Shurflo by Pentair Self-Priming Dual Blade Macerator Pump - 24VDC, 13GPM

The Shurflo by Pentair Self-Priming Dual Blade Macerator Pump – 24VDC, 13GPM is engineered for marine and RV sanitation systems where reliable waste water handling is essential. This pump is purpose-built for galley and head applications, converting solid waste into a pumpable slurry that can be discharged through small-diameter hoses to holding tanks or overboard systems. Marine operators and RV owners depend on macerator pumps like this model to eliminate the need for large, rigid waste pipes, simplifying plumbing layouts in confined spaces and improving system flexibility.

Built by Pentair—a trusted name in marine fluid handling—this pump features dual cutting blades that macerate waste effectively while the self-priming design eliminates the need for manual priming before operation. The 24-volt DC electrical specification makes it ideal for standard marine 24V battery systems, delivering 13 gallons per minute (GPM) of consistent flow under normal operating conditions. The compact 6 × 5 × 11-inch footprint and lightweight 5.2-pound construction allow for easy installation in tight engine compartments or under-galley locations. Its durable construction handles the corrosive marine environment, ensuring longevity in saltwater and freshwater applications alike.

This pump is compatible with standard marine sanitation systems found in cruising sailboats, trawlers, cabin cruisers, and Class B motorhomes where integrated waste handling is required. Installation typically involves connecting inlet lines from the galley and head areas to the pump intake, with discharge routed to the holding tank or through a Y-valve to the overboard through-hull fitting. Operators should verify 24VDC system compatibility and ensure proper circuit protection with an appropriate marine-grade breaker before commissioning. Regular maintenance of intake strainers will maximize pump life and performance in your marine plumbing system.
