Reliable Waste Discharge for Marine Holding Tanks
The Dometic SeaLand T Series Waste Discharge Pump (12V) is a dependable solution for evacuating marine holding tanks quickly and cleanly. Designed for SeaLand sanitation systems, this pump delivers strong, consistent flow to move waste to dockside pump-out stations or overboard discharge systems (where legal).
Powerful Macerator Performance
Built to handle marine waste efficiently, this pump macerates and transfers waste smoothly through discharge lines—helping reduce clogs and keeping your sanitation system running reliably.
12V DC Marine-Grade Power
Runs on standard 12V DC power for easy integration into most boat electrical systems. Ideal for replacements or upgrades on boats equipped with Dometic SeaLand systems.
Built for Harsh Marine Environments
Engineered with corrosion-resistant components and sealed construction, the SeaLand T Series pump is built to withstand saltwater exposure, vibration, and continuous marine use.
