I currently have this motor (well, its equivalent - Mod# 193987) installed on my pump, but it died. This is my second dead motor in 6 years. Our original one was a variable speed and I'm thinking it might make more sense to go back to that kind, but I'm not sure what the variable speed equivalent is for this. Can you suggest something?

Hi: can you let me know any less expensive replacements for the B2859 motor? I live in Fl. Also, any reasonably priced pumps that would fit this motor? My PHPM2.0 pump needs replacement too. Thanks

Unfortunately, we do not have any other cheaper single speed motors for a replacement and I would consider the Pentair Superflo series pump for another complete pump option that can use that motor.

You can use either a dual speed motor part number B983 which can use a toggle switch which is listed in the product details or you can use a dual speed timer for it being part number T106R. Lastly, you can also use a variable speed motor part number ECM27SQU which will not any toggle switch or secondary timer.

Hello: I need to replace my current pump that is a square flange 1.5HP Century C48D43A04. I wanted to try to get an upgraded replacement as I wasn't happy with the performance of my current one that has gone bad in just over 3 years. Would this (A.O. Smith 2 HP, 56Y Frame, Up-Rate Motor 230/115 (B859, B2859) pump be compatible with my current pump? Thanks very much! Rich G.
Reply
Good morning, based on the number provided C48D43A04 the A.O. Smith 2 HP, 56Y Frame, Up-Rate Motor 230/115 (B859, B2859) would be the correct motor. One thing to always keep in mind is changing the shaft seal and or the seal plate of the pump.

I am in California and have a Century Centurion CAT B859 Part 7 -177217 - 25 2 HP. Is there an alternative drop in replacement?
Reply
Peter, If you live in California, you will need to replace your single speed motor with a 2-speed motor in order to be in compliance with your local laws. You can replace your B859 with the B985. Please note that the B985 motor will only operate on 230v. You will either need a 2-speed switch or a 2-speed timer to operate the high and low speed. Also, be sure to change your shaft seal when you replace the motor.

I have a Pentair WhisperFLow pump and need a new 2 HP motor. What is the correct motoor for this pump. B855 or B859.
Reply
Hi, Robert. Between the B855 and B859 motor you can use either, the difference is that the B855 is rated for 230 volts only and the B859 is rated for 115/230 volts. Also, confirm the service factor (SF) of your existing motor, both of these motors have an SF of 1.10. I will also recommend that you get the Whisperflo Tune Up Kit - GOKIT32 or GOKIT32SALT.

I need to replace the motor on my Pentair WF-28, 1.1 SF, 2 HP pump. The almond pump does not seem to have the original motor but a black A.O. Smith motor which might have been replaced by the previous owner. The label from the motor is not available. Which motor should I order? B859/B2859 OR B855/2855? What is the difference between the two. What additional seals/kits will I need? This is the first time I am doing it by myself.
Reply
Hi. I would recommend the B859/B2859 since it's a dual voltage motor if you're not sure of the operating voltage. The B855 motor is rated at 230 volts only and the B859 motor is rated at 115/230 volts. You will also need to get the Whisperflo Tune Up Kit - GOKIT32 or GOKIT32SALT.

Ralph, There are several options for a replacement motor. If you are replacing a 56Y frame motor, this will be an exact replacement. If you are replacing a 48Y frame motor, you would need the USQ1202. Please be sure to replace the shaft seal when you replace the motor.

Do you have the model of your pump, not the motor? If not, if you could attach a picture of the complete pump so I can identify what you have to make things easier finding the motor and seals.

My motor part number is 0-193987-24, just double checking to make sure this is the correct replacement, it will be running A Jandy Pro Series pump model number PHPM2.0. Do i need any other parts to complete my rebuild?
Reply
That is the correct motor replacement and we advise to replace the shaft seal, back plate o-ring and the diffuser/impeller hardware. You may need the old or new style shaft seal. If the serial number on your front pump housing reads with a Pxxxxx or earlier then you would use the old style part number 5020-086. If not then use the new style part number 5020-087.

Why should I purchase a Tune Up Kit?
Reply
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.
Reply
Why do I need to purchase a new shaft seal?
Reply
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.
Reply
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.

Pros: Customer service, shipping time, price and product
Cons: None that I can think of
Best of all is the wonderful customer service help provided by Inyopools. The product was here in the time specified and the price was considerably less than the 5 other companies I checked with first. The product was as specified and ordered and hasn't given me any problems to date. It was installed about a month ago.

We got this to replace an existing motor in our Whisperflo pool pump. The ordering process was easy and we received the motor the next day. Everything went smoothly when replacing the old motor and so far it is working great and makes far less noise than the old one. I also did research on pricing and this was a reasonable price in comparison to other places.

Pros: best prices and fast shipping
Cons: none that I know of
Where to start. I needed a new pool pump motor. Called the 2 local chains and was quoted between 450 and 489 bucks for the motor. Looked up Inyo pool products. Motor including shipping was 280 dollars. That is what I call a savings. This was the brand name motor not some knock off. Motor got here in 3 or 4 days. I expect markup from the locals but 200 bucks is just too much. If I need pool equipment I know where I am going from here on out. Motor arrived in great shape.
