SEAFLO 56 Series Portable Washdown Pump Kit, 12V DC, 5.0 GPM, 70 PSI

The SEAFLO 56 Series Portable Washdown Pump Kit (Model SFWP1-050-070-56P) is a 12V DC, self-priming washdown system engineered for marine, RV, outdoor, or off-grid cleaning tasks, delivering up to 5.0 GPM (18.9 L/min) and cutting off at 70 PSI (4.8 bar) for powerful spray performance. The kit is built around a five-chamber diaphragm pump with EPDM valves and a Santoprene diaphragm, encased in a waterproof (IPX6) housing, and comes complete with a UV-protected 16.4 ft (≈5 m) coiled hose, adjustable spray nozzle, inline strainer, quick-connect fittings, and a vibration-dampened base for quiet, stable operation. It is self-priming (suction lift up to 6 ft / 1.8 m), run-dry safe, and designed for portable, ready-to-use washdown — ideal for small boats, dinghies, RV exteriors, decks, anchor wells, or garden/outdoor cleaning.
