What is Service Factor?
Reply
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.

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?

Is this the correct replacement motor for a 2008 pentair PMP WFDS-6 230v 1 1/2HP, p/n 011522?

Hi David, This B2983 motor is the correct replacement motor for the WFDS-6 pump. I would also recommend that the get the Pentair/Purex Whisperflo Tune Up Kit p/n GOKIT32 or GOKIT32SALT.

How much is actually saved in electrical costs going from a 2-speed to a variable speed. Trying to determine the payback equation.

Hi. They're several calculation tools that you can use depending on the manufacturer. If you would like to just change the motor with the Century V-Green VS Motor, you can use the V-Green Calculator.

Hi, I'm replacing a Pentair WFE-6 /011514, and see you recommend this pump motor as a replacement. I have solar panels on my roof (two story home), will this be enough on low speed to circulate through the panels? Also, all my relays on my controller are used by other options (spa air pump, pool lights, spa lights, etc.) do you have any options for using the low speed in this situation? Thanks.
Reply
Hi, Dan. Operating the pump on low speed will not provide enough water flow to operate the solar. I will need to know the model of your controller to find out your options.

I live in California that now requires a VSP. Other than a seal kit, does the switch to a VSP require additional components?
Reply
Hi, Guest. A VSP requires 230 volt electrical and some requires an external timer. Otherwise, no additional components are required.

I need to buy this replacement motor. changing it for the first time, for Jandy 2 speed stealth pro series stealth pump. The pump has become noisy.
Can you recommend the parts I need to buy along with this motor?. The label is attached. I know that I should buy a new seal. The pump seems to be expensive. Any discounts will be appreciated.
Thanks Ipe
Hi, Ipe. You will also need to replace the Pump Shaft Seal - R0445500 or R0479400, Diffuser O-Ring - R0622000, and Backplate O-Ring - R0446300. Other parts are listed on the Jandy Stealth SHPF & SHPM Series Pump (2008-Current) Parts Diagram page.

can you also confirm the motor is correct replacement B 2983? Any cheaper appropriate and efficient 2 speed motors?
Reply
Ipe, The B2983 motor is the correct replacement. There is not a cheaper option available.
Reply
Would either pump shaft seal mentioned above will work.
Reply
Ipe, No, only one shaft seal will work based on the age of your pump or if the impeller is original.
Reply
Impeller should be original. Pump was installed in 2015. Which one is the right seal then?
Reply
Ipe, The Pump Shaft Seal - R0479400.

Thank you for the recommendations. I bought all the parts.

I got all the parts. The motor seal and washers fit perfect. Confused with wiring because the leads are not marked the same way. I have green blue black and red wires. My system has Hi and Lo toggle switch for 2 speeds. Attaching old motor wired and and new motor empty leads. Could you guide me where black blue and red goes. Thank you
Ipe, The motor will be wired L1 = Red, L2 = Blue, A= Black, Green = Ground Screw.
Reply
Just FYI, the connection you said was wrong, my connection was correct. When I attempted yours, the breaker went off. Luckily didn’t burn the pump. I reversed the connection as showed in the picture. Blue to L1, Red to L2 , black to A and Green to ground. I am attaching a link to my YouTube video which could help similar customers. Thank you for your help. https://youtu.be/EENSQgw5DVE

Hi if i'm trying to switch my single speed Century 1.5 HP Square Flange 56Y to a dual speed motor. is this one correct? also anything else i'd need to change to upgrade?
thanks
Hi, Nom. Yes, this B2983 is the correct dual speed replacement motor.
Reply
i think i also need the high/low switch to convert from single to dual. is there a seal kit for this model? can you link to that please.
Reply
Hi Norman, the toggle switch is part number 2512558-001 which is currently a special order however you can also use Intermatic dual speed timer part number T106R. And in order to locate the seals and gaskets, we will need ti to know the model name or number of the front pump housing wet end that the motor attaches to. Or you can provide an image of that pump housing here as well.

Hello will this work for SPX3215Z2BE
Hi Albert, yes this is the correct replacement motor for your motor model SPX3215Z2BE. When replacing a pool motor we do suggest a Seal Kit. Could you send us a few photos of your pump so we can suggest the proper seal kit? If so then please take a wide shot of the complete pump to include the pipes going in and out of the pump. To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation for your seal kit.

Is the B2983 a suitable replacement for whisperflo wfe 6 1.5 motor?
Yes, the B2983 could be used as a 2-speed motor option for the Whisperflo WFE-6. The motor does not come with a hi/lo switch. If you don't currently have a control system that can switch the speeds, you can order the toggle switch separately. The part number is 2512558-001.

I am looking for the 1.88hp version of this pump motor.
Hi Austin you will require this 1.88 Total HP Dual Speed Motor for the motor included in your photo. You will also need a Hayward Tri-Star Seal Kit when you replace your motor. We put together this Video on How to Replace a Pool Pump Motor which you may find helpful when you tackle this project.

I will be replacing my single speed motor (pic added) with a dual speed. Is this the correct part?
Hi Mike, the Dual Speed Full Rate Motor - B2983 will be a perfect dual-speed replacement for your current motor. Let us know what the model of the pump is that the motor attaches to so we can recommend a new motor shaft seal or tune-up kit for a leak-free installation.

I have a B2983 motor with toggle switch kit that I got from you just two years ago as a California mandatory replacement for my B2842. Servicing the pool this morning I found that the motor will not run but will just "buzz" with the toggle switch in the "High" position. It will run with the toggle switch in the "Low" position but certainly doesn't move enough water to get the job done. There is no water intrusion evident. Can this be fixed without replacing the whole motor?
Thanks, Ed

Hello Edward. A Run Capacitor failure on a dual-speed motor will typically result in the motor running on only 1 speed. Attached please find 2 brief tutorials How to Test a Pool Pump Capacitor and How To Find The Correct Capacitor For Your Pool Pump Motor Please provide Voltage and Microfarad (uF) information from the current capacitor and a replacement recommendation can be made.

Is this replacement I need?
Hello Matt. The Century Motors model B2983 is NOT compatible with the Hayward Super Pump. The Century 1.0 HP Round Flange 56J Dual Speed Full Rate Motor - STS1102RV1 is a compatible replacement for the Century Motors model 7-177653-03. The Tune Up Kit Hayward Super Pump - GOKIT3 contains the seals and gasket necessary to complete the motor change.

A bit confused here- I ordered the Century B2983 1.5hp motor on 6/3/23. I am replacing a Century 9-193990-07. My current pump reads 2.0hp on the cover, but in the chat before I ordered the INYO tech recommended the B2983. Should I have ordered the b2984 (2.0 hp?). The pool runs a hot-tub and a fountain feature as well.
Hello David, yes the model B2983 is a correct singe speed replacement motor for your motor part number 193990. Essentially it is a full rated motor which means that its total HP is different than what is just stated in the HP line on the motor label. We know that understanding the motor manufacturers specs can be confusing so here is our blog that we put together called "How To Understand True Pump Horsepower - Up Rated vs Full Rated" that should clarify.
