Jabsco Filterless Waste Pump

The Jabsco Filterless Waste Pump (model 50890-1000) is a robust single-diaphragm marine sanitation pump engineered for reliable galley and head discharge on fishing boats, cruisers, and commercial vessels. If you've spent years on the water, you understand that system reliability directly impacts your time away from the dock—this pump eliminates the maintenance headache of filter replacements while delivering consistent performance in freshwater and saltwater environments. Designed for flexibility and simplicity, it fits easily into existing plumbing layouts without requiring specialized filters or complex upkeep.

The Jabsco Filterless Waste Pump operates on a proven single-diaphragm principle that creates a steady pumping action without filter clogging—a critical advantage in marine sanitation where debris and organic matter accumulate unpredictably. Its compact, simple construction supports dry-run capability, meaning it won't fail if temporarily run without liquid, an often-overlooked safety feature that protects your investment during system priming or emergency situations. With 38mm (1½-inch) port connections and a maximum flow rate of 19 liters per minute (5 US gallons per minute), it delivers adequate throughput for typical galley and head applications on vessels up to 45 feet. The unit weighs just 6.8 lbs and measures 8 x 6 x 14 inches, making it easy to install in tight engine compartments or cabin spaces.

Anglers and cruisers who demand long-season reliability benefit most from this filterless design—no seasonal filter swaps, no surprise failures mid-trip, and no environmental contamination from trapped waste bypass. Its 38mm port sizing integrates seamlessly with standard marine hose and through-hull fittings, and the diaphragm-driven action is compatible with both electric 12/24V operation and marine-grade plumbing layouts. Whether you're fishing offshore for weeks or cruising inland waterways, the Jabsco Filterless Waste Pump performs consistently without the burden of consumable filter maintenance, letting you focus on what matters: time on the water.
