These motors are direct replacements of the "original" motors that came with many pump brands. No pump manufacturer produces their own motors. When the motor is removed or replaced, always replace the mechanical shaft seal. If you do not change the shaft seal, you are risking water damage to the new motor and voiding the warranty. Threaded shaft 56 frame (A.K.A. C-Face or round flange) motors fit most of the popular models of pumps on the market, including Hayward Super Pumps, Super 2, Jacuzzi Magnum, Hayward Max-Flo and many more.
