The horsepower should be listed on the nameplate (left) of the pump motor (in very tiny letters - hp). If the motor nameplate is burnt or worn off, sometimes a part number of the impeller (right) can tell us which hp your pump motor is.

How do I tell what horsepower wet end pump do I need on my eon spa


Use the information on the motors label.
many times the horsepower and the service factor are not visible because it is intentionally left off. Use the code number or the model number to identify the horsepower with the manufacturer.

How much kw an electric motor 3/4 horsepower use per hour


746w = 1 HP so ~560W or 0.56kW

That's the simple answer...the 'real' answer involves motor efficiency / power factor and what load your pump actually presents to the motor. In the end, it will be somewhere around $0.1 an hour or ~$2.40 if ran all day.

How much horsepower does my intex Crystal Clear Model 635T filter pump have? I'm looking at a hth vacuum that requires at least 1/2 horse power. thanks


If the unit does not have the horsepower rating, but has the AMP rating, try this formula found in Answers.com

"Amps are a factor in calculating power, and so can be used to determine horsepower, but only when other factors are present.
Given other factors, you can find the horsepower. The easiest way is to determine watts by multiplying amps X volts. Next multiply watts by .00134 and you have horsepower.
If: amps (A)= 20 and volts (V)=120 then
A X V =2400 watts (W)
2400 watts X .00134 = 3.216 horsepower"

Hope this helps you???

I have an 11 year old Jacuzzi Magnum Force 1227 pool pump model 15UMFS. I want to replace it, but don't know how many horsepower it is. Can you tell me?


Probably 1.5 HP but if you can read any of the nameplate data on the motor it would be helpful to confirm. A better approach might be to size the new pump to the volume of water in the pool.

If all you are going to replace is the pumps motor then can you provide at least the amp ratings off the motor? Those should help verify what your old unit's horsepower really is.

I have a older spa with a Sta Rite pump motor. Without removing the damaged pump I was able to see the model number of the pump through a mirror. I beleive it reads K48M5A3, is there any way that you can...


That would definitely be the model number. The K indicates Capacitor start and run, the 48 indicates the frame size, and the "M" indicates horsepower (1.5 hp, in your case). If your replacing the motor, make sure you get the same Horsepower and Service Factor ratings. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!

Spa tub motor need replacing


I havent seen to many motors this old, but today all you really need to know is the horsepower and the frame (either round or square). Pull the old one off and take it to a pool store, and they can probably get it for you.

Also..im not sure but i think A.O. Smith bought out magnetek some years back....
