Replacing Motor

[JDunks]

I hoping someone can help. My pool motor starting making weird noises after the water got low and it started pulling air.
Fast forward to 3 weeks later and now it has stopped working completely. It hums for 2 seconds then cuts out. I took tried to stick a screwdriver in the hole on the filter side to spin the impeller but count locate it. I will get the pump rebuilt but i was also considering buying a new one. I have attached the original pumps specs along with the one Id like to purchase. Could someone tell me if I have the right one? Thanks Century Centurion E-Plus 1081 Series 2 HP, 56J Frame Motor B809 - C-Face

If the budget permits, a variable speed pump is a good idea. Lots more flexibility in how you run your pool. Quieter. And at least a good part of the higher cost comes back in lower power costs.

Total horsepower of your existing motor - 2.5. Total horsepower of the motor you reference - 1.95. You can't use it with your existing impeller or it will burn out quickly.

The motor on your pump was made by Century specifically for that pump application. You can find it here:

1poolman1 Thanks for the reply. I have a spa and Jandy Aqualinks. So how do I make sure the spa still runs correctly, and also maintain control over the new motor? Thanks for the help.

If you use the 2-speed motor there are no changes. Just replace wire-for-wire in the new motor.

If I wanted to put in the VS motor what would I need to do in order to have it work with the Auqalink?

Does your Jandy support a VSP? That's the first question to be answered.

Probably not as its 20 years old and hasn't been updated. I ended up getting a new 2 speed pump. Now I'm trying to figure out how to make it run in low speed by default. created another thread about that.
