These quality Magnetek Century Threaded Shaft Motors are found on many brands of pool pump. Some of these pool pump brands are Jacuzzi, Hayward, 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.
