It delivers a maximum flow rate of 5 gallons per minute and shuts off at 55 PSI, giving multi-fixture systems steady, home-like shower and faucet pressure instead of the pulsing flow common with lower-capacity pumps. A built-in mechanical bypass function lets the pump operate smoothly at lower flow conditions with minimal cycling, which reduces wear during light-demand draws like a single open faucet.\u003c\/p\u003e\u003cp\u003eThe pump is self-priming to 6 feet, so it can draw water up from a tank below the pump without manual priming. Its housing uses a heavy-duty, seamless shell with an electro-coated motor designed to withstand the marine environment, along with o-ring sealed end bells and fully sealed wire entries to keep moisture out of the electrical connections. Wetted components are built from EPDM, polypropylene (PP), Santoprene, and stainless steel for corrosion resistance and long service life in freshwater transfer applications. The pump measures 12 inches long by 6 inches wide by 6 inches high and is intended for above-ground, general freshwater transfer and marine freshwater pump use.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
