Product Description

Premium-Efficiency 2-Speed Pool Motor with Integrated Timer

A. O. Smith’s new 2Green two-speed premium efficiency replacement pump motor with integrated timer packs tremendous value into an easy to- nstall package. Energy efficiency continues to drive the needs of the pool market, from legislation to increased awareness of energy costs and environmental impact. And thanks to the 2Green’s energy efficient high and low speed windings paired with an onboard timer interface, energy consumption can be reduced by as much as 58% over single speed motors. The all-in-one integrated motor and timer means less work for an installer and maximum energy savings for pool and spa owners. A. O. Smith’s 2Green is Title 20 compliant** and best of all, there is no additional wiring required for new construction or retrofit installations!

**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)

I have this motor/controller combination but the motor portion is failing (over-current errors on controller display, low speed is very noisy and only runs for few seconds before error appears) As your website says the B2984T is discontinued, can I just buy a replacement motor (B2984) and re-install the controller on the new motor?

A  Answered on 10/15/2019 by InyoPools Product Specialist Michelle B.

Hello, You would have to get a toggle switch or a dual speed timer for the new motor. You will not be able to put the drive on the new motor.

?     Asked on 7/20/2018by Matt

I’ve got a separate digital timer running a single speed motor now. Would this motor and timer function properly if I installed with my existing timer in place and left it in the “on” position? I want to do as little electrical work as possible.

A  Answered on 7/21/2018 by InyoPools Product Specialist Lennox H.

Hi, Matt. Yes, it will. You will have to remove the on/off trippers and leave the timer in the on position so that it constantly supplies the motor with power.

I have an A.O. Smith pool pump model UST1102 and would like to replace it with a comparable two speed pump with a built in timer. What is the new pool pump model?

A  Answered on 7/8/2018 by InyoPools Product Specialist Hector F.

No, the correct replacement dual speed motor would actually be the model B973T

i have a sta-rite dura-glass pump p2ray5g-183l with 2hp century b984 motor. I main electrical switch has 3 positions - hi, off and low. Is this the most energy efficient motor? What else do I need to buy ?

A  Answered on 5/20/2018 by InyoPools Product Specialist Lennox H.

Hi. You can switch to a variable speed motor like the ECM27SQU motor. It will provide you with more operating options and features. You will also need the Sta-Rite Dura-Glas Tune Up Kit - GOKIT54.

I have a ao smith 1.5 hp SQ1152 motor what motor would I need to convert to a 2 speed . could I go up in hp to the b2984T

A  Answered on 4/9/2018 by InyoPools Product Specialist Hector F.

The dual speed motor replacement would be the model SQS1152R. The toggle switch that you may need is listed in the product details or you can use a dual speed timer model number T106R to run off of the main timer. 

?     Asked on 10/24/2017by Mike

I have a Max E Pro 2spd 2.25 hp. The bearings went out and I was wondering if this motor and dig controller would work on my pump system. The system controller is a Hayward dig controller. I didn't see any bearings on your sight for my motor P6RA6YG-207L

A  Answered on 10/25/2017 by InyoPools Product Specialist Lennox H.

Hi, Mike. You will need to provide us with the motor model or part # so that we can locate the bearings. This motor will work with your pump, however, is not compatible with any Hayward Automation Controller. I would recommend staying with the UQS1202R motor as the replacement.  

?     Asked on 9/7/2017by Eric

Does this pump have any type of freeze protection?

A  Answered on 9/8/2017 by InyoPools Product Specialist Lennox H.

Hi, Eric. This motor is not equipped with freeze protection.

I have a Hayward pump connected to a SP3220Z2ME 2-speed motor. The frame size is Y56Y; H.P. is 2.5/.33;single phase; 208-230 volts. Will this motor fit my hayward pump right out of the box?

A  Answered on 9/1/2017 by InyoPools Product Specialist Lennox H.

Hi, Kent. This B2984T motor can be used to replace the SP3220Z2ME motor. The part number for the OEM replacement is SPX3220Z2MER

?     Asked on 7/4/2017by Bob

What is the temperature range of this motor? I live in Las Vegas where the temperature routinely exceeds the 40 degree C rating on many pumps, and often even exceeds 48. If this pump is not rated at 50 C, which of your similar pumps are? (2 HP, dual speed, 56Y square flange) Thanks.

A  Answered on 7/22/2017 by InyoPools Product Specialist Alex V.

Bob, The motor has a temperature rating of 50°C.

I have a Century Centurion pool and spa duty motor, which is not working. Frame is Y56Y, HP 2.0, SF 1.10, RPM 3450, volts 230. Is this motor comparable with this energy efficient motor. AND are they difficult to install yourself. THANK YOU!!!!!!!

A  Answered on 7/4/2017 by InyoPools Product Specialist Lennox H.

Hi, Matt. This 2-Green B2984T Motor is compatible with the motor you currently have. It's not too difficult to replace a pool pump motor. You can view our How To Replace the Motor on Your Pool Pump guide to see how it's done. 

?     Asked on 6/26/2017by Bill

Does this motor come with the necessary gaskets and if not, which would I buy and do the gaskets come with instructions? Also, assuming my existing impeller is ok, would it work with this motor?

A  Answered on 6/26/2017 by InyoPools Product Specialist Hector F.

These motors do not come with the seals and gaskets. You can call in with the front pump housing model name or number to try and cross reference those parts but if you do not have that information then you can email images to upload@inyopools.com so we can assist. We do have some how to guides on our site and you should be able to use the same impeller as long as it is compatible with this motor.

I have a Jandy model PHPM2,0 pump. Will this motor work with this model?

A  Answered on 6/24/2017 by InyoPools Product Specialist Lennox H.

