- [ 4 YEAR WARRANTY ]: Backed by SEAFLO’s industry-leading 4-Year Limited Warranty, this compact diaphragm pump is built for long-term reliability in RV, marine, and off-grid freshwater systems. Designed for continuous real-world use, it provides dependable operation and peace of mind wherever consistent water delivery is essential for comfort and functionality.
- [BUILT TO NSF UL Standards FOR RV POTABLE WATER ]: Built to NSF/ANSI/CAN 61 & 372 (Potable Water Safety), NSF 24 (RV Plumbing), and UL 778 (Motor-Operated Water Pumps) Safe for drinking water and compliant with RV and marine plumbing standards across North America
- [ ULTRA LOW AMP DRAW EFFICIENCY ]: Consuming only 4.0 amps, this pump is ideal for battery-powered systems, solar installations, vans, and small boats where power conservation is critical. It delivers dependable water flow for a single sink or fixture without draining your battery bank, making it a superior choice for energy-conscious off-grid users.
- [ SUPER QUIET OPERATION ]: Engineered for minimal noise, the pump runs no louder than a typical room fan. Rubber isolation feet reduce vibration transfer to surrounding surfaces, creating a comfortable environment in sleeping areas, cabins, and enclosed RV spaces where loud pumps can be disruptive.
- [ COMPACT SINGLE FIXTURE DESIGN ]: Optimized for one sink or light-duty use, this small footprint pump fits tight installations where larger pumps cannot. Perfect for van conversions, small campers, boats, kiosks, or auxiliary water systems, it provides reliable performance without unnecessary size or weight.
- [ ON DEMAND PRESSURE SWITCH ]: The built-in automatic pressure switch starts the pump when a faucet opens and stops it when closed, eliminating the need for an accumulator tank. This ensures convenient operation, reduced water waste, and consistent pressure for everyday use.
- [ ADJUSTABLE PRESSURE SETTING ]: Fine-tune the pump’s shut-off pressure to match your plumbing system requirements. This flexibility helps protect delicate fixtures, reduce cycling, and optimize performance across a wide range of applications from marine galleys to portable water systems.
- [ SELF PRIMING DRY RUN SAFE ]: Self-primes up to 4 feet for flexible installation above or below the water tank. The pump can run dry without damage during intermittent use, while built-in thermal protection prevents overheating, extending service life in demanding conditions.
- [ DURABLE IGNITION PROTECTED BUILD ]: Constructed with a Santoprene diaphragm, corrosion-resistant materials, and ignition protection for marine environments, this pump meets or exceeds RoHS, SGS, and ISO standards. The industry-standard mounting pattern allows easy replacement of similar small pumps.
