Magnetek/Century M4098 One Speed, Square Flange 56 Frame Motor Description

These quality Magnetek Century 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 Century Electric motors because we have found them to be long lasting and reliable. Century Electric Motor is now part of A.O. Smith.

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.
