SeaLand T Series 12V Discharge Pump - Model 317301200
Emptying a holding tank shouldn't be a gamble every time you flip the switch. The SeaLand T Series Discharge Pump was built around a simple idea: a pump that keeps working even when conditions aren't perfect. Unlike impeller-style macerator pumps that can burn out the moment they run dry, this bellows-style design shrugs off dry running without any damage to the motor, giving boat owners one less thing to worry about during a busy day on the water.
Rated to move 300 gallons per hour while pulling just 6 amps at 12 volts, this pump strikes a practical balance between power and efficiency. It self-primes to a lift of 10 feet, so it can handle tank placements that would leave weaker pumps struggling. For boats already running a Dometic Tank Discharge control system, the T Series pump integrates directly into that setup, allowing fully automated discharge in waters where overboard release is permitted.
As a direct replacement for Dometic part number 9108554778, installation is straightforward for anyone already familiar with SeaLand or Dometic sanitation systems. It's also compatible with the SeaLand Sani-Sump, making it a versatile choice for a range of onboard waste management configurations. Backed by a one-year warranty, this pump is a dependable option for owners who want tank discharge equipment that performs consistently, season after season.

Frequently Asked Questions
Q: Is the SeaLand 317301200 pump interchangeable with the Dometic 9108554778?
A: Yes, this pump is a direct replacement for Dometic part number 9108554778, so it fits systems designed for that original part.
Q: Can this pump be run without liquid present without causing harm?
A: Yes, because it uses a bellows design rather than an impeller, it can run dry without burning up the motor or damaging internal components.
Q: Does this pump work with automated discharge control systems?
A: Yes, it integrates with Dometic Tank Discharge (DTD) control systems for automated holding tank discharge, though the control system itself is purchased separately.
Q: Is this the same as a vacuum or macerator pump?
A: No, this is a discharge pump, not a vacuum pump, and it operates differently from typical impeller-type macerator pumps.
Q: What is the maximum height this pump can self-prime from?
A: It can self-prime from up to 10 feet (3.3 meters) of water, making it suitable for a range of tank placements.
