[4-YEAR WARRANTY]: Backed by SEAFLO’s 4-Year Limited Warranty, this pump is engineered for rugged marine, RV, and off-grid use. Designed to withstand long hours of operation and variable duty cycles without failure.
[ 5-CHAMBER DIAPHRAGM FOR HIGH FLOW & LOW CYCLING ]: Heavy-duty diaphragm design delivers consistent flow up to 5.5 GPM while minimizing cycling. Runs up to 5 fixtures with no accumulator tank needed.
[ SELF-PRIMING & RUNS DRY WITHOUT DAMAGE ]: Designed to self-prime up to 6 ft (1.8 m), this pump won’t fail or overheat when run dry—ideal for variable or intermittent use in off-grid or mobile systems.
[ BUILT-IN 60 PSI PRESSURE SWITCH ]: Automatically starts and stops when a faucet or nozzle is opened or closed. Provides steady pressure output and improved water control for a home-like experience.
[ QUIET, THERMALLY PROTECTED MOTOR ]: Engineered for silent performance, the sealed motor includes built-in thermal overload protection, extending pump life and preventing burnout under load.
[ EASY INSTALLATION WITH UNIVERSAL PORTS ]: 1/2"-14 MNPT threaded ports fit standard fittings. Compact footprint and standard 2-1/4" × 3-3/16" mount pattern make replacement and upgrades simple.
