A.O. Smith M4094 Two Speed, Square Flange 48Y Frame Motor Description

These quality A.O. Smith Square Flange Motors are found on many brands of pool pump. Some of these pool pump brands are Sta-Rite, American Products, Pentair, Waterco, Premier Springwater, Waterway, Jandy, Flotec, Red Jacket, Sears Jet, and others.

These motors directly replace the "original" motor that came with your pool pump. No pump manufacturer manufactures their own motors. We sell A.O. Smith motors because we have found them to be long lasting and reliable. A.O. Smith manufactured motors are the only brand of replacement motor we use in our local repair work.

In our chart below, we match "uprated" motors to their "full rated" equivalents. An uprated motor and a full rated motor are often the same motor with two different labels. We have attempted to simplify this with the chart below.
