Sealand T Series 24V Discharge Pump 317302400
Emptying a holding tank shouldn't be a source of stress, and that's exactly the problem the Sealand T-Series 24V Discharge Pump was built to solve. Instead of relying on an impeller like most macerator-style pumps, this unit uses a bellows design that can run completely dry without burning out the motor. That single difference matters more than it sounds — accidentally running a tank dry is one of the most common ways boat owners end up replacing a pump mid-season, and the T-Series simply shrugs it off.
Beyond durability, this pump is built for consistent, quiet performance. It self-primes to 10 feet of water, moves up to 300 gallons per hour, and draws only about 3 amps on a 24-volt system, so it won't strain your electrical setup even during frequent use. It's also designed to integrate directly with Dometic Tank Discharge (DTD) control systems, giving boaters the option to fully automate holding tank discharge in waters where overboard release is permitted.
Whether you're maintaining a cruiser, a sportfisher, or any vessel with a 24V holding tank setup, the Sealand 317302400 offers a straightforward, dependable way to keep waste management running smoothly. It's a direct fit replacement for Dometic part number 9108554779, so upgrading or swapping out an aging pump is a simple, drop-in process rather than a full system overhaul.

Frequently Asked Questions
Q: Can this pump be used with a VacuFlush toilet system?
A: No. The T-Series is not designed as a vacuum pump and should not be used to operate a VacuFlush toilet system, as this can damage both the pump and the system.
Q: What's the difference between the T-Series and impeller-type macerator pumps?
A: Unlike impeller-type macerators, the T-Series uses a bellows mechanism that can run dry without harming the motor, and it can pass solids up to 1/2" without clogging.
Q: Does this pump require a separate control system to operate?
A: No, it can run as a standalone discharge pump. A Dometic Tank Discharge (DTD) control system is optional and must be purchased separately if automated operation is desired.
Q: What size hose does this pump use?
A: The inlet requires a 1-1/2" hose, while the discharge side can accept either a 1" or 1-1/2" hose depending on your existing plumbing.
Q: Is the 317302400 compatible with 12V systems?
A: No, this specific model is built for 24V DC systems. A separate 12V version of the T-Series pump is available for 12V boats.
