Built with a Honeywell micro switch, Viton valves, and a Santoprene diaphragm inside a fiberglass-reinforced polypropylene manifold, it combines corrosion resistance with long-life components. Standard 3\/8\" hose barb ports and the included worm-gear clamps make installation fast, and a CE-approved mounting pattern helps retrofit it into existing systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will this pump move liquid and what pressure can it maintain?\u003c\/h3\u003e\n\u003cp\u003eThe Everflo 12V pump delivers up to 1.0 gallons per minute and a maximum pressure of 40 PSI, suitable for many agricultural spraying and transfer tasks.
