[ 4 YEAR WARRANTY ]: Backed by SEAFLO’s industry-leading 4-Year Limited Warranty, this system delivers long-term reliability and peace of mind for marine, RV, and off-grid users who demand dependable water pressure performance in critical applications

[ SELF-PRIMING AND RUN-DRY CAPABLE ]: Capable of self-priming up to 6 feet (1.8 m), this pump is designed to run dry without damage, ensuring reliable performance in any installation.

[ ACCUMULATOR ASSISTED SMOOTH FLOW ]: The integrated 2 gallon pre-pressurized tank works with the five-chamber diaphragm pump to reduce cycling, eliminate pulsation, and provide consistent, quiet water flow across multiple fixtures and outlets

[ SAFE FOR POTABLE WATER APPLICATIONS ]: Built with maintenance-free, potable water quality materials, this system is ideal for drinking water systems in boats, RVs, and off-grid setups.

[ EXTENDED PUMP LIFE AND EFFICIENCY ]: The accumulator reduces on off cycling, lowers overall amp draw, minimizes heat buildup, and significantly extends pump lifespan, making it ideal for battery-powered RV and off-grid water systems

[ IGNITION PROTECTED FOR MARINE USE ]: Compliant with USCG 183.410 and ISO 8846 MARINE standards, the pump ensures safe operation in marine environments.

[ NSF UL CSA CERTIFIED SYSTEM ]: Tested to NSF potable water standards and UL CSA safety certifications, this system is approved for drinking water applications and meets strict marine and RV compliance requirements

[ DURABLE SANTOPRENE EPDM CONSTRUCTION ]: High-quality diaphragm and valve materials resist chemicals, scaling, and wear, ensuring long-lasting performance in both freshwater and saltwater environments

The SEAFLO Marine Water Pump and 2 Gallon Accumulator Tank System delivers smooth, quiet, constant water pressure for boats, RVs, motorhomes, and off-grid cabins. The integrated 5.5 GPM, 60 PSI diaphragm pump and pre-pressurized accumulator tank are factory-mounted on a single board for fast install and professional performance. A five-chamber diaphragm head paired with the 2 gallon accumulator dramatically reduces pump cycling and pressure spikes, giving you steady flow at the tap and far quieter operation than pump-only systems. Built with Santoprene / EPDM internals, this system is tough enough for freshwater or saltwater use in demanding marine and RV environments. Certified for potable water and compliant with NSF/ANSI/CAN 61 & 372, NSF 24, UL 778, and CSA C22.2 No.108, this system is safe for drinking water plumbing and ignition protected for use on board. With self-priming up to 6 ft, run-dry capability, and SEAFLO’s 4-Year Limited Warranty, it’s a long-term upgrade to any pressure water system.
