Note:
XX - Impeller Code - First X equals diameter of impeller in inches minus 4. Therefore 10" = 6, 9"= 5,8"=4, etc… 14" use letter A.
Second X equals fractional data in 1/8's. Therefore 1/8" = 1, 1/4" = 2, 1/2" = 4, etc…Thus a 10.5" impeller is coded as 64, a 12" impeller is coded as 80, a 13.25" impeller is coded as 92 etc.
