Shurflo Aqua King II Standard 12V Fresh Water Pump, 3.0 GPM, Model 4138-111-E65

The Shurflo Aqua King II Standard is a 12 volt DC submersible diaphragm pump built for fresh water plumbing systems on boats and RVs. It delivers a maximum flow rate of 3 gallons per minute and maintains constant water pressure at low flow rates without cycling, shutting off at 30 PSI once system pressure is reached. The pump is self priming and can run dry without damage, making it a reliable choice for onboard water systems where intermittent use and occasional loss of prime are common.

Construction features a single-piece, over-molded diaphragm with an internal by-pass for long life and consistent performance. The housing has an electro-coated seamless shell with O-ring sealed end bells, and all wire entries are fully sealed to keep water out of the electrical connections. The pump is ignition protected and includes a thermal breaker for protection against overheating. It ships with fittings and a twist-on inlet strainer for installation. The unit measures 12 inches in length, 6 inches in width, and 5 inches in height, and is finished in beige plastic.

This pump is designed for marine plumbing systems and RV plumbing systems, supplying fresh water to sinks, showers, and other onboard fixtures.
