Pump Motor Replacement Options (Other than Century)

Aug 4, 2008

I just replaced the motor, impeller and diffuser on a Sta-Rite Max E Pro 2HP pump (PE6EG-208L). The original pump/motor was very quiet for 9 years (until it started to fail).

The motor I ordered was a USQ1202 made by Century (formerly AO Smith). The original Motor has A.O. Smith written on it but there's no model number. The Sta-Rite Part number is AE100GHL.

Everything fit fine and it all works, but it's much more noisy than before.

My questions are:
1) Does Pentair/Sta-Rite specify better (more quiet) bearings for their version of the AO Smith Motor?
2) Rather than ordering the Pentair/Sta-Rite version (AE100GHL), can we order a version of the USQ1202 motor with improved bearings?
3) Is there another company that makes a replacement motor that's better than Century?

Edit: I just noticed that that SQ1202 is considered the exact replacement by Century. It has a higher service factor than the USQ1202 making it more efficient but I'm not sure that it means the bearings are better or more quiet.
 
Century bearing are just as quite as any other brand. I would inspect all the parts again to make sure you assembled the pump correctly.

Can you post a video with sound?
