Ive searched the internet and even called pentair, but im getting conflicting info.

I have a 2hp pentair superflo pump  The motor is going out on it and I need a new one.  I want to downsize to 1.5hp due to only having a 10,000 gallon pool.  I have been told by leslies techs and I saw a post here that says you can use the same diffuser and impeller for both.  But Pentair says no.

Does anyone have a definiate (i did it and it works) answer? 

 

Thanks

If you downsize the motor, you'll need to downsize the impeller as well. What is the catalog or part number on your motor label? We can recommend the correct impeller and motor based on that information.

This is the third time in 26 years I have had to replace a burned out pool pump motor. After the first motor burned out, I upgraded my 1.5 HP Pac Fab Challenger motor with a 2 HP high performance Whisper Flo Pentair motor. This time I found that my impeller 35-5086 was damaged, It worked fine with the last 2 pumps I installed. Is this same impeller P?N 35-5086 compatible with both the 1.5 HP & 2 HP motors .

Hi, Robert. Yes, this Impeller - 355086 can be used with a 1.5 HP Full Rated or 2.0 HP Up Rated motor.

The 340040 Superflo is an uprated 2HP pump. The total HP rating is 2.2 (SF x HP). The next step down would be a 1.5HP uprated motor. The motor number will be B2854 (total HP 1.65). The impeller that matches the motor will be part number 35-5074.

The total HP rating of the impeller should be equal to or less than the total HP of the motor. If the impeller rating is higher, it will cause the motor to fail.

So both of those items will fit the original pump body and work the the origianal diffuser?  will I need new ceramic seals?

InyoRob posted this 06 December 2021

Both parts will work with the original body and the diffuser will remain the same. The seal kit is part number GOKIT78.
