How do I determine Wet End HP when I only have voltage and amp rating?

[Wingryder]

Replacing Wet End  but have not  removed the pump yet.  Would like to have new Wet End ordered and here before draining spa.

I am confused about HP rating  The   motor is two speed  Magnetek  mated to a Waterway,  230 volt  with amp ratings of 8.5 /2.4   I am told this  would need a 1 horse wet end.  Others say a 3hp would work if rated for a 8.5 amp motor.     Which is it??

thanks

8 amp 2 hp, 10 amp 3 hp, 12 amp 4hp

Thanks for the quick response.  I now have 1,2,and 3hp  as answers to my question.  I think you nailed it with 2hp.  I did the calculation with input voltage and amp and it's  2.6 or so horsepower.  Probably isn't super critical..I mainly use the low side of this motor for circulation and heating.  

Thanks CanadianSpaTech

Is the original wet end cracked?

[Wingryder]

No it is working fine but does show some previous  minor  leaking.  I am replacing bearings and thought I would just slip in a new wet end since its pretty old.

One more question.   Would it hurt anything to cut the old bearings off the armature/rotor with a small cut-off wheel.  Provision would have to be done to protect windings of course.  Or just go get a new puller??  (old one got abused)

Do you feel lucky? Roll them dice.

I would use a puller.
