Description These self-priming (to 6 ft. lift) centrifugal pumps are designed for continuous duty, general purpose liquid transfer. Applications include livewell recirculation, marine air conditioning, and salt water aquaculture. Pumps feature bronze construction, Buna N seals, and a semi-open clog resistant impeller capable of handling solids to 1/8" diameter. Handle liquids from 40. F to 180. F (4. C to 82. C). Maximum working pressure 75 psi (517 kPa). Single phase motors have automatic reset thermal protection. All models are manual mode and require field wiring, no controls are supplied (see motor nameplate for specific wiring diagram). For use with nonflammable, non-abrasive liquids compatible with pump component materials.
