SHURflo Aqua King II Fresh Water Pump | Junior, Standard, Premium | 4 Opts

Built for the marine environment and just as happy in an RV. Every Aqua King II has a sealed pressure switch, ignition protection and thermal protection, and runs dry without harm. The Junior and Standard use SHURflo's over-molded one-piece diaphragm (Standard adds the internal bypass); the Premium pumps add a mechanical bypass for low-flow operation with minimal cycling and a seamless-shell electro-coated motor with O-ring-sealed end bells for salt air.
