AO Smith Centurion 1081 Square Flange Up-Rated Motor 2 HP - B855

The B855 Replacement Square Flange 2 HP Pool Pump Motor is a very reliable motor. This replacement pump motor is manufactured by Century Electric, formerly AO Smith, and comes complete with the manufacturer one year warranty.


AO Smith motors are the same motors used by the major pool manufacturers (Hayward, Zodiac/Jandy, and Pentair/Sta-Rite) making them the true OEM (original equipment manufacturer) replacement pool pump part. If you look on your current motor label, you will more than likely see the pump manufacturer name, and then “Made by AO Smith” smaller towards the bottom.


The B855 motor is a replacement motor for many different pump brands.  **We still recommend confirming the motor replacement if your existing motor doesn’t show the B855 model number on the label. You can send a picture of your label to us using our motor replacement form for assistance, found here.

A.O. Smith was recently acquired by Century Electric Motors.You can expect the same great quality motors from Century Electric. Motors are now labeled as Century Electric formerly A.O. Smith.
