Self-Priming Design
Once pump is primed, filled with water, it never needs priming again even if water level drops below the end of the suction pipe. Pumping resumes once the water level rises above the end of the suction pipe.

Back pullout design allows disassembly of pump for service without disturbing piping.Two compartment motor for easy access to motor wiring and replaceable components.

Diffuser (Guidevane)
Bolt down diffuser provides positive alignment with impeller. Diffuser has stainless wear ring for extended performance in abrasive conditions. F.D.A. compliant, injection molded, food grade, glass filled Lexan® for durability and abrasion resistance.
