Product Description


Versatility and performance best describe A. O. Smith's new V-Green™ variable speed pump motor with integrated timer. Capable of delivering superior energy savings of over 80% versus a standard single-speed motor, V-Green motors are well suited for pump applications ranging from 3/4 - 2.7 total horsepower (THP). Spurred by consumer interest in energy-saving products and government-mandated efficiency standards, the innovative V-Green variable speed ECM offers premium efficiency boosted by such features as Power Factor Correction, which raises overall efficiency while reducing input amps! The state-of-art user interface ensures programming ease and flexibility, with on-screen navigation, ergonomic selector switch, and pre-set programs for out-of-the-box operation. A. O. Smith's V-Green is Title 20** compliant and with three user-defined variable speeds is a superb choice for reducing energy consumption, for lowering overall pool ownership costs, and for satisfying regulatory requirements.

Round Flange Hayward Super Pump, Super II Pump & Max-Flo Pumps

** California's Title 20 legislation states that pumps > 1HP (total) must be 2-speed or variable speed, and must have a control to default to low speed (i.e. timer)

Want to take your V-Green Motor to the Next Level?  Consider the VLink™ (allows you to easily monitor and manage energy consumption and optimize your pool pump settings from a mobile device).

Will this motor work on a 3 hp super pump ll SP3025X30LZ

A  Answered on 10/14/2019 by InyoPools Product Specialist Steve M.

John, yes, the V-Green 2.7 HP Round Flange 56J Variable Speed Motor - ECM27CU would work as a variable speed replacement motor for your SP3025X30LZ pump.  

?     Asked on 10/11/2019 by John Smith

Does th ECM27CU come with a base

A  Answered on 10/14/2019 by InyoPools Product Specialist Steve M.

John, no, the V-Green 2.7 HP Round Flange 56J Variable Speed Motor - ECM27CU does not come with a base. As long as the FR is the same as your old motor the ECM27CU should fit your existing base.

I have a Hayward Super Pump 2610x15. I believe this exact variable speed motor will work with my pump. My question is...do I need to do any upgrades to the diffuser or impeller being that my pump is 1.5hp and this one here is capable of up to 2.7hp?

A  Answered on 9/13/2019 by InyoPools Product Specialist Hector F.

You would need to change the impeller and diffuser if you are trying to get the full strength capacity out of the motor however that is a significant increase so more than likely you will not need that. 

?     Asked on 8/13/2019 by Jeff

My energy company offers a discount for replacing single speed with variable. They said I can replace just the motor with an Energy Star certified motor on my existing pump. Is this motor Energy Star certified?

A  Answered on 8/13/2019 by InyoPools Product Specialist Lennox H.

Hi, Jeff. Variable Speed Motors only do not qualify for any energy company rebates, ONLY complete pumps. 

?     Asked on 8/7/2019 by Ron

Will this motor match up with an older Jandy VS FloPro 2hp?

A  Answered on 8/7/2019 by InyoPools Product Specialist Lennox H.

Hi, Ron, It will NOT, you will need the V-Green 2.7 HP Square Flange 48Y Variable Speed Motor - ECM27SQU.

Is it possible to turn the control panel around to face the opposite direction? It looks like only 4 bolts attach it. Thanks!

A  Answered on 8/7/2019 by InyoPools Product Specialist Lennox H.

Hi, Barton. The interface cannot be rotated. 

?     Asked on 8/7/2019 by David

Hi I have a Hayward dual speed 2.5HP (SP3020X252AZ) and is looking to upgrade to a variable speed. Is this the right model & if there are other parts that I need to get? Please also recommend a higher HP with variable speed (3HP + parts). Thank you!

A  Answered on 8/7/2019 by InyoPools Product Specialist Lennox H.

Hi, David. This ECM27CU along with the Super II Pump Tune Up Kit - GOKIT2 or GOKIT2SALT are the parts you'll need. There is not an option with higher horsepower.

I have a Jandy JHPU2.5 HP single speed pump for a 1.9k Gallon pool + Spa + Cleaner+Pentair 60 DE filter, and the piping is 2". I was told the 2.5 HP is too big for my use, with the SWG system. Can I use this motor as replacement or should I consider the 1.6 HP VS V-green? I also have a Zodiac Aqualink RS8 automation. Can this motor with the automation system?

A  Answered on 7/23/2019 by InyoPools Product Specialist Hector F.

Yes, this motor would be suitable replacement for your application and in order for this motor to communicate with your automation you would need part number 2517501-001.

?     Asked on 6/12/2019 by Michael Reynolds

I need to replace an A.O. Smith RS1500 motor. I've seen from other questions that this will work. But is it worth 3 times the price in energy savings? And how hard is this ti wire in? Will I need an electrician or can I just replace motors and re-hook up the wires? Thanks for your help.

A  Answered on 6/12/2019 by InyoPools Product Specialist Lennox H.

