FloJet RV Macerator Pump – Model 18550000A

The FloJet RV Macerator Pump (18550000A) is a high-performance 12V or 24V (depending on configuration) pump designed to provide efficient, reliable waste disposal for RV and marine systems. This macerator pump grinds and pumps waste, allowing for quick and clean emptying of black and gray water tanks directly into approved sewer outlets or dump stations.

Equipped with a powerful macerator blade assembly, the FloJet 18550000A reduces solids into small particles, minimizing the risk of clogs and improving overall flow. Its compact, lightweight design makes installation easy in tight spaces, while durable, corrosion-resistant materials ensure long-lasting performance in harsh RV and marine environments.

The pump features automatic or manual operation options, offering convenient, hands-free functionality while providing consistent performance with minimal maintenance. Ideal for both residential-style RV waste management and off-grid marine systems, this macerator pump ensures hygienic, efficient waste disposal for travelers and boaters.

Key Features

• Macerating Power: Features a heavy-duty stainless steel cutter that reduces waste and toilet tissue to a fine slurry for easy discharge.

• Run-Dry Protection: Includes an exclusive protection device that automatically shuts the pump off after 20 seconds of dry running to prevent motor and impeller damage.

• Fast Evacuation: With a flow rate of up to 13 GPM (49 LPM), it can empty a typical 30-gallon holding tank in less than three minutes.

• Manual Turn Key: Features a rear motor shaft slot that allows you to manually break loose a stuck impeller (common after long periods of storage) using a simple screwdriver.

• Self-Priming: The flexible impeller design allows the pump to prime itself up to 4 vertical feet, providing flexibility in mounting locations.
