward Northstar pump? Do you have a vs motor that would fit a Hayward Northstar?

No, unfortunately, there are no variable speed motors that we know of that will fit the Hayward Northstar pump. There is a dual-speed motor that will bolt up with that Northstar pump.

We have a Hayward Super II Pump Model# K45N2N104 S/N 8B05, 2hp, 1.55KW, 230 volts, RPM 3450 56J Frame. Can I purchase a ECM27CU for this? It doesn't look like a fit for the round flange. I know it should be the right motor, but I just want to be sure before I purchase it. Can I return it if for some reason it doesn't fit?

Brad, This 2.7 HP Variable Speed Motor Round Flange P/N ECM27CU can replace your current motor. We also recomend getting a Tune Up Kit which consist of the replacement shaft seal, housing gasket, diffuser gasket and housing lid o-ring.

Pros: Quiet, easy to install, energy efficient
Cons: More $ initially
Person I spoke to at INYO was incredibly helpful and knowledgable. Our Haywood pump died, and rather than simply replace it with another low-efficiency pump, we ended up getting this variable-speed pump motor instead. It was "plug and play" with the existing hardware, and was up and running quickly. It is a dramatically better and more efficient pump motor than the basic Haywood, and will likely pay for itself in energy savings in a season or 2.

(3 out of 5 stars) It's Ok

Didn't have this pump a full year and the LCD display went bad. Then I find out that you have to completely pull the motor off the pump and provide a picture of the face of the pump before they will do anything with the warranty. And that even if the motor is fine but the display is bad. The savings I'm getting from this pump is ok but it's not as much as a lot of the online videos boast. I haven't seen anything more than a 15% saving on my electric bill. Not happy about having to pull the motor to take a picture. Then put it back together to wait to see what they do with the warranty. You also have to buy another pump seal if the motor is replaced.

(5 out of 5 stars) Perfect replacement for B129 AO Smith motor with Hayward Super II pump.
Reviewed By: ()
Perfect fit to replace a worn out AO Smith B129 motor (Screaming bearings) with a Hayward Super II pump. Easy to change, powered right up. Love the variable speeds and how quiet the motor is when running at lower RPMs. This is my first experience with a variable speed motor so had to take time to understand all the options and features. Called Inyo Pools to confirm going with 2.7 HP over 1.65 ECM16CU since B129 is 1.5 HP but is actually 1.95 HP with 1.3 service factor.

Easy to install with existing pump housing. Based on current schedule, the estimated power usage is around 23 dollars per month. Which is way lower then my old pump. It's also very quiet and easy to program using the controller.

(5 out of 5 stars) a great choice for me to upgrade my Hayward super 2 pump motor
Reviewed By: ()
Found this one while searching for a new pump----- this is a great solution for anyone with an older pump. I have a hayward super II. I had a 12 year old 2 1/2 hp 2 speed motor that was making noise, leaking and running very hot so it was time to change. I have been looking to upgrade to a VSP to save energy for a long time but they run about 1300 + installation I was planning to do it myself but if you saw the way my pump is plumbed..... it would take a lot of effort and about 3 valve changes (no room to cut pipe) at about $75 each to do it. I found the direct replacement motor ($440) and found this one - it is a drop in replacement motor for about any pump: you have to make sure to order the correct mount square or round but you leave the 'wet end' - the part with the pipes in place and just change out the motor part so it is the same as any other motor change. The up front cost was $200 more but according to the energy calculator I should save that pretty quickly- the draw on the other was 10.2 amps at 220v for a total of about 2400 watts on high (less on low speed) --- running at about 8 hours a day year round, over the years the new one will probably save me quite a bit because we all know electricity does not get cheaper. The challenge was figuring out how to put this in place of my 2 speed pump and would it work with my older controller?- a jandy all-button remote with outdoor power center. I researched for a while and found out that the answer is yes and no -- you cannot control the pump speed with my controller but you can control of and on so the pump speed and run times are controlled with the new pumps on board controller, I just set the indoor controller to 'on' and leave it alone and adjust the speed at the pump itself-- not all that big a deal because how often do you change it anyway? my other concern was freeze control as I live where it does freeze sometimes but that isn't a real big problem because the pump has its own (read the manual online) and even if the indoor controller gets turned off, it will turn on if the temp drops below 39 so that shoudn't be a problem. The other issue I had was the two speed relay in the power center- I left that in place but disconnected the power to it and its relay so the fourth wire (that gave power to the low speed side) is disconnected on both ends for safety. once I figured that out wiring was easy (AS ALWAYS MAKE SURE POWER IS OFF AT THE BREAKER BEFORE TOUCHING ANY OF THAT - COMMON SENSE BUT HEY, TO IMPORTANT NOT TO MENTION). i love that the wires are on top so it is very easy to connect and as soon as I got it all together and turned it on, it worked perfectly with no leaks. --- the perfect solution for energy savings without replacing the whole pump! Another small thing that is not mentioned in any of the instructions is there is a thick rubber piece that I could not figure out what it was for until after I put it all back together ---- it goes on the old pump base under the new motor to support it like a motor mount It was VERY hard to install after the fact so when you open it up and see that piece, look at the old motor frame under the pump and see if there is a place to stick it as the new motor is smaller than the old one and without this support, all the weight would be on the bolts attaching the motor to the pump part- probably not a big deal but I am OCD enough to have to put it in there -- believe me, it was not easy after the motor is installed but done now and no more annoying rattle from the pump so you do kinda need it. The new pump motor is much quieter than the old one but can't speak to energy cost yet as my first bill hasn't come but I expect it to me much lower. This is a great investment if you need a new pump motor but the pump par itself is in good shape so, good luck! Id defiantly consider this one, its a great idea and much cheaper than replacing the entire pump.

Reviewed By: Casey D. from Maryville, TN ()
Pros: Energy saving, easy to install, works with my existing pump.
Cons: Prime feature is nice, but unnecessary if the pump is primed
Replaced my 2HP motor with this, and it has been running strong since. Great pump, and great that it has its own schedule. Only negative thing is the priming period at the beginning, have to have a minimum of 1 minute priming time. I wish there was a button to prime before going to the Run setting. Haven't had the pump long enough to see the energy savings on my bill, but just calculating the differences should definitely save a lot of money!
