The Jabsco Filterless Waste Pump is a powerful, maintenance-friendly macerator-style waste pump designed to handle sewage and waste water without the need for an external filter. Engineered for reliable performance in marine sanitation systems, this pump efficiently grinds and evacuates waste, making it an ideal solution for boats, yachts, and RV applications where dependable waste transfer is essential.
By eliminating the need for a separate filter, the Jabsco Filterless Waste Pump reduces clogging, simplifies maintenance, and improves overall system reliability.
Unlike traditional waste pumps that rely on external strainers or filters, this model uses an integrated macerator blade system to break down waste and toilet paper into a fine slurry. This allows for smoother discharge and significantly lowers the risk of blockages.
Designed to move waste quickly and efficiently, the pump supports longer discharge runs and varied plumbing configurations. Its robust motor delivers consistent performance, even in demanding sanitation applications.
The filterless design minimizes routine cleaning and maintenance, saving time and reducing unpleasant service tasks. This makes the pump especially appealing for boat owners looking for a more user-friendly sanitation upgrade.
Built by Jabsco, a trusted name in marine sanitation, this waste pump features corrosion-resistant materials, sealed motor components, and rugged construction to withstand harsh marine environments and frequent use.

The "Filterless" name comes from the pump's ability to operate without an intake strainer. It utilizes extra-large, single-piece valves that allow solids to pass through without getting caught. This makes it the preferred choice for shower sumps where hair is a constant issue for other pumps.
The ports on the 50890-1000 can be rotated 360°. This is a lifesaver in tight engine rooms or under-sole compartments, as it allows you to aim the intake and discharge ports exactly where your hoses are coming from, preventing "kinked" hoses.
Quiet Operation: Unlike the loud whine of a macerator, the diaphragm action is a low-frequency "thumping" sound that is much less intrusive.
Run-Dry Capability: If the tank empties and the pump continues to run, the diaphragm will not be damaged. It can run dry for long periods without overheating or melting internal components.

"Because this is a diaphragm pump, it is very powerful on the 'suction' side. To prevent your holding tank from imploding (collapsing inward), ensure your tank vent line is completely clear and at least 5/8" in diameter. If the vent is blocked, this pump is strong enough to crush a plastic tank while it's trying to empty it!"
