NOTE:
Check pump and motor nameplates before ordering impellers. Select proper part by determining pump
size, material, motor type and HP. Pump size 11⁄2 x 2– 8 after October 1987 will have nameplate index – 1
(19; 5BF11135-1, with 63⁄4" impeller) indicating new impeller sizes, consult curves with price sheets. Prior
to October 1987, order old style impeller from list on back. Consult factory when ordering repair parts for
pumps having a factory order number as the index number.

▼ All bronze models produced after December, 1987 have cast iron motor adapters and bronze seal
housings. When ordering motor adapters for repairs, order “K” number listed by pump size, construction
and motor frame size. These motor adapter assemblies are interchangeable with old style one piece adapter.
