Model: 317301200
Power: 12V DC
Series: SeaLand T Series
Pump Type: Waste Discharge / Macerator Pump
Application: Marine Sanitation Systems
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).
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.
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.
Engineered with corrosion-resistant components and sealed construction, the SeaLand T Series pump is built to withstand saltwater exposure, vibration, and continuous marine use.
Bellows Technology: The unique reciprocating bellows design allows the pump to handle solids and air pockets without losing prime or sustaining damage.
Run-Dry Capability: Unlike centrifugal pumps, the T-Series can run dry indefinitely without damaging the motor or the pumping mechanism.
Self-Priming: Capable of priming up to 10 vertical feet (3 meters), providing flexibility in installation locations.
Low Power Consumption: Efficient 12V motor draws only 6 Amps, making it easy on your battery banks
Odor-Safe Performance: Designed to work with 1.5-inch sanitation hoses, ensuring a secure, leak-proof, and odor-free system.
