Designed to deliver smooth, consistent flow of 2.0 GPM without rapid cycling, it is well suited to boats with a single fixture or light multi-fixture demand such as a galley faucet, head, or shower. The pump uses a unique over-molded, single-piece 4 chamber diaphragm along with a corrosion-resistant motor and an adjustable pressure switch, allowing it to hold steady pressure as demand changes.\u003c\/p\u003e\u003cp\u003eBuilt for reliability aboard a boat, the Aqua King II Junior is thermally protected, ignition protected, and rated to run dry without damage, so an empty tank or temporary loss of water supply will not harm the motor. It is intended for intermittent duty rather than continuous running. The pump ships with two 1\/2 inch hose barb fittings for straightforward plumbing hookup and is backed by a three year manufacturer's warranty.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
