What is Service Factor?
Reply
Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

What impeller size (3/4hp or 1hp) goes with B638 3/4 hp motor? Thanks,
Reply
The impeller part number will depend on the model of the front pump housing that the motor bolts to. You can call and provide that or if you are not sure than you can send us an image or two of the housing to upload@inyopools.com.