Hi, Bill. Yes, the Century 2-Green B2984T Motor will fit the PHPM Pump.

I have an old pump motor that needs to be replaced. It is a C48M2PA100, square flange, 2 hp motor with a Max e Pro pump. Can this two speed motor be used? What additional parts will I need.

A  Answered on 3/21/2017 by InyoPools Product Specialist Lennox H.

Hi, Guy. Based on the model number provided you will need the B2983T motor along with the Sta-Rite Max-E-Pro Tune Up Kit - GOKIT79.

A  Answered on 3/20/2017 by InyoPools Product Specialist Lennox H.

Hi, Yes, the B2984T motor can be used with the Max-E-Pro - P6E6G-208L pump. I would also recommend getting the Max-E-Pro Tune Up Kit - GOKIT79.

?     Asked on 3/3/2017by Charles Wendt

Purchased a B2984T on 5/24/14. Installed and ran for ~1.5 years when the LCD display began failing, and in 1/17, was effectively totally shot. Only way to control was with CB. There are NO REPLACEMENT parts for the LCD, so now I have a 2+ year old 2-speed motor that is worthless. If you can now sell me a 'controller' kit and/or parts, I would be ecstatic. If not, answer me, why should I buy this product?

A  Answered on 3/6/2017 by InyoPools Product Specialist Lennox H.

Hi, Charles. Unfortunately, the controller is not repairable. This motor simplifies the use of having an external controller like the T106R Timer in most cases. If you still would like the benefits of a dual speed pump you can use the B984 motor along with the T106R Timer or Toggle Switch and Canopy Kit - 2512558-001

?     Asked on 2/19/2017by BD

My current pump has the same info as this pump (mine says 2 HP, 56Y frame, 3450 RMP, 208-230V) but SF AMP on my pump label is 10.6-10.0 and it says "Class B" for the INS. Can this pump replace my pump?

A  Answered on 2/20/2017 by InyoPools Product Specialist Hector F.

There really isn't quite enough information that you have here to confirm but if you plug in your motor model number, part number or catalog number into our search for an item bar then your specific replacement would come up giving you further specifications of your motor. You can also send in an image through our support request page so we can assist in locating that motor.

?     Asked on 2/10/2017by Jeffrey Sandler

I have a Sta-Rite 2HP P6RA6G-207L motor (bearing is shot). I want to replace it with a dual speed motor. I was told I should buy the B2983T motor. It is rated 1.5/.19 HP. Do I buy this or the B2984T rated at 2.0/2.5 HP. I have a 20,000 gallon pool. Also my pump is four years old, should I upgrade that at the same time?

A  Answered on 2/10/2017 by InyoPools Product Specialist Lennox H.

Hi, Jeffery. The B2983T dual speed motor is the correct motor you will need to operate your pump. If you replace it with the B2984T motor which has a higher total HP than your pump is equipped to handle you will need to replace the impeller also. I would also recommend that you get the Sta-Rite Max-E-Pro Tune Up Kit - GOKIT79.

?     Asked on 1/29/2017by luis a madrid

I have in my pool Sta Rite Max E pro square flanges single Speed, Pump i like is 2Hp full rate Dual Speed W/Digital controller Pump B2984T. I like to know this is the right motor I choose? thankyou for you help.

A  Answered on 1/30/2017 by InyoPools Product Specialist Scott W.

Yes, that motor will fit on your Max-E-Pro. What is the horsepower of your current motor? This is important for me to know so that you are getting the same horsepower, otherwise you will have to get a new impeller as well.

I have a zodiac FHPM 2.0-2 2 speed pump. Would this be a correct replacement?

A  Answered on 1/26/2017 by InyoPools Product Specialist Adam Y.

Yes, This motor will work as a replacement. It has a controller with a timer. If you do not need that then you can get just a dual speed motor. Which would be 2 HP Dual Spd. Motor - Full Rate (B984, B2984) you will also need to replace the shaft seal and the o-rings and you can find those here Jandy Flo Pro Pump FHPM Parts

I need a new motor for a Jandy SHPM 2.0-2. The motor is a Century 2HP 2 speed. The part number is 7-193990-07. Frame Y56Y, Type is CXPM SF 1.10. I am not sure what the part number is I should order. Is the B2984T appropriate? What is the Box on the top and do I need that? Thanks

A  Answered on 8/19/2016 by InyoPools Product Specialist Lennox H.

Hi, The B2983T is the correct motor with controller for the Jandy SHPM20-2 pump and will take the place of p/n 7-193990-07.

will this fit on my EcoStar model # sp3400vsp pump. It is a variable speed now but I would like to install a 2 speed on it

A  Answered on 6/4/2016 by InyoPools Product Specialist Lennox H.

Hi Carl, This B298T Motor can replace the existing motor on the Hayward EcoStar pump. I would also recommend replacing the Shaft Seal - SPX3200SA, Diffuser - SPX4000Z1 and the Housing O-ring - SPX3200T.

?     Asked on 10/28/2015by Steve

Is there such a thing as a two speed motor with just a simple high / low manual switch as opposed to these programmable things with LCD screens?

A  Answered on 10/30/2015 by InyoPools Product Specialist Lennox H.

Hi Steve, The A.O. Smith 2 HP Dual Spd. Full Rate Motor (B2984) would be the motor without the controller and you can use the A.O. Smith 56Y FR Toggle Switch and Canopy (2512558-001) to manually control the speeds.

I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

Why should I purchase a Tune Up Kit?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.

?     Asked on 1/12/2012by Guest

Why do I need to purchase a new shaft seal?

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.

?     Asked on 1/11/2012by Guest

What is Service Factor?

A  Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.
