A built-in mechanical bypass function lets the pump operate smoothly at lower flow conditions with minimal cycling, so it runs quietly and does not short-cycle when a single fixture is opened. The pump uses a co-molded, single-piece diaphragm across 4 chambers, paired with a heavy-duty, seamless shell and an electro-coated motor designed to resist corrosion in the marine environment. O-ring sealed end bells and fully sealed wire entries keep water out of the electrical components for a long service life. This pump is self-priming up to 6 feet and can run dry without damage, making it forgiving during tank changeovers or line work. It is thermally protected and ignition protected, with a sealed pressure switch that is also adjustable to fine-tune the shut-off point. Installation is straightforward: the pump ships with an inlet strainer and two 1\/2 inch hose barb fittings, and it is CE and IMCI Certified (8846) with a 3 year manufacturer's warranty. It is designed for 12V DC marine and RV freshwater plumbing systems and is a direct replacement for pump p\/n 4901.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