Hi, Michael. To determine if the variable speed pump is worth the cost, you will have to calculate the Total Dynamic Head (TDH) of your pool. An electrian is not needed if you know what you're doing. You can use our How To Wire A Pool Pump guide for directions. 

?     Asked on 5/22/2019 by Joe

Can I use a ECM27SQU in place of a ECM27CU?

A  Answered on 5/22/2019 by InyoPools Product Specialist Hector F.

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.

I have a Jandy Stealth Pro SHPF2.0 Is this the right motor for it? What other components do I need to buy to do the install?

A  Answered on 4/2/2019 by InyoPools Product Specialist Hector F.

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.

A  Answered on 3/30/2019 by InyoPools Product Specialist Lennox H.

Hi, DJ. This motor will not fit the NorthStar pump housing due to the drive and the locking ring. Pump housings will not last forever. You may want to consider the Hayward TriStar VS Pump - SP3202VSP

?     Asked on 3/12/2019 by P. James

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.


A  Answered on 3/13/2019 by InyoPools Product Specialist Lennox H.

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.

Hello, I have a Hayward Super II K48N2N104 (SP-1620-Z1-BE) pump and looking to replace with variable speed. I see where you recommend the ECM16CU and also the ECM27CU. Mine is 2hp, is the 1.6 sufficient or do I need to go to 2.7?

A  Answered on 12/27/2018 by InyoPools Product Specialist Lennox H.

Hi, Dave. This ECM27CU is the correct variable speed replacement option. You will also need to get the Super II Pump Tune Up Kit - GOKIT2 or GOKIT2SALT.

A  Answered on 4/24/2019 by Product Owner

Did you end up replacing the Super II (SP-1620-Z1-BE) w/ the variable speed 2.7 HP motor - checking what your experience is

A  Answered on 12/27/2018 by InyoPools Product Specialist Lennox H.

Hi, Sanjay. This ECM27CU is the correct motor for your current pump. You will also need to get the Super II Pump Tune Up Kit - GOKIT2 or GOKIT2SALT. You can use the RS-485 Network Connection or purchased the V-Green Automation Adapter Kit - 2517501-001 if you have available relays.

I have a Jandy Stealth Series Model JHP2.0 pump controlled by my Jandy Aqualink RS controller.. Will this motor work on my present Aqualink RS controller or do I have to upgrade my Aqualink RS contoller board for this VSP motor to work. My present controller was installed back in 2005. Thank you.

A  Answered on 9/20/2018 by InyoPools Product Specialist Lennox H.

Hi, Johnny. You will no need to upgrade your Aqualink RS; however, you will need the V-Green Automation Adapter Kit - 2517501-001

Yes, this would be a suitable replacement motor for your model motor. 

?     Asked on 7/30/2018 by Ronnie

what are the program set up requirements for a Goldline control system when you change to a VF drive ECM27CU?

A  Answered on 7/30/2018 by InyoPools Product Specialist Lennox H.

Hi, Ronnie. To use the ECM27CU motor with the Goldline controller, you will need the V-Green Automation Adapter Kit - 2517501-001. For programming and wiring instructions see the V-Green Automation Adapter Kit Manual.  

?     Asked on 5/9/2018 by Travis

Does this motor fit a Jandy JEP 2.0 Pump?

A  Answered on 5/9/2018 by InyoPools Product Specialist Hector F.

No, actually the A.O. Smith variable speed motor that would fit is the ECM27SQU

?     Asked on 4/17/2018 by Vic M.

I have an existing 1.65 THP motor I would like to replace with a variable speed. Should I use the v-green 165 or is their any energy consumption advantage/ disadvantage in using the 270?...thanks, Vic.

A  Answered on 4/19/2018 by InyoPools Product Specialist Lennox H.

Hi, Vic M. The V-Green 270 would be more efficient using the 1.65 impeller. The 270 motor will not reach the max load working amps.

A  Answered on 7/28/2017 by InyoPools Product Specialist Lennox H.

Hi, Mohsin. The Century ECM27CU VS motor can be used to replace the Hayward K48M2N110 motor. I would recommend getting a tune up kit, bit we will need to know the model or name of the pump housing.

A  Answered on 7/26/2017 by InyoPools Product Specialist Lennox H.

I have 1 1/2 single speed hayward super pump (sp2610x15) will this motor fit my pump

A  Answered on 5/2/2017 by InyoPools Product Specialist Lennox H.

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.

Good morning Ali, Yes, This motor will fit. It has the same frame size and the controller will link with your aqua link system.

?     Asked on 1/2/2017 by Lee

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.

A  Answered on 1/3/2017 by InyoPools Product Specialist Stacey M.

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.

?     Asked on 5/24/2016 by James

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!

A  Answered on 5/30/2016 by InyoPools Product Specialist Lennox H.

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.

?     Asked on 5/8/2016 by

A  Answered on 5/10/2016 by InyoPools Product Specialist Charlie R.

A  Answered on 5/15/2015 by InyoPools Product Specialist Lennox H.

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.
