Motor Replacement

newport2001January 23, 2011

We had a sta-rite motor that was replaced with a century centurion. Is the century any good? We have a home warranty on the home so their pool contractor for the area came out and replaced it. Unfortunately I wasn't home at the time and they have the old pump so I don't know which sta-rite model it was.

The only thing I do know is that our sta-rite was a 2.5hp and now we have a 2hp. I definitely will be saying something about that. We have a 31k gallon pool.

Any input would be greatly appreciated. Thanks.

If your plumbing is 2" or smaller, don't complain. The 2 HP will eat less power and push about the same amount of water. Bigger is not usually better.

A 2.5 HP motor with the proper sized impeller needs bigger plumbing than most older pools have. I take it you are not in California or Title 20 rules would have required a 2 speed or variable speed pump.

Did you mean to say that they replaced the entire pump or just the motor on the existing pump?

With just a motor replacement, the new motor service factor HP should have been at least as big as the old motor.

Sorry, yes they just replaced the motor. How does the Century compare with the Sta-Rite that I had. Thanks.

The motor on the Sta-Rite is not made by them. I prefer A.O. Smith but Century is ok too.

A 2.5HP 1.1 SF , and 2hp 1.25+ SF motor are the exact same motor.

Check the SF on the new motor if it's above 1.25 you are good.

There is a term call "up-rate" which means a sales schmuck can sell a bigger pump, and have a more impressive number on his bid sheet.

I hope with stuff like title 20 forcing service techs, and salesmen to put more thought into energy efficiency this whole BS practice Uprating pumps dies.
