I don't believe that AO Smith makes the pump - just the motor. I have a Purex Triton Maxim Pump connected to an AO Smith BN35 motor - 1.5 HP, 2.0 SPL. I've had it for 5 seasons, running it approximately 8 to 12 hours a day, sometimes 24 hours for several days to clear out algae problems, and shutting it down from October to April.

It is still working. However, I am going to replace it for this season. Based on the advice by many on this forum, it appears to be oversized by the dealer, and I want to go to a 1/2 or 3/4 HP pump/motor for my 14,000 gallon pool to save on energy costs.
